Four methods to repair broken PCB traces?

By Applied Electronics - Thursday, December 29, 2016 No Comments

There are number of methods used to repair brunt and broken PCB traces. Some are as follows

1. Thin copper wire or aluminum wire
2. Conductive silver pen
3. Using pencil because graphite is highly conductive
4. Wire wrap

 1. Thin copper wire or aluminum wire

 The best method depends on many things but experience is the main factor. Usage of copper and aluminum wire seems to be the best option and adopted by many. Advanced technique called epoxy method is also based on using thin copper wire and is adopted by professional PCB designer and PCB house. There are many steps to follow when advanced technique is followed but the general steps is to first clean the broken trace using isopropal alcohol and then add required tiny piece of copper/aluminum wire as the new traces where during the placement Kapton tape can be used.





2. Conductive silver pen  

The conductive silver pen are used but tends to be difficult and





 3. Using pencil because graphite is highly conductive

  Using pencil is actually not a permanent solution or whether it should be considered as a solution at all. But to mention you could fix the broken copper traces using just pencil because the graphite is highly conductive.

4. Wire wrap

 Then there is wire wrap which is actually used to fix wires connecting different parts of the equipment like telecommunication equipment but it is reported that people use wire wrap to fix lost PCB traces.
