Hi Dave, Thank you for your information. How about the glue print on PCB and not mount component, what is the idae to inspection this glue is suitable for mounting component. For example insufficient glue excessive glue. Because we found the problem

ah ... but we had insufficient heel fillets in the old design toom when we had more pad area ... just not as bad

You also would want to talk with your flux supplier. They are usually knowledgeable in the proper application of and heating of their fluxes. Usually, insufficient solder in a wave process is related to insufficient preheat,dwell time, and flux app

We are encountering insufficient solder paste. Our stencil thickness is 0.13 mm and our printing pressure is 0.08 MPa our solder paste is Tamura TLF-204-19A. Please advice how to solve this problem.

Selective Soldering Frames can pull large amounts of heat from the solder wave at the point of contact, effectively lowering the temperature of the solder at the solder joint. You should confirm the temperature of the solder joints by running a therm

Consider posting actual measurements of your pads, component leads, and apertures.

The XRAY looked okay with minimum voids throughout. Customer reports insufficient contact causing intermitten failures.

Sounds like you're talking about the "heel" of the lead not being soldered, in other words, no heel fillet, which IS necessary. That problem, for us, was attributed primarily to poor layout (insufficient length of pad extension to provide room for
