So im gonna start my little project today to repair a blown circuit by building a replacement and i have a few questions. first one is, while slightly widening a perfboard hole to accomidate 2 legs to fit, the copper ring around the hole detached, about 80 percent of it came off. while i was able to make the connection and the solder adhere to the copperless hole, i was still wondering if this would cause any problems? the next one regards traces on perfboard. referencing the photo below, all the copper tracings exposed and not covered in solder on the circuit below would be replaced by actual solder acting as the trace if built on perfboard correct?
