Need help urgently. Anyone can provide me some information or site on reliability test on PCB assembly like solder joint or anything. Some test like ERSA Test, SHMOO Test, Pull Test, Temperature cycle and humidity Test, vibration Test or any related

I'll try to get some pictures using the Ersa scope this afternoon. Not sure how to post them,may try to send directly to you.I'll take some immediately after coating then of the same after a flash off period.

azhiker, for me I selected method A. But I don't turn off wave and apply acid directly to nozzle with solder.

We been using the ERSA for a couple of years now with no problems. Guess I can't comment on the poor service as I haven't required their services. I sampled in all the units you mentioned, each was nice in their own way. One of the things that influe

Kurtz had a guy that was great with the machine. I strongly suggest that you watch the wave height test a few times in the morning then at lunch and at the end of the day. Look where the solder goes up to on the probe. If it doesn't work consistent

it's means that a pcb part responsible for second top zone is broken. To make sure i changed second thermocouple and heater with first. Now there is no overshoot. But I have still problem with automatically shutdown. It is turning off after 1 or 2

What is the proper storage and shelf life after washing a PCB with an OSP finish? We sometimes have to pull the boards off the line and wash the solder paste off the boards.

"We sometimes have to pull the boards off the line and wash the solder paste off the boards." Unfortunately I can't answer your question with any authority, but I guess my question in return would be why? Can you do something to address t

Or you can use the Hot Air (Hakko) to remove that component and a tweezer to pull it. dont pull it just yet. If you see the solder melting then feel the component using the tweezer by wiggling it a bit and if you can wiggle it only then you can pull

Problems like these are not caused by bad feeder quality. As described in the solution finding, the pull off forces of the cover tape are just too high. Cause is the blistertape and not the a feeder. Have you ever tested if the pull of force of the
