| | | We have a new PTH board that utilizes lap pads on the B/S. Some of the pads are paired closely together and are aligned at angles (30,45,60 degrees)to the boards direction of travel through the wave. The pads most always bridge together. I rea

Is there anyone that makes a pick and place glue dot for surface mount chip components (B stage epoxy dot in a carrier tape)? Thanks, Rich

Tough call without seeing the board, but here's my best guess. You don't say if the glue dot is greater in height or diameter in the locations where you have printing (silkscreen), but I would guess that you might get either, or both, depending on ne

We are assembling double side pcs reflowing (smt) on top and by wave on bottom. After first step (smt) we dispense glue on the bottom side putting one or two glue dots under small components and we cure in oven before wave. After wave soldering we f

Specifications of testing force are not fixed, but (incase of wave soldering) the value should be at least 120-150 % of the force the wave. So for small chip components we assume that the force from the wave on the component is about 3 Newton, this m

Crappy piles? Weren't they a hard rock band in the 80's? I know on most of our boards the little silk screen dot is just the component identifier in really small font when looked at in Gerber. But this dot isn't very big, so I see how it can affec

Why? Sounds like a Band-Aid. Are you screen printing of dispensing adhesive?
