My PC friends probably think I am crazy, but the weight of the decision of why I purchased an Apple MacBook Pro fell on five key points of comparisons to other laptop computers.

Apple MacBook Pro vs. Netbook PCs

  1. Ease of Use

  3. Versatility

  5. Value (Price divided by the first four points)

My notebook story begins with searching for a good quality, fast speed, good display screen, a comfortable track pad, good software, ease of use, long life battery, ability to do videos and pictures well, but low priced netbook or small laptop for mobile/portable/travel use. I quickly found that there is no such creature like this.

I stopped in over at Fry’s and started playing with the various new Windows 7 Netbooks from Acer and MSI. At first glance I wanted to really like these netbooks, but it was only a short lived infatuation. There were more than a few barriers to taking these netbooks from a foolish liking to an in-depth affection. For one, they were small. Now, that may be good in one aspect for portability, but for another aspect of screen size, it was very difficult to get comfortable with the small screen size. Those of us that are requiring reading glasses are sure to find these screens are much too small. Sure, the price was low at around $350.00, but look at what you are getting for that.

With these netbooks, this really is a case of getting what you pay for. Slow processor speeds, low memory, no dvd/cd drive, and a new operating system with Windows 7 that is all déjà vu. The Windows 7 operating system loaded on these netbooks feels like an upgraded version of Windows XP, with things moved around a bit and other things very difficult to find. Of course, this is the dominate format for these netbooks. Simple things like how to change the icon sizes on the desktop took me 10 minutes to find. And, that was after I spoke with the sales people, though that brings up the topic of the sales people may not have the best of training either. That’s another story. In any case, three of the sales people that I spoke with could not figure it out. It wasn’t located in the Windows 7 control panel area, as one would think. Finally I did what would be a right click with a mouse on the desktop, though I am not sure how I did it with the netbook trackpad, but I was able to change the default icon size to a smaller size.

Speaking of touchpads or trackpads, I have grown up on a mouse in the house for both PCs and Macs. So, this really was my first time investigating and comparing track pads. The trackpads on these netbooks and mini laptops seemed to be engineering afterthoughts. Actually, they lacked quality engineering and no consumer testing. The one that bugged the heck out of me the most was the trackpad on the MSI mini laptop. It felt like sandpaper on the tips of my fingers after playing with it for 10 minutes. Actually, I ended up pulling another customer over and asking him what he thought of the touchpad. His thoughts were exactly the same as mine. The trackpad had a very textured finish that was not comfortable to the touch. I can only imagine what it would be like after navigating with this trackpad for an hour or so. I would have to put Band-Aids on my fingers. Definitely not a very good touchy-feely experience.

So, I decide that maybe I needed to move up in price and screen size. I moved up to the mid range for laptops. However, there seemed to be a void in the size from the 8.9 inch – 11 inch version mini laptops to the 15 inch larger laptops. Price started going up significantly as I wanted a more powerful laptop that could do various types of mult-tasking, and still stay with a useful but compact size. Next thing I knew, I was up around the $700.00 price tag. But, still I had issues with trackpads, and the lack of ease of use.

So, I ventured over to the Mac table. Being an equal opportunity user of both Windows PCs and Macs and am well versed in both the PC and Mac land, having owned many versions of Windows PCs and an iMac G5 for a number of years. I have also had the opportunity to have hands on experience by having friends allowing me to play with their MacBooks for various applications. When I went over to the Mac table, it was a breath of heaven to feel and touch the new MacBooks.

MacBook Pro
My First Thoughts on the MacBook and MacBook Pro

The first thing that stood out to me was the ease of use. The trackpads are very very easy to use. Having a Multi-Touch Trackpad that is large, smooth, extremely powerful, two finger scroll capable, two finger pinch zoom capable, two finger rotate, and even two finger right click or secondary click capable with the full complement of right click commands available. Additional trackpad features include three finger swipe navigation to go forward or back in browser history, four finger swipe left to right to switch applications, or four finger swipe up down for exposing the open applications. You can even set the one finger to tap to click, dragging, drag lock, and secondary click to bottom left or bottom right corner. Track speed, double-click speed, and scrolling speed can all be individually adjusted to just the way you want them.

MacBook Pro Keyboard Trackpad

With this MacBook Trackpad, you will quickly find out that a person can go from using a mouse to very easily using the Multi-Touch Trackpad in no time flat.

Another aspect of the MacBook that makes it a joy to work with, is the ease of use of the Mac OS X Snow Leopard. While any new software will take time getting use to, the learning curve for the Mac OS X is very fast. I think part of the reason for this is the intuitiveness of how the things are laid out. Apple also has some very good quick training videos that are quite helpful. Take a look at some of the Mac tutorials on how to do things.

Mac OS X Snow Leopard operating system is a pleasure to work with. It is very intuitive, which makes for a very easy transition to go from working with a Windows based machines to a Mac based operating systems. Of course, I am a bit biased in this area, since I have been using both Windows and Mac machines for quite some time. Never the less, some friends of mine who had been with Windows their whole lives, recently made the switch to Mac, and the operating system switch proved to be a very easy transition for them.

The high quality of the Apple MacBooks can not be overstated. Everything fits together like a form fitting glove. The opening of the screen display has just the right amount of hinge tightness. As I stated before, the trackpad is very smooth, and seems to just fit perfectly for your hands and fingers on the keyboard area. The keyboard has automatic backlighting, which in dim environments is great for quick reference. The MacBook Pro comes in a very sleek, 1.08 inches thin, aluminum unibody construction.

I bought the 13.3 inch MacBook Pro with the glossy widescreen display. This for me was the perfect fit for size and portability, but has plenty of desktop space with a screen of 1280-by-800 pixel resolution, made this one the ideal laptop solution for viewing documents, web sites, videos, and pictures.

The weight of the MacBook Pro 13 inch at 4.7 pounds is very manageable. It easily fits into a briefcase or backpack. I also suggest a carrying case to protect your MacBook. I decided to go with the Incase Nylon Sleeve Case for the Apple 13 inch MacBook Pro. The MacBook Pro fits perfectly in this padded case and provides extra storage areas on both sides for accessories. The case and the MacBook Pro worked out perfectly for a recent vacation trip from California to Florida with several layovers. The case added the extra protection and allowed me to quickly place the MacBook in my carryon suitcase, and quickly remove it for airport security checks. The case also comes with a removable shoulder strap and is available in three colors, black, graphite, and mustard.

The MacBook Pro is such a pleasure to use for all aspects of computing. For example, when it comes to viewing video on the screen, it is second to none. The display is rich in color, bright, and vivid to look at. Movies are cool to watch and when it comes to catching up on your television shows like Flash Forward episodes, it is incredible to watch it on the MacBook. It’s as though watching it on the MacBook Pro is better than on the TV screen. The stereo sound quality from the computer is great too. The audio level has decibels of sound to spare. You can actually make the sound too loud for others in the room. Forget trying that with any other netbook.

With the built-in iSight camera and microphone, doing a Google Video Chat was simply amazing. The camera and built-in microphone worked great together. I was able to use the camera in both low light and regular lighting conditions. The chat session was perfect. There was no audio feedback and the person on the other end said the audio and video were perfect too.

The battery life is rated at 7 hours, but that is under somewhat controlled conditions. Apple quotes the following from their website:

Testing conducted by Apple in May 2009 using preproduction 2.53GHz Intel Core 2 Duo-based MacBook Pro units. Battery life depends on configuration and use. See for more information. The wireless productivity test measures battery life by wirelessly browsing various websites and editing text in a word processing document with display brightness set to 50%.

I typically like my screen brighter than 50%, and was able to generally get about 5+ hours of battery usage on three battery cycles. However, I was playing videos, browsing the Internet through wireless connections, and searching for other wireless Internet connections during this time.

The charging plug is held in place with a super strong magnet, which if someone catches the cord will simply pull the connector off the MacBook without pulling the MacBook down to the floor. Definitely a great safety feature. the charger is very compact, and fits nice and flat inside one of the Incase pockets I bought for the MacBook Pro.

The MacBook Pro 13 inch that I purchased has the 2.53GHz Intel Core 2 Duo processor, 4GB (two 2GB SO-DIMMs) of 1066MHz DDR3 SDRAM; which supports up to 8GB of memory, 250GB Serial ATA; 5400 rpm hard drive, and 8x SuperDrive (DVD±R DL/DVD±RW/CD-RW).

By the way, if a person really wants to have their cake and eat it too, in the form of Windows 7 on their MacBook, there is another feature that lets a person load any operating system they wish. Boot Camp is a utility included with Apple Inc.’s Mac OS X v10.5 "Leopard" and v10.6 "Snow Leopard" operating systems that assists users in installing Microsoft Windows XP, Vista or 7 on Intel-based Macintosh computers. Boot Camp guides users through non-destructive re-partitioning (including resizing of an existing HFS+ partition, if necessary) of their hard disk drive and using the Mac OS X Leopard disc to install Windows drivers. In addition to device drivers for the hardware, the disc includes an applet for the Windows control panel for selecting the boot operating system.

In addition to Boot Camp, there are other avenues that are also available such as, VMware Fusion 3 and Parallels Desktop that provide the means of loading Microsoft Windows and other non Windows operating systems such as Linux OS onto the MacBook computers. Both VMware Fusion 3 and Parallels Desktop are helpful software applications that allow folks to run Windows applications directly and concurrently on their MacBooks and quickly switch between the two.

There is also an open source software, VirtualBox, available from Sun. VirtualBox is an x86 virtualization software package, originally created by German software company Innotek, now developed by Sun Microsystems as part of its Sun xVM virtualization platform. It is installed on an existing host operating system; within this application, additional operating systems, each known as a Guest OS, can be loaded and run, each with its own virtual environment.

“Presently, VirtualBox runs on Windows, Linux, Macintosh and OpenSolaris hosts and supports a large number of guest operating systems including but not limited to Windows (NT 4.0, 2000, XP, Server 2003, Vista, Windows 7), DOS/Windows 3.x, Linux (2.4 and 2.6), Solaris and OpenSolaris, and OpenBSD.”

I have to say that the MacBook Pro is really a great all purpose laptop computer for business, school, and personal use. With ease of use, superb quality, immense versatility, and an awesome form factor, the value of this MacBook Pro computer is outstanding. You won’t want to leave home without it!

The days of using a 20 watt soldering iron from Radio Shack are long gone when it comes to repairing lead free soldered circuits in Apple Computers, PCs, and other lead-free electronics equipment.

With multilayer boards, thick ground planes and power planes, and high temperature circuit board materials, along with countries having bans on the use of leaded solder in circuit boards; electronic components are now being attached using lead-free wave soldering or pick-and-place machines using conductive epoxy flux adhesives and then heat cured. All of this adds up to quite a bit of difficulty in reworking and repairing circuit boards today.

CHIPQUIK at While it is good to keep our environment clean, I think the wide spread use of lead-free solder in printed circuit board assembly processes is a case filled with a manufacturing life of unintended consequences. There are major challenges that have and continue to affect printed circuit board manufacturing around the world. First off, PCB materials must be able to withstand lead-free soldering temperatures of up to 260[degrees]C during the assembly operation. [1] This in itself, requires the use of more expensive, and much more difficult materials to work with at the PCB manufacturing stages. Not only is the multilayer construction much more difficult to deal with, but the drilling of the holes in thick multilayer circuit boards, with circuit board materials that are of a “harder” material nature, as compared to traditional FR-4 resin systems (not designed for lead-free), directly adds to the manufacturing costs involved.

I also find it interesting, that about the time where the world (pushed by the European Union) started converting over to using lead-free PCB manufacturing techniques, there seems to be a correlation between the electrolytic capacitor failures that started to occur a short time later in TVs, Set-Top Boxes, Computers, PCs from Dell, Apple, and other computer manufacturers, along with a host of other high powered electronic gadgets. I have no way of proving it, but I suspect that many of these components were hit with a large temperature blast through either high temperature wave soldering processes or oven based curing used in the finished component filled PCB assemblies.

“With a melting point of 217°C, SAC solder also is closest in melting point to the conventional lead–tin solder. This does mean, however, a yet-unquantified increase in energy use. Furthermore, the higher temperature may pose problems for the electronics industry. Higher temperatures mean more stress on components and the entire manufacturing process, notes Geibig. Higher temperatures also mean increases in the time it takes to make products, because more time is required to heat and cool the products during the course of their manufacture.” [2]

On July 1, 2006 the European Union Waste Electrical and Electronic Equipment Directive (WEEE) and Restriction of Hazardous Substances Directive (RoHS) came into effect, prohibiting the intentional addition of lead to most consumer electronics produced in the EU. California recently adopted a RoHS law and China has a version as well. [3] In order to meet the new directives established by the EU on removing the lead from electronics, has greatly affected the PCB assembly world at large. In effect, countries that did not have directives for the use of lead-free electronics assembly, were forced by default of having to build to meet the international requirements from the EU.

“This directive (EU Directive 2002/95/EC) places a restriction on the use of certain hazardous substances in electrical or electronic equipment sold or used in the European Union (EU) after July 1, 2006 with some exemptions.” [4]

‘Within the United States, California’s Electronic Waste Recycling Act imposes a fee on “covered electronic devices” currently being sold within the state. This fee is intended to cover the cost of properly disposing of the products when they become waste. Second, it requires “covered electronic devices” sold in California after January 1, 2007 to meet the same requirements as those found in European Union Restriction of Hazardous Substances (RoHS) legislation. Electronic devices containing toxic metals and not complying may not be manufactured, sold, or imported into California after January 1, 2007.’ [4] Other states have enacted similar laws.

So, what does that mean for circuit board and electronics repair folks today looking for ways to extend the service lives of their equipment? Well, there are some special soldering techniques that are involved to do the electronic repair jobs right.

What is required to repair lead-free circuit boards with large discrete components?

These lead-free soldering tips are specifically geared toward the large discrete components such as: electrolytic capacitors, transistors, diodes, bridge rectifiers, and coils (inductor chokes). Information on how to repair and replace surface mount devices with lead-free soldering techniques is waiting for a later date to be written.

1. The minimum wattage for a soldering iron needs to be 60 watts. The 60 watts rating is only part of the specification to consider. Be aware that some soldering irons actually get hotter than others given the same wattage ratings. Additionally, you will need to consider using a proper soldering tip for the job at hand. If you are trying to solder on a thick multilayer PCB, then a wide tip is absolutely required to do the job right. There is also a difference in the coatings between the lead-free tips and the old standard Pb tips used for the standard 60/40 Tin Lead (60/40 Sn/Pb) Solder. 60/40 Sn/Pb melts at 370 °F or 188 °C while various lead-free solders used in PCB assembly have a melting point range of 415-441 °F or 213-227 °C . It is important to note that the increase in the melting temperature for lead-free solder, does not tell the whole story for proper solder joints involved with component replacements and PCB repairs.

You might be thinking, that the soldering iron I will be using gets up to 850 °F, I should be able to repair any lead-free soldered component on any PCB. That is wrong thinking here. I mentioned at the beginning about having a wide tip when soldering a thick multilayer. But, you need more than a wide tip. The soldering iron, at the tip, must be able to quickly recover on the heat cycle. It must also be able to supply the heat continually at a constant temperature, or near constant temperature to do the job right. This is where the wattage of the soldering iron is a factor for delivering the heat continually.

A thick multilayer PCB acts like a huge heatsink, sucking the heat away from the area that you want it, and dissipating it over the area where it is not required. If you use a small caliber soldering iron to try and remove components on this type of PCB, you will more than likely simply heat up the circuit board in a wide area, including the component itself before the solder will ever melt. In fact, it is quite likely that the lead-free solder will never melt, because the soldering iron can not quickly and effectively localize the heat in a high enough concentration to do any good. Actually you will probably do more harm than good.

I have heard from some folks, and talking from experience, that you will end up throwing a few choice words around that will not endear yourself to your spouse, if you try to use a low powered soldering iron. Even if you do manage to remove the component, the new component you install will have either the poorest of a solder joint, making you look like an amateur, or worse, an overly heated and damaged component that will result in early failure. Solder joints made with a low wattage soldering iron will likely result in cold solder joints, which will result in poor electrical connectivity and a non-working circuit board.

How about a portable butane powered soldering iron, won’t that work better? Been there and done that. Take it from experience, the answer to that question is no. I tried a wide tipped butane powered soldering iron and I was not able to even make a dent in the lead-free solder on a Apple iMac G5 motherboard.

What about a soldering gun? Once again, been there, done that. It doesn’t work with even the highest powered soldering gun. Soldering guns are not really designed for circuit board repairs. Take it from experience, put this idea out of your mind, it won’t work.

So Jim, what do you recommend in a soldering iron? Do you recommend a lead free soldering iron or a lead free soldering station? Let me first say here, that I have recommended some soldering irons and soldering stations to folks that have written to me and asked for my advice on various Apple repairs, and I would be more than happy to recommend something if you send me an email request. I will say this, that you can get a very good one at a very decent price. You don’t have to spend hundreds of dollars on a soldering station. However, don’t make the mistake and think you can get by with the old hobby soldering iron that you have in the desk drawer. Trying to use a substandard, low wattage soldering iron for lead-free motherboard repairs will give you headaches galore.  Actually, I would like to hear more from readers of what you have used for lead free soldering.

2. What is the best way to remove the electronic component such as a electrolytic capacitor off a thick multilayer PCB once I have a good soldering iron or soldering station? I suggest you have the PCB standing up on edge, so that you can work from both sides of the circuit board. Check out the Chip Quik kit for removing the capacitors in difficult circuit boards. While heating up one leg of a radial electrolytic capacitor from the bottom, and at the same time slightly pushing the capacitor from the top, away from the leg being heated, at which time the solder starts to melt, the capacitor leg will start to move out of the hole. Do this for the other leg, alternating back and forth to each leg, and slowly work out the capacitor from the hole as the solder melts. After the capacitor is removed, a solder sucker can be used to remove a lot of the excess solder in and around the circuit pad. Using solder wick, (also referred to as desoldering wick or desoldering braid) on the thicker boards does not work well because of the extra heatsinking that occurs when the solder wick is applied. At this stage of the component replacement repair, invariably, not all the solder will come out of the holes with the use of a good quality solder sucker. This is where I suggest using my next soldering tip.

3. Try using a sewing pin, with a plastic head, (even a correct size safety pin works) and heat up the tip and the solder pad at the same time, once the caps are removed. This will push the solder out of the holes and solder will not stick to the steel sewing pins. Stop in at your local sewing machine center and you will find a large assortment of sewing pin sizes. Select a sewing pin size that matches up to the size of the leg of the capacitor. Once the pin is pushed through the hole, continue to apply heat to the pin and the pad, and move it in and out, making the hole the right size for your new components.

4. Is it best to use lead-free solder when installing the replacement capacitors? I have mixed thoughts on this. On the one hand, since the board is already using a lead-free solder, I would say stay with using lead-free solder. Yes, standard 60/40 lead solder is much easier to work with, due to its lower melting point, and some folks say it seems to work fine, but I have some reservations about using it. One negative item to be aware of here is that it is much more likely to end up getting cold solder joints when mixing solder types, and the other concern is, there may be a reduction in the soldering iron tip life if using the special plated tips designed for lead-free soldering, and using leaded solder.

I do have one major item that must be adhered to; only use a rosin core type of solder. Do not use acid flux. No acid flux. Acid core solder and acid flux will damage the circuit board and/or the components. With that being said, it is important that what ever solder is used, that the old solder and the new solder join (melt) together when installing the new components. Be careful with this that you don’t under heat or over heat your work. Just the right amount will do. It is hard to describe how much, and how long the heat should be applied to get a good solder joint. Take a close look at your solder joints. If they seem to be loose, then reapply the heat until the old and the new become one. As an additional note, and I have to say once again as a matter of importance, remember that the components themselves do not like it too hot for too long.

NC600 Lead Free Solder No_Clean Flux Core To properly solder motherboard capacitors on thick MOBs, you will need to operate the soldering iron or soldering station temperatures at or near maximum temperature settings. Heat up the pad on the bottom first and foremost by having most of the soldering tip on the pad; while at the same time having the tip touch the capacitor leg. I strongly suggest using lead free rosin core solder with a no clean residue; which you can purchase with your capacitors order at The no clean flux rosin core solder simply means that the center of the solder has a flux rosin core that is activated by heat, and the remaining residual flux does not need to be cleaned off the circuit board and will not harm the onboard circuitry. Remember also, that the MOB has residual lead free solder already present on the circuit pad and lining the circuit board hole walls, and must be melted (typically referred to as “wetting” action) with the new solder to form a good solder joint. If you use standard 60/40 lead solder for soldering, it is much more difficult to do the job just right, and is much more likely to produce cold solder joints because the different types of solders melt at substantially different temperatures and will not properly join together.

Be careful of other small components and surface mount devices (SMD) on the bottom and top of the boards. These devices are so small, that many times they can be damaged or unattached to the PCB simply by accidentally placing the soldering iron tip on the surface mounted component soldered leads, either moving it or bridging the leads with solder. So what I am saying is, try to use a steady hand.

The picture above, of the custom circuit board clamping hands-free support system, is the brainchild of Paul N. — Grayslake, IL. Paul writes, “You can buy a 12″ x 2.5″ (depth) wood-working clamp from Home Depot for about $10 and a 3″ ‘C’ clamp for another $5. Then apply some adhesive-backed, dense foam rubber on each face of the wood-working clamp. Note that I removed the hard rubber covers that were on the clamp originally.” Paul calls the device the, “Kludged Circuit Board Clamp.” It is important to note that when clamping the circuit board with any clamping device, that you do not position the clamps on top of any components or the very small low profile SMDs on either side of the PCB.

There is another lead free soldering/unsoldering components helper that is simply amazing! Check out the video of the Chip Quik lead-free unsoldering kit and system of replacing components on circuit boards. I highly recommend this patented SMD and discrete components removal kit.
