>1) What type of gold and thickness?
Immersion (chemical) gold. Very thin I presume.
>2) Is there an underplate (type & thickness)?
Ni
>3) What is the soldering process specifics the board is subjected too (flux

Well, the had the same PCB in HAL. I'm sure they did not do any adjustments
to the solder machine.
>4) What are the board specifics (thickness, type, # of inner layers, hole
>dimenstions, etc.)?
Very simple 4 ML PCB, 1.60mm. In my opinion a D/S board would be OK.
