Other times, it’s just a matter of looking for a burned area that indicates that a failed component or a pad or trace needs to be replaced and rejoined to the existing track on the PCB. Sometimes, diagnosing a damaged and inoperable PCB requires the application of an oscilloscope to probe the signal strengths and waveforms at various points to test for continuity of the circuit across the board. First, secure the PCB to your work surface so that it doesn’t move around while you’re working on it. Step 1: Remove the damaged pad or component. Then carry on with our quick guide to restoring a damaged PCB to functionality, as discussed below (see also this Instructables guide on repairing damaged PCB pads):

Sharp knife or flathead screwdriver or very fine sandpaper.

Some of the most common repairs performed on PCBs are those performed in the aftermath of heat and physical damage and excessive voltage applied to components.Ī PCB with heat-damaged components (Source: An engineer who wishes to remain anonymous)Įven though the fiberglass, copper, and glue layers within board construction are fairly resilient against the buildup of heat, some PCBs are more prone than others to delamination and other heat-related symptoms.įirst, gather the tools and other materials that you’ll need: Step-by-step instructions for a simple PCB repair

CIRCUIT BOARD TRACER REPAIR KIT HOW TO

Knowing how to diagnose problems with these boards and repair or replace failed components means that a technician can perform troubleshooting on a wide range of computerized assets and internet of things (IoT) devices. Both the consumer and commercial landscape rely on ever more sophisticated electronic devices, most of which require PCBs.

On the hobbyist as well as the professional side of things, an understanding of how PCBs function and how to restore them is essential if you want to learn how to build and maintain your own projects and systems, such as the following:Įlectrical engineers have even more motivation for pursuing a masterful knowledge of this fundamental skill. People who have a passion for electronics, and for upcycling or getting the maximum lifespan out of something, can find a lot of satisfaction in the process of locating damaged tracks or identifying failed board components, replacing them, and restoring a PCB.Ī PCB with a delaminated copper track (Source: An engineer who wishes to remain anonymous) This is the first reason why it makes so much sense to learn everything that you can about repairing PCBs. Why bother at all with learning component-level board repairs for PCBs? Don’t we live in a throwaway culture in which it’s OK to toss electronics in the landfill at the first sign of trouble?

However, there’s ample reason for tinkerers and hobbyists to dive in, too - it’s a first step toward more advanced electronics repair work. There are more than a few good reasons why electrical engineers should be more than confident in their PCB skills. How do electrical engineers perform repairs on printed circuit boards (PCBs) and how can you master this skill for yourself? More to the point, why would you want to and how can it be beneficial for your career?

Once you’ve mastered this skill, you’ll find that it unlocks further interest and additional opportunities to explore electronic repairs ranging from simple to complex.
