What is the board finish? Did you profile built assy and get the temps on the board with a t/c in the board? DId you drill the BGA and get the t/c at the ball? When the parts came off the board did all of hte solder come off the pads and stay with th

J-STD-001, 5.4 Solderability Maintenance states words to the effect "The manufacturer shall ensure that all components [bla bla bla] are solderable at the start of hand and/or machine soldering operations." So, how many you contractor cats 'n kittie

Hi to All, I have bought my CSM66 ~3 years ago. It has a not too user friendly interface... :-( But fortunately it has a great possibility to upload files via RS232. So I have created a simple excel sheet to build those tricky BRD & FDR files. Here

Our Hellers exhaust has a range from 500 to 600 CFM, depending on model. I am aware that the profile will need adjustment due after reducing the exhaust air velocity, but i'm not getting a reply from Heller for power consumption specification. I will

Interesting, thanks for the info. All that I know right now is that running the jaws through an "el-cheapo" demagnetizer was one of the actions taken that resulted in a reduction of missing components. It is possible that this is not a dominant fac

Im not sure if someone has posted this topic before. Anyway,we plan to make capability study on our wave-soldering machine but we have no experience on how to do it effectively. My question is what we should consider most among the critical parameter

WRONG! Actually I was going to say the same thing but figured I would have the standard 3 people dissagreeing with me, and or correcting me. I do believe your wave solder temp should remain a constant temp and prolly will not vary at all, so I woul

Hi BR, Are you screen printing adhesive to the bottom of the board? If so, have your stencil make put openings between the leads of the thru-hole part. SMT adhesive acts as a natural solder resist. So placing a small sliver between the pads works

Thanks all! I'm facing this issue with one specific batch of QFNs. It could be a plating issue. But, nothing was evident from visual inspection,No sign of voiding or non-wetting. Cross-section images of solder joints were clean as well. Could this s
