After doing some more research it looks like Loctite made a material called Cornerbond 3515 that seems as if it has the characteristics we are looking for such as curing after the solder is liquidous. But it appears that it isn't manufactured anymore

hi, i am proccess eng solder wave process.I have problem with a PCB.There have ceramic SMD capacitor, SMD thermistor and SMD inductor 1uH.After reflow all is OK, but after SW these components are broken???The pin is separated from the body???the que

Makes us wonder how well the connections on the > component match with the pads on the board. The pads are actually larger than the leads on the part, but I think we may have figured it out. We believe the conveyor vibration is causing it. When we

Theres something to be said for having a machine operator or inspection person carry the board from the output to the oven. Id say about 1/2 of our issues are fixed/noticed in this simple step of transferring the board from the PNP to the oven. If

Thanks for the reply, how do people handle different packages then if you can't add new ones? If we had a 1206 sized inductor, then a 1206 sized ferrite bead and so on, they would all have to be grouped under the same generic heading? e.g. Chip-R321

Hi all, Long shot but worth a try, I am trying to identify ref: L1 Inductor which is on the back of the above mentioned cognex card ( green camera Dek GSX265 machine). Card functions fine but doesn't output any video - L1 is blown on the back whic

troubleshoot rfi ... for advice. Bottom line: I don't think staking your "inductors" to the board will alter their performance. Continuing, I don't think it will fix your problem, either. Bonus comment: I'd talk to a board supplier app engineer bef

Have you tried rotating the board 90 or 180 going into the oven? With inductive components there's a possibility of magnetic current buildup, that pulls the component to one of the pads. Although, I've only seen it on larger inductors. Also, the pres
