Good afternoon all, I have been trying to find a solution to a defect I just noticed. After stencil printing and smt part placement on the secondary side of my boards, I run them through a wave soldering system. All my components got soldered perfe

Thanks for your reply. This production lot is already finished. We produced in 2 lots, first was no-clean (and was ok), 2nd lot was cleaned (aqua based), and I need to look into the cleaning further. Since it's all finished I can't get parts from se

In general, if the process has been consistent for a period of time, then one should look at any new variables in the process. Therefore...the supposition that there's a bad lot of components is a very good one. Did Yageo offer any possible explana

Sean, We can't comment on the EDX report; but, we have seen these types of problems before. We would initially agree with you that it seems like a material issue. A solderability test should be performed on the part, and on the board. Easist way

There are several things that can be done. Shortening the lead length should eliminate bridging between lead. We had done a project several years ago where the customer had shortened the leads to almost flush to the board, preventing any chance of

I hope I understand your question, but are you saying you're having trouble meeting demand? Keep a log of the time that the machines are down, probably for 4-6 weeks would be good and this may give you a good idea of what kind of downtime your worki

In my experience Through Hole equipment normally racks up the downtime due to the amount of process variables. For SMT you would normally try to capture your workhorse machines Utilization. For example a chipshooter inline with glue dispenser,screen

I placed almost nothing but 0402 components on the Contact 3AV and 3Z machines I had. I will admit that there are better machines for placing 0402 components. Not sure why the 3AVX would perform poorly at 0402 placement. The feeders have a X & Y a
