Hello, I am looking for some info on the Camalot system 5000 liquid despensing machine. We just bought one used and I have no idea how to use it yet. I cannot find a web site for the company. Any help? Thanks, Tony

They probably the same. Most likely someone is saying immersion gold [immersion Au] as a short hand for ENIG [ Electroless Nickel - Immersion Gold]. It is very uncommon to plate gold directly on copper, because gold and copper form a brittle interm

Can�t help you with the article that you read. Other places to start are: * 2221, 7.2 Heat Dissipation Considerations, 7.3 Heat Transfer Techniques, and 8.1.10 Heat Dissipation * 2222, 9.1.2 Thermal Relief In Conductor Planes

Several of the points you make are reinforced in the fine SMTnet Archives. Consider searching them for bedtime reading, until the responses start flowing.

Kinda makes ya wonder why ya changed, eh? Some of our 20 pitch HASL boards come-out just as flat as a farm pond. Just got ta letum be. Pete is spot on!!

Almst quality of PCB with this pitch defined on used boards. Good board produses Fullmarks , look up to it , stencil parametrs isnt so critical but board material and layouts.
