Your customer forgot to apply solder paste to the PCB ?

This doesn't sound like a solderability issue. It sounds more like nonwetting.

I am sure that you did a reflow profile.... right ?

My factory produces Printed Circuits Boards.Today, my customer says they encounter problem with solder ability issue. Some of the boards have difficulties during SMT solder flow. Could not stick to the pads and the components fell off. Those boards

we are manufacturer of molded type transformer. we have a trim and form process and its damage the pins of our units. the TIN insulation was being damage so we decide to immediately solder (wave soldering) the units to avoid oxidation. my question is

Hi Arnold, Some wave solder machines have a preheat function, that raises the board temperature before soldering. Some transformers use single use thermal fuses/TCO's inside, that trip at a set value (in a range approx. 70 degrees C to 180 degrees

If the component "fell off" sounds like double sided reflow - which is most likely a profile issue. If the parts just don't solder, could be many variables. I've had supervisors accuse ovens for bad profiles cuase they had missing parts. Too bad

We have been having a solder paste reflow issue which results in the solder not wetting to the LED lead. The solder appears to create "puddles" on the pcb pad. I have attached AOI image for review. We have had the pads analyzed for contamination, w
