hello, has anyone tried dispensing solder paste in thru holes instead of waving or hand soldering. if so how did it work out for you. thanks for the input wayne We have tried this mainly

Wayne, Earl, I wish there was some way we could toss our wave solder machine forever! Unfortunately, we haven't found a way yet to do paste-in-hole reflow for large numbers of thru-hole axial and radial components, which we insert on Universal machi

Air inclusion in solder paste

Thanks Dave I'm not convinced the air is necessarily in the paste from manufacture - suspicious that it may be folding in during the change in direction of the print cycle - or as the paste travels across apertures. It is not necessarily in the fir

Hi We are running automatic stencil printers, open squeegees, stainless stencil, stainless blades, print speed 25-30mm/sec. We have a frustrating consistency issue printing .37x.3mm apertures on a 45pin LGA (11 pads each side, 1 large ground in mid

200 pin connector reflow

You can try putting titanium stiffeners on the PCB to prevent it from warping. How thick is your stencil? More paste would give you a wider window however too much and you risk bridging. You could try over printing the pad at the heel and toe to get

200 pin connector reflow

Electronics Forum | Thu Nov 07 21:28:31 EST 2019 | sssamw

The connector is so long, and has big metal parts, it will be little deformed during reflow I guess, andthe pins planarity should be critical for 200 pins. Did you measure the non wetting pins profile to see if temperature ok? And maybe you can try u

Experiencing a problem with a 208 PBGA device. I am achieving good wetting with the exception of one ( damn) pin on the outer corner.I have a really good profile but the worrying thing is that it is so inconsistant. Once this open pin failure is dete
