Need solutions for selectively removing solder mask from a PCB. Most likely a chemical process
- Identify chemical options
- Identify masking solution
- Determine storage, disposal, equipment requirements
Need a process for growing a nice orange oxide layer on fresh copper
- Presumably some sort of controlled oven solution
- Need to practice with heat gun to get a sense for timing and sensitivity
Need a process for protecting bare copper from oxidation
- Presumable by applying some kind of lacquer coating
