The paste you dispense will not solder the same as the one you use with a stencil. The paste for the stencil will have a higher metal content. I was not working with dispensing as small as you are, but after evaluating the cost of the stencil vs. lon

Our customer ask us how many repair (component removal, change and soldering) we guaranty for SMT components on our printed wiring board. We all have the number "3" in mind but we can't justify it by a standard. We can't reply "state of the art". Doe

Thanks everyone. I have thought about the moisture in the paste a lot, but never really gave the raw card moisture any consideration. The next time we run an assembly with the issue I will try baking some of the cards once the issue shows up to see i

Dear SMT Manufacturer, I am wondering if the device could have so much moisture in it and storing it in a dry cabinet isn't going to remove it all. As a final test to see if moisture in the device is causing the voids/solder balls then I'd bake it a

Manufacturing-wise, is there a problem with doing a single panel with both four layer and two layers designs on it? I do prototype runs with multiple designs on the same panel, and I'd like to start including four layer. It seems to me that I can g

I've seen the purple silkscreen before on ENIG board built with PbSn process. I would think that if temp is the issue the lower process temp would not have caused the purple ink. I remember that the flux I used was water soluble and I attributed th

We are a CM looking to do some low volume taping for the purpose of getting some undesirable parts out of track feeders. We don't always buy in the volume to get reel and it seems some components ie.Maxim only seem to come in tube. Is it typical for
