Sorry to build up your hopes. The latest thing to hit the air ways at work, I was accessed of fiddling with the oven settings, because there were reports of "cracked joints" there was no mention of where the cracks were, cracked at the pcb or cracke

We've had similar "disputes" with our quality department. A technical engineer from Nordson told me that the flourescents in the coating can look faint depending on the angle in which you look at the surface as well as how solder joints reflect the

IPC-J-STD-001E in regards to Ionic Cleanliness standards states less than 1.56 µg/cm² of total NaCL. Assuming a typical electronic process which involves smt, wave, and post-hand soldering and uses NO-Clean flux throughout all process, is it typi

If you are a CEM you are setting yourself up for failure and will be left holding the bag. Flash gold has one purpose. It is a protective coating for the base medal to keep it from oxidizing. It is very thin and will be absorbed into the solder joint

Thanks for the comment regarding the CPH. In fact, the benchtop oven we have takes 7 minutes to complete a batch soldering, so you can imagine that our production volume will not be very high. We can parallelize PCB assembly and oven phase. But defi

Sr. Tech, As far as I’m aware, most if not all, manufactures of thermal profilers offer K type thermocouples as a standard for profiling in the electronics manufacturing industry. In my decades of experience in the reflow and wave solder industry, t

We are thinking of getting a small pcb assembly setup for a small manufacturing co-op here in Los Angeles. Our experience consist of manual soldering of through hole and smt components. A quick search suggests that there are a few turn key opt

But where does it go, that it needs to be refreshed or replenished on the stencil? Does that "just like wax" product wind up in my solder joints, no matter how small the percentage, and would it then qualify as a contaminant? I heard there are some (

Assuming your conformal coating material was selected with the intent of living a life in contact with oil, why doesn't your coating meet the IPC-A-610D requirement of that there be no voiding, no breaks in the surface, no loss of adhesion, etc? Furt
