We assume by "solder hole" you mean void. We believe void formation is driven by the thermal recipe that you've chosen to use. Search the fine SMTnet Archives for further discussion. There is a tremendous amount of current industry discussion on v

On a previous black pad experience we soldered a wire to a fiducial and did a pull test to failure. On the black pad board the wire and solder pulled of clean leaving the fiducial on the board. On good boards the copper came off with the wire. If you

You can purchase pad repair kits at some "radio shack" type stores or you can order them from some such as Circuit repair corp. If you know where the signal traces go from the individual connector pins I woul;d recommend just adding a wire frm the p

Copper wire will become thinner when dipped in tin/lead or lead free solder. The copper is disolved off of the bulk wire. This is one reason rework on solder pots must be restricted. Eventually, after repeated cycles you will have smaller and sma
