Different methods can help you repair broken traces from a circuit board. Today, there is a prevailing shortage of microchips that are microprocessors. Traces are what connect microchips and all other essential components on a circuit board.

Damages on Traces

Traces on a circuit board are not new to damage. They can suffer from damage in several ways. They can get damaged due to accidents or even due to dirt or residue. Most of the time, damage on the PCB traces is due to corrosion. Corrosion can happen because there is a leak in the electrolytic capacitor or a leak in the batteries. They can also be caused due to poor storage. To repair broken or damaged traces on a circuit board, you will first need certain tools and equipment.

What will you need?

To start with, you are going to need a soldering iron. Remember that your soldering iron does not have to be the best in the market. However, it is recommended that you have a soldering station rather than just one soldering iron. Along with that, you will need a high-quality gel flex and a very good set of precision tweezers.

You will need a blade, scalpel, or sharp object for cleaning, and a UV solder mask, along with solder, for reapplication. Do not forget that you will also need some wire for the actual trace repair. Afterward, you will need some isopropyl alcohol and some q-tips, cotton buds, and a toothbrush.

It is also very good to have multimeter so that you can keep a check on your work progress. Not to mention, a multimeter will be beneficial because it helps you keep a check on your work to make sure you’ve renewed continuity in the damaged traces.

Other things you’ll need include very sharp eyesight and a steady pair of hands. If you don’t have good eyesight, it is always a good choice to use a microscope. A microscope is an effective way to se what you’re doing without making errors.

You can even connect a camera to this microscope to enhance your work. Since a microscope can be pricey, they are not easily available. In this situation, a magnifier is a better alternative when trying to repair broken traces on a printed circuit board.

Use Enameled Wire

You should use enameled wire, the same type of wire you would use on a transformer or an electromagnet. It has an enameled coating, which means that it is insulated, making it very functional inside a printed circuit board. Nonetheless, this enameled coating comes off very easily with the heat of the soldering iron.

So if you need to run a trace over the board where it might come in contact with other metal, the insulation will stop it from creating a short. As you can see, repairing broken traces on a printed circuit board requires extensive consideration and thought, and you must be willing to take all the precautions to do a clean job.

To Conclude

With careful consideration and some knowledge of printed board repair, you can easily repair the broken traces on a printed circuit board. The above-mentioned types of equipment can help make the repairing process easier. All you have to do is spot the broken trace, clean the corrosion, and apply new wires on them with the help of solder.
