Hi fellow professionals, Wondering whether anyone has experience with solder splashing from component terminal. Have identified the source using the component without printing solder paste on PCB. Wondering the root-cause of the solder splashing fr

Could be that your temperature ramp up rate is too fast. This could cause the flux in the solder paste to burn off too rapidly. When that happens, it can expand as it heats up and burns off, causing the solder to get spread out from the pad.

Thanks for input, dyoungquist. The condition here is without any flux or paste applied. Solder from component terminal started splashing by itself when put through re-flow.

Hello Henry, I believe some further clarification may be needed for someone to assist. Is the component already soldered prior to reflow? Does the component have paste already applied going through reflow? (or as per my previous question, is it al

Hi, We are facing solder ball problem in manual soldering process (between wire and terminal). we are using no-clean solder (63:37)and temperature setting in iron is around 400 Cel. Can any one suggest me how to solve this problem Any thoughts would

Would be glad to offer some assistance, but I've got a couple of questions first: 1) What type of supplemental flux are you using? (If any) 2) Is your problem consistent across all assemblers, or can you trace the assemblies with solder ball issues b

hi Team, observed excess solder after assembly jumper with manual solder method. I already try to duplicate the phenomenon with adding more solder tin/wire,adding more time for solder but not found same condition I have attached the image for the

Would like to know what type of soldering iron you are using. On this type of big jumpers, a continuous heating soldering Iron will do the job nicely in order to heat the jumper wire properly.

I think Steve is on to it. The wire is not getting hot enough to wet. Either the solderer is attempting to solder too quickly, or the PTH is connected to a ground plane. The solder sticking up through the hole leads me to think it's connected to a

It doesn't look to me like the jumper wire is wetting at all. I would immediately question the solderability - do you know how that jumper wire is finished (plating type)? Also, how experienced are the solderers? It could be that the wire never get
