I have used Multicore MP-100 and Heraeus F380 pastes for a while, and experienced very few dry joint problems. May be worth checking if the pad size and/or spacing are to the correct specification for the components. Check the date codes on the comp

1) The additional activity of the OA flux probably took care of the oxydation. How do you plan on taking care of the presence of conductive and corrosive residues from it now, though? You're not supposed to wash those parts with water. 2) The tomb

I have a mixed technology PCB that has SMT all on bottom, TH parts on both sides (Yes, I realize that's bad. Can't be avoided.) We have designed a 10-up panel, 2 x 5 array. There are 50 leads per bd, 500 per panel. How much time is reasonable to a

in your example, wool clothing and prairie winter ionization makes sense. Smocks would be an improvement to contain the potential of static build up. If you go to dress codes, then you run the risk of having to provide uniforms or pay a laundry allow

I have run into a problem when trying to produce a SMT PCB at college. Namely they don't have any equipment for such a 'modern' process. The part I need to use is JST 21FLZ-SM1-TB. Is there any prototyping equipment I could acquire which would allow

Does anyone have experience with different colors of solder mask. I am interested to know if a clear or light color mask is better in the reflow process. Most of the boards we do have a green solder mask. It seems to me that I read somewhere that

I'd be surprised if solder mask color is causing your delamination. We use various solder mask colors on FR4 boards and notice no difference. * ~99% of our boards are a medium green * ~1% of our boards are dark green * One of our boards is caramel b

If you considering selling the machine, it will have a much lower value, if you can't demonstrate that the machine is still operational. If you don't have any jobs for the extra machine, I would study the machine performance. Write test programs and
