does it only do this with one assembly or panel config? i have seen this when the sensor shoots through a hole in the pcb/panel. the machine sees the panel come in, but it either overshoots or moves slightly into the open area. if i remember correctl

Yes, most of my fiducials are 1 mm. BUT, you may consider going 1.5mm or even better 2 mm because in my experience PCB manufacturers will NOT check fiducial shape during PCB testing. This goes for fiducials that are placed on panel frame. Fiducilas t

"For the lead free soldering of electronic assemblies, the inclusion of silver in the alloy results in better wetting compared to non-silver containing alloys and also allows for a broader process window. Silver also improves joint reliab

Also at few boards we see excessive voiding, extremily excessive. During solderind some bubbling can be observed near the soldering point. Boards was dried before assembly. May be we have a problem with too thin metallisation - that's why poor adhesi

Thank's Dennis. I'm also now think in this direction. Process was adjusted and soldering are good. But one from five boards can have this effect with bubbles and strange uneven distribution of solder inside the barrel. Probably copper is too thin and
