if a printed circuit on a circuit board is snapped is it unrepairable ???

 

Put up a pic of both sides and I will give you the verdict!

 

Whole board snapped in half, or just a few tracks ?

Whole board repair would be difficult but doable, few tracks would be easy.
I wouldn't vouch for the repair's ability to withstand vibration in either case though.

The above applies to single or double surface boards, if the board is a multi-layer type, forget it, unless you are prepared to replace the broken tracks with soldered wires which would require a complete circuit diagram, and, would only work if the circuit isn't dependent on the layout (e.g. high speed data transfer applications).

 

its a pioneer rca adapter, one track is snapped on the underside and im 90% positive its just a single layer board

completely my fault so i only have myself to blame lol

matt

 

That should be repairable with a thin piece of wire and some solder I would have thought

 

i have done a single layer with a soildered wire but it was only one track.

 

Agree!

 

i was thinking a small dab of solder just over the track could poss fix it

 

Only if the board is braced/glued with a plastic cross-peice. The solder joint on its own will not be reliable otherwise.

 

doug, now youve lost me lol

do you mean for a board that is snapped in half of just the one track ?

ie the board isnt snapped its all intact its just a track that i have snapped

 

Then you should be ok, but solder is notorious for filling in gaps where you don't want it, and not jumping gaps where you want it to The wire resolves that issue.

 

I thought that the fibre-glass board had broken (snapped)....But if it's just a track that has cracked then a blob of solder over the crack will be OK (ish)......

But as Frog said, a link wire from one side of the break to the other side would be a much better repair.
