I've got a white spare PCB with ENIG. PM will follow.As the topic says, I'm looking for a unpopulated A3660 v1.1 PCB preferably with ENIG surface finish, . If you have one that you can let go please drop a reply or PM
In my subjective opinion, ENIG works better for reflow soldering.Hi,
I do have some blue HASL pcbs, and CPU sockets,
ENIG coating makes no sense as no unsoldered parts will be visible
