PCB solder pad repair & corrosion clean up - The epoxy method

This is a demonstration of a PCB repair which involves repairing damaged surface mount solder pads as well as cleaning up corrosion from a leaking electrolytic capacitor. The pads had been damaged by the owner of the motherboard as a result of him trying to repair the board on his own. I hope that this video will give you some ideas on how to perform a proper pad repair using the epoxy method. During this repair, I used an epoxy that is heat resistant up to 315°C for 60 seconds. If you ever find any kind of epoxy on the market that is specified to be heat resistant up to more than 315°C, then I would be happy if you could let us know about it in the comment section as it does appear that high temperature epoxies are quite difficult to find. The following products was used in this video: CircuitWorks CW2500 - Two component epoxy overcoat CircuitWorks CW3300 - Overcoat Pen I have made several videos before where I have had to fix up other people's mistakes that they have made during their repair attempts, and this repair only adds on to the list. If you are not a repair technician and your motherboard has stopped working, it would be in the best of your own interest not to attempt a repair that you really cannot handle. Because there is a huge risk that you will actually end up doing more harm than good. We are of course mostly talking about board damage in the case of motherboards, but it gets considerably worse when dealing with things like power supplies, which can easily become a great shock hazard to inexperienced technicians and even result in electrocution. As always, comments and questions regarding this repair are always welcome.

Making a Circuit Board From Scratch

Here, I make a control unit for creating chaser animations for my various Satelluxe creations ( It's composed of two circuit boards, one that handles the logic and another to control the high-voltage loads. The full circuit is programmed with numerous animation patterns, the speed and brightness of which can be adjusted with a control panel. Note: This video is not intended to be a tutorial. To learn the ins and outs of making PCBs at home, Google "PCB toner transfer method." However, I have included some notes below. If you have a question, I'm happy to answer it in the comments if it hasn't already been answered here.

As you might be able to tell, this particular stock had been sitting for quite a while and had become pretty cloudy. ▶ The laminator I use is GBC's Personal Laminator, model 1701987. It's no longer manufactured, but you can find a current, recommended model at This is where I was led to the GBC I use, which I've been very happy with for a number of years. ▶ I use an HP LaserJet HP1102w in this video, but most laser printers will work. (The toner in Brother printers is generally reported not to give good results, however.) Will your specific printer work? I don't know, since I don't have one to test. ▶ I wear cotton gloves once I begin cleaning the copper-clad board (a) to avoid contaminating it with oils before applying the toner mask, and (b) because the boards get pretty hot coming out of the laminator. ▶ I use Goof Off Professional Strength Remover to clean the boards and to remove the toner, but regular acetone works, too. ▶ The etching solution is 2 parts hydrogen peroxide (available at any drug store) and 1 part muriatic acid (available at nearly any hardware store). ▶ The toner mask sometimes looks white because, with the HP paper I use, a thin layer of paper sticks to the toner. It appears lighter or darker depending on lighting and moisture. ▶ The "silk screen" on the top is added simply by using the same toner-transfer process. ▶ The red thing with all the holes in it is a homemade fume extractor. ▶ I program the microcontroller using an Arduino Duemilanove (see above for newer model) through the USBTiny ISP Programmer (see above for newer model). Note: I cannot provide support for these items. ▶ The spray I coat the circuit boards with is Techspray's Fine-L-Kote HT, a conformal coating that prevents oxidation. It can be soldered through if necessary. ▶ I created the original circuit box from modeling styrene, then molded it using Smooth-On Mold Star silicone. The cast is made with Smooth-Cast 320 resin. Casting a box is a little pricier, but saves loads of time over building one from scratch every time.
