Hi Yannick, Smart Sonic has just introduced the "Assembly Module" to their StencilScan AOI software package. By adding the Assembly Module to StencilScan AOI, one workstation allows you to inspect and compare the stencil to the PCB and Gerber data a

Read IPC-7530 "Guidelines for Temperature Profiling for Mass Soldering Processes (Reflow & Wave)". There is no advantage in dropping off much faster than 4�C/sec. In fact, you risk fracturing your newly formed solder connections due to board warping

Never heard of flux residues forming a lense. The first thing that comes mind when thinking about your 'fog test' is: Ionic Contamination While this seems pretty far afield from your interest in optical effects, I'll continue briefly. A reverse
