I�m suddenly getting a very high failure rate in a TO99 component (National LM136AH-2.5). After some investigation we found some of these parts are more than 20 years old. What I am hoping for is that someone out there can help me find some standards

The two first level cuts at comparing placement machines are: * Placement rate * Range of component capabilities This boils-down approximately to machine price. Virtually, everyone's feeders are priced similarly. Go to "Circuits Assembly" magazine

ENEPIG or Imm Pd? Concerns about palladium as a solderability protection are: * Palladium is more difficult to process in fab than gold * Palladium solder alloys can be brittle, similar to gold, without proper soldering process and/or specification/

One important thing to look at, when buying an AOI is the False Calls Rate, along with tact time of machine to inspect the PCB. Obviously, many machines can do the the work....but it's also true that each machine differ from the way it do the work. S

"thomas, why isn't it process control," Minute detail, really. Defects aren't a measurement of process parameters, they're the result of them (and a few other things that have been mentioned). SPC measures process parameters. It is preemptive, and

What we have had recently is a lot of larger thin (32 thou) thickness boards that have had issues with SC90 diodes bouncing off the pads in the final PNP machine. Our setup, universal instruments GC120 or quad beam 30 spindle lightning heads. This m

As I was explaining in my thread, the things that you have to look for when buying an AOI is the false calls rate (which you described perfectly) vis a vis the money and time you want to spend. We bought our machine after that we evaluated some. As y
