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.

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 there. would it be possible that thermal relief pads for relay bring bad solder?

Hi SweetOldBob, how did you say then?

Are your solder relief pads connected to anything in terms of ground planes that would increase the thermal load or are they floating copper? I take it your talking about wave solder relief pads?

PCB Supplier made an EDX anaysis, the found a chemical trapped in the holes, and some burnt burrs, according to what they say this stains are over the solder mask & silk, so they do not affect functionality.
