I know that on Philips Topaz equipment you can define the XY locations of the individual local fids relative to the mount-center of the component that they apply to. So if they are not symmetrical w.r.t. to the QFP's center there's no harm done. You

That your problem is not related to component solderability or wave process related makes us believe this has to do with bare board design. Look at how your designer did the thermal relief on the two pins that don't solder well. If you can't get a

Dear Pro, I want to confirm with you about conveyor speed. is 1m/s? We are using wave soldering but it is 1.2m/min, min not second. Pls, check it agian. The flux is not relative this error. It is relative no sodering, bridge. The solder bar is the

Somebody feel free to correct me if I am wrong, but I would say that flux pressure should be related to the PCB width and desired flux deposition and the sprayer speed should be a function of PCB width and conveyor speed. Basically, flux pressure af

Which type? * Solder beads (mid-chip solder balls, attached to the waste line of your chip caps and resistors) This is more paste volume related. * Solder balls that tend to be more randomly scattered (as in spattered)? This tends to be more profile
