PCB manufacturing consists of many steps, such as PCB CAM, Panelization, Copper patterning, etc. This group is mainly talked about the problems during PCB manufacturing!

I have a panel needs , and I place three fiducials on each pcb for a plane needed fiducials. But some IC footprints also show local fiducials. I've seen them for instance for certain TQFP footprints. When are they required?

Fiducials are used to provide better accuracy when placing components on the pcb. There is a camera that recognizes the fiducials and uses it as a registration point to calibrate where the machine thinks it is on the pcb.


BGA devices often used fiducials, because the pads can't be seen when the chip is placed in position manually. I don't think I've seen them used with TQFP parts.


A great sharing for beginners. Thanks for your efforts and I will follow you and keep reading your posts.
