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

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

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

I'd like to know if anyone could recommend a good high-temperature adhesive that can be used for thermocouple attachment. I've always used high-temp solder and tape in the past, but would like to try using adhesive. Any info is certainly appreciated.

We have always had success with light cure adhesives for probe attachment. Try these guys for some samples. http://www.dymax.com

Roger Saunders, President Saunders Technology, Inc wrote a fairly unbiased paper that compared different thermocouple attach methods. You can probably find it on their site. In it, about gluing thermocouples, he says: There are two general classes

Hello Fredrick, I have used several methods of TC attachment including quick set adheasives (not good at reflow temps as Dave suggests) long set two part epoxies (work well if you have the time to wait for a sufficiant cure) temprobes, tape (kapton
