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.

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

In a previous lifetime, we had a selective solder machine where I would see solder splashes in the roof of it. I thought someone might have been putting the solder extremely high. But when it was melting there would be bubbles that burst. The manufac

Blew chunks - thanx for thinking outside the box. Of course there's two sides to every story. Just last week I had a new operator "splash" a couple of boards. Top solder was great, it was all one big solder bridge. Come to find out, the operator forg

We're trying a selective soldering pallet for the first time with mixed reviews. Are solder balls a prevalent problem with this process? Most of them seem to correspond with pallet wall locations....is it too much turbulence from the rotary chip wav

We are using Vicor SMT J-Lead VI Chip which is big component on the bottom side. The manufacturer recommends to have 6 mil stencil but the customer required 10 mil stencil. The PWB has gold contacts on both sides. We noticed some mini solder splashes

Also, solder splashes can be due to contamination, for example, on the terminals of components. In the past, had a problem with solder splashes on a seemingly standard SMD component. The reason was the incorrect nickel plating process of the componen
