I guess, since nobody is using local fiducials anymore, we forgot how to program the fiducials. Was it in the component-package file or in the placement file? Nevertheless, once you find the place, where you enter the fiducial position, you'll find t

We took Orbotech and Viscom into short-list. Both systems uses angular cameras to inspect solder joints. I'm also very interested to hear any experiences and posted the ORBOTECH vs. VISCOM message some days earlier.

Your broad question will bring many answers.You do not mention PCB type which plays a key part in the inspection specs you look for. Your question is like asking "What is the best automobile?" You will have 1,000,000 answers. Best answered this way:

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 realize th
