I think that the IPC spec only apply to the MSD. I had a paper from Lucent and forwarded by Francois Monette, please aware that the first 2 hours, the moisture doesn't bake out from the assembly/component and result show that it is increase the weigh

Hi Guys, thanks to everyone for their help and advise! we are running these LCC parts in the 1000's, so its going to pose a big problem to either: 1) tin-plate the oxide layer, 2) HCL away the oxide layer, thanks for the option shown, dun think so

First off what bone-head designer put them there in the first place. Vias in solder lands is a big time no no. I had this problem at a CEM I worked at. I had the customer change the design but had to run the 6 samples they supplied. I ended up fillin

Greg, As Dave pointed out, the main reason to bake components is to remove absorbed moisture from moisture-sensitive components. All you need to know on this subject, including the specific bake conditions (temperature and duration) are clearly s

Hi. Does anyone out there know of a way to calculate the surface area of populated PCB's? We build many different types, and until now have been using a water displacement method, which I believe to be fundamentally flawed. Our technique is to drop a

I think what David was getting at was, as an example. Take a cubic inch of gold. Surface area = 6 sq/in. Volume = 1 cu/in. Water displacement = X. Mass = Y Roll that cube of gold out to a micron thick. Surface area = football pitch. Volume = 1 cu/i

This conversation reminds me of the old �How Many Engineers Does It Take To�� joke. We manufacturer the ionic contamination (ROSE, SEC) testers and I am not aware of anyone that performs such exacting surface area calculations. Most people use th
