I agree with Iman. Verify the integrity of the component for moisture. Most definately place an amount of ownership on your PCB supplier. Request tank analysis results and copies of the lot travelers. Look specifically for any in process rework pro

Dave, thanks for the info. This sounds like it would verify the presence of an open. We have verified that these balls are open and I am trying to figure out if we are fracturing or not wetting. causing these opens. I would use the die method on ne

Hi there. We are considering to attach die chip with solder paste to the pcb at the SMD line (we are used to attach it with silver epoxy at the die bonding line before). This is a whole new method to me, so I'd like to have some opinions here. Where

Sam We install a lot of die in the SMT room using same process as SMT parts.Water soluble solder paste is used for attachment of die to ceramic and boards. Biggest problem i found is the adjustment from installing the die in the bonding area. The t

Yes, some testing of soldering chip capacitors onto ceramic substrates with high temperature paste proved successful. Die attachment can be achieved using this technology as well. The underfill of the die becomes a critical factor in rework potentia

What to you consider to be the minimum resolution [micron] for: General, BGA, die attach uBGA, flipchip, wire bonds Wire cracks, delamination Microcircuit failure What is the relationship between resolution [micron] and the kV of the tube?

Rob, I believe that is for die attach voiding not solder interface.
