This technical “how to” manual describes in detail the repair process, the tools required, the level of skill required-good, better and best- for each of the repair processes. PCB repair techniques in this document go all the way from the replating of gold fingers to solder mask repair to repair of laminate damage.
The specifications call for customer involvement if a physical repair as outlined in the repair manual is required. The techniques for repair are broken down in this specification into beginner, advanced and expert PCB repair technician levels. In some cases, there may up to 4 different approved repair methods outlined in the IPC-7721, all of which will get the board back to a functioning PCB.
