When choosing materials, do you specify your thermal PCB needs? For instance, are you specifying temperature or are you selecting materials by brand name?

The main question is, where is the problem: With the piston, in which case I can use some air oil on the rod or even a small drop in the air tube. OR With the mechanics, specifically the sprocket in which case I am not sure oiling only without prior

There may be supplier guidelines or accepted practice, but there is no shear specification for printing either paste or glue. Beyond the issue of not knowing the shear value, what's the problem that you see when printing glue?

Compared to 63/37, solder with high tin content: * Requires higher reflow temperatures * Demands tighter process control * Results in duller, more grainy looking solder connections Tell us about the specific problem that you seek help in solving.

Not specific to QFP, but I had a run of poorly etched boards. I could see the short using 75X magnification with back lighting, but only some of the time. Nasty little shorts on ~25% of the boards that cost us a boat-load of cash.

Have you moved this LED to a different dispensing head? I have seen some dispensing heads that are out of adjustment cause the same problem. Jerry

I look for specification for degolding - pretinning for SMT and through hole parts (in the military sector) . I found IPC JSTD 001 and some ECSS ...08 but without visual real criterias on the product. Thanks for your inputs .

IPC-A-610D Sections 3.1, 3.2, and 3.3 and Table 3.1 specifically mention compressed air as a source of ESD damage
