I was etching a board yesterday and in my haste I made the etchant too hot.:?

This has left some of my tracks a bit flakey but on the whole it is fine.


Does anyone have any tips on repairing over etched tracks on copper clad board?

Thanks
John

Hi!

You can use liquid tin, normal tin with flux or a special silver pen.

for really bad undercutting, I have sweatted down a piece of 30 GA wire wrap wire onto the track. this also helps when you need more current thru a narrow trace.

I got the silver pens. It cost alot for a pen, but it did the trick.

Thanks

if theres not a lot of missing tracks you could just drill 2 holes and use a wire jumper in its place.
