>Hi Jens - We need some additional information to help provide you possible >solutions: > >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 >type, conveyor speed, etc)? 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. Jens Behrens > > >Hi All, >I got a problem with solderability! >We where selling a HAL PCB for a few years.
