Hi Emmanuel, There is lots of info. in SMTNet archive (I think 98 Sept-Dec). I had a lot of problem with PBGA and certain uBGA with their PCB base material (FR-X) and encapsulant. Wolfgang is correct. We had to reprofile our reflow oven , qualify an

Casey, I will start with the lack of thermo-couple control - The unit I have is based on time and temp. exclusively. What happens when a cold board gets reworked vs. a hot board? No bottom side preheat, the heating is very localized to topside a

I'm looking at stencil printers, particularly those that can produce good repeatable prints on finepitch boards with minimal setup and training. I would love to find a printer that does auto x-y-theta alignment (would like a system that aligns sten

Hey!!! Watch it!!! I don�t want to get you believing too much of this stuff. But if you bought that, listen to this � some circuits are so critical with that skin effect stuff that they use silver as the top level solderability preservative. Turn

measuring Paste volume or at least paste height is an essencial part of any SMT process. You've got to control those input's.... Paste volume determines how much solder is available for your joint so theres a direct to joint reliability / PCB reliabi

Yins are bad, this guy's serious. Generally, solder pastes are comprised of: 90% solder powder, 5% flux, 4% solvents, and 1% activators [by weight]. Where: * Solder powder, when reflowed, is a metal bonding agent that mechanically and electrically
