Hi rob, Thank you very much for your response. Profiling was made exactly on the pad, which showed dewetting, so the values are mentioned for this pad. PCB's is about a week old. It is possible that the surface of pads is already oxidized? I will t

For selective soldered components, or even hand soldered, with vertical bend components, the body of the component, in this case a resistor, is making contact with the surface of the PCB, making it impossibe to visually see the solder fillet. Or to d

Aperature layout on your stencil could be a root cause as well. Home plate design aperatures have cleared this issue up for me in the past. If it's a clean product, running through the wash may get rid of quite a few of them. Also check your IPC s

Have a problem with TRM-03. Today, after "RAM-error" message, my TRM-3 became a TRM-1 (on display). Menu is almost empty, but the biggest problem, that the middle segment is not working together with first and third. PCB is just stopping before the m

Hi, we do that for some of our assemblies(the only difference is that our cut in the PCB is bigger and the LED leads step on the paste right away). we place these manually. I assume that you can send them for tape and reel, and if they can find the r

Perhaps a photo of the faults you are encountering might shed some light on the issue. I would think it would take some extremely poor paste handling or paste for the paste itself to be the root cause of what you seem to be describing. I would be inc
