On most finger boards (ISA/PCI/PCIx) the plating process is "selective" meaning only the fingers are plated and all other copper features (traces, vias and pads) are not gold plated, but most likely HASL (Hot Air Solder Leveled). There are some power boards and processor boards and in older cases, RAM sticks that are immersion plated meaning under the solder mask, all copper is gold plated.



My question is does any vendor look for specific immersion RAM or boards and pay accordingly? I've checked the vendor section and found nothing. Anyone have information on what that would be priced (MoBo, trimmed finger pricing)?
Thanks
