Both use aluminum as the board material. One only has a couple small rows of pins that are integral to the board. I know it's not "pin board" grade. I don't know if I should just remove all the AU plated connectors including the pins or leave as is. BTW, for now I left a couple of relays attached due to them having AU plated pins and being held in place by AG plated nuts. The other board with wire wrapped pins has a lot of dark colored non insulated wire which I believe may be AG. So, does the AL board mean disqualification from Pin board category or is that the material generally used? If the wire wrapped board is pin board, is it clean enough as is? Thanks!
