May be you right, but I spend a lot of time on Technet (a similar site maintained by IPC) and people who posted questions usually come back saying whether the problem has been solved, as someone else may face a similar problem down the road. I think

"I 100% agree that quality engineers can and do solve a lot of problems on the spot." *cough* *snicker* Or did you mean "engineers of high quality"? By and large, the QE's that I've worked with only found, identified, highlighted, or conjured u

Do those Balls pass IPC LOL Looks like the paste has been stored incorrectly probably stored stood upright and the flux medium has 'moved' so you have very rich flux areas and getting slumping due to it. Paste in cartridges should be stored flat refr

ISSG, I didn't see you mention anything with respect to profiling. Should we assume that you've already ruled out any thermal issues? Based on the proximity of your problems to a big honkin' connector that's where I'd have looked first. But then a

To have an Operating Temp (Tool Classification) within your range, you might want to try. PB85 (Pb85/Sb10/Sn5) SMT is normally processed using Vapor Phase but can also be achieved with Nitrogen assisted Convection Reflow depending on size and compl

Yes I have a KIC and have checked the profile often. I just changed the reel of the parts that are causing problems and it went away. Now what am I suppose to say? I have made an NCMR for the parts but I'm sure they would work in an environment of

Hi Joshua, We ran 150K per week this way, you just need a lot of pallets. Regarding dispensing I've seen 0201 (Imperial)paste dispensed, so about 0.4ish mm dots. I'm sure the Mydata printer is also pretty high resolution too, but not too quick.

Hi Joshua, No, the adhesive lasts 2 or 3 runs. The adhesive is put on manually as is the kapton. It's a big panel for a flex - nearly 300 x 210, so the operator loading the boards onto the pallet and fixing them (then into a buffer) stays well ahe
