I'm looking for test labs in Taiwan that are capable of performing ionic contamination testing on small to medium sized SMT boards. I'm interested in both ion chromatography and ROSE test methodologies. Is anyone aware of any labs performing contami

The main function of the test is to evaluate the solder mask. Basically you are testing three samples: #1 - No solder mask, #2 - solder mask without solder, and #3 solder mask with solder. The solder pot is used to apply solder to the patterns on O

As always, our good colleague Evtimov is right about the AOI and oven. For the AOI you need to make a golden sample board(panel) and test if your machine can catch all defects that you simulated BEFORE the oven. Try to me as accurate to real defects

Hi, I need support on the method or applicable standard to measure the shear force strength on chip capacitors and resistors. I know the soldered joints strength is related to land desing, solder volume, pcb and component solderability, component

Thats the one I found while researching this AM also. Thanks for the assist. Any ideas if this can be process related? Im sure it can be but its odd that it only happens on one vendors board. I think because it is an 10 layer board that maybe they ha

Hello all, we have been seeing a lot of issues with broken or open vias on a couple of our bare boards. We have two vendors make these for us and the issue is only with one vendors boards. We have stopped using them until we can figure out what is go

Maybe there's no test and I don't know where or why my customer came with that requirement (I think because in one of the board shipments he got a board were a smd resistor broke, but I think that happened because miss handling), but anyway I need so
