Is there anyone who knows the yield rate difference for SMT on multi-flex boards and rig-flex boards ? Basically, I think the yield rate should be higher for rig-flex than multi-flex due to the poor dimensional stability of polyimide, since multi-fle

Electrochemical migration under conformal coating: That's possible. Very few conformal coatings are water resistant. So, if you have ionic material on your board, standback. Uncured material under several IC: Materials like yours need moisture fro

I believe on High Temp. Spheres you require paste eutectic 63/37. The solder paste forms an intermettalic bond to the pad and a bond to the surface structure of the high temp sphere. The standard 63/37 alloy spheres will melt during reflow and form t

Thanks Russ. When solder paste is applied, you can't see the pads. Because my aperture reduction is 5% - 10% of the pads. Pads are reduced by almost and up to 20% by the PWB Fab and the paste covers the pad. We cal align and inspect but very hard as

Wow, it's amazing what you can achieve with smoke & mirrors! Only joking. Does the original via hole covering solder get put on at the PCB fabrication plant, or by the customer? & Does the entire board get reflowed or do you have a process where ho

We have tried the vision both ways. Leads/body. Same issue. FYI Ken : The parts were not hitting the feeder pan on the back of the machine. I know this sounds really weird, but it seems that when we generate a program from Flexa(as opposed to FujiC

Mesh opening size may be a factor in whether or not the paste will pass but only in very fine line deposition. Generally speaking, the printed line width and deposition thickness determine what mesh to use. The paste supplier will be able to tell you

We are implementing an AOL inspection system into our surface mount process. I would like to hear from anyone with an opinion on the different types of AOL and why they feel this is better than another one. Any information will be greatly appreciate
