Really depends on the damage you want to repair but I have had luck with window defogger repair kits from auto stores which are basically a liquid conductor that you paint on.

I've used CirKit repair kits & they are very useful.

I found that the eyelet setting tools don't always make a good contact on the track.
If you use the end of a centre punch,or similar to finish the eyelet off,you can do a very nice job.

They are too damn expensive,though!
Way back in the day,they were a lot cheaper comparatively speaking,but I suppose,with a smaller market they have to make more profit on each kit.

Are the eyelets supposed to make a gas tight weld or just physical contact + solder between what remains of the original exposed copper on the PCB and underside of the eyelet?

[vk6zgo]

Tight physical contact---I find that if the peened over bit isn't "snug" to the track,it is hard to get a satisfactory solder joint.

My PCB repair kit was 5 tubes of assorted superglue, from thin to thicker than molasses, and a roll of kynar solid core wire. As well a set of needle files and a desk lamp and a few magnifying lenses to see the close up, along with some dental picks. Worked to fix 4 layer boards that had a very old copper trace that would lift even if you looked too hard at it, only thing keeping some boards together was the Mesoupolet K conformal coating that they were dipped in. I have a cheap hobby drill and a large collection of small bits as well to make new holes to anchor the wire to the board.

I've pretty much done the same,as most of the time I couldn't get my hands on the Cirkit stuff!
One kit for about 5 different departments!

I used them when I could,though,& they are very useful.

Sometimes,I peeled tracks off old PCBs,cleaned them & reattached them to the board I was repairing.

It's amazing what you do fix over the years!

A switchmode supply in a picture monitor blew up in a big way,burning 25mm holes where some of the rectifiers lived.(two diodes in one pack).

It looked like a candidate for the bin,but I decided to try,anyway.

I reamed out the holes,epoxied in some small circular PCBs that were for some forgotten project,modified the tracks,connected  the required bits,replaced other cooked parts,put it together & away it went!

There was one board where the repair was to order a new one, complete. You are not going to repair a board that is a solid black charred block with pieces of transformer vaguely visible sticking out of the foamed up remains of the epoxy encapsulant. The replacements were a 8 figure cost........... Each.  They came in the post in an ordinary parcel. Took about 2 days per unit to remove the old ones and clean up the case enough to put a new one in as well.
