Hi,
This question is mostly for my curiosity .... I notice that the Proteus boards prior to 0.6 (and maybe 0.5, I don't have a 0.5 here) were finished in what appears to be HASL. The 0.6 board appears to be a gold finish, is this an ENIG or an ENEPIG finish? Is the gold finish only for the Tag-Connect JTAG connector, or were there other reasons for this?

Re: PCB finish
ENIG is both easier to solder and more corrosion resistant.
