Default Through Hole PCB repairs with miniature eyelets:

Through hole pcb's are nearly obsolete now with surface mount being king. I only realized this recently, that they are now truly "vintage".

Recently I acquired a North Star S-100 disk controller board, and got that sinking feeling when I discovered that somebody had been attempting repairs in the past, and I discovered track & pad damage. I think we have all been there and had that sinking feeling, at least those who like to do their own board level repairs.

In any case I had also noticed a very impressive pcb repair done at the factory I think, on my SOL-20 computer motherboard where they had a used a miniature brass eyelet to do it. So I had a go at this technique myself to repair the North Star card.

The technique would also be very helpful on damaged phenolic pcb's in vintage transistor radios. It was pretty easy to make the simple tools to do it.

The result is here:
