Are you gluing these components by chance? I had an assembly where a glue dot was slightly too big and it pulled to the outside of the components solder joint. This looks eerily similar.

Understood, but I do not think you will find anyone who gives a standardized rule across all components. Different components will have different restrictions. At a minimum you need to determine what is the most sensitive component on your BOM and a

This looks like it could be related to oxidation.Do you per-bake your pcb before assembly to remove any moisture inside your board panel?

I don't know why you would NOT use a no clean paste. You're just adding time and cost to the assemblies, not to mention potential problems. Changing paste is the best option here unless you have a very compelling reason not to.

Depending on the assemblies you're producing, I highly recommend 8.9HF from Indium for a low residue SAC305 alloy. We have been using this for years in our NC process and residues are very little, with appropriate stencil apertures and paste printing

Looking for recommendations for an SMT supplier (both SMT and through-hole capabilities) in the Greenville, SC area. The product portfolio is high mix, and low volume. We would kit/supply materials, so we are only looking for assembly capabilit

Most of our LEDs are assembled as individuals connected by PCB traces. The ones that aren't are triple LEDs with three colors.

We make PCB assemblies for an RGB arc that is made up of multiple curved PCB's that have connectors on the ends to plug together. I think the end the radius of the arc is 2 feet. Jerry

Find out were the excess flux is coming from. See if it can be eliminated or reduced at the source. Lokely coming from something other than SMT assembly.
