I have seen it all. from OEM that has 12 assemblies and the setup is always on the machine to a 5-6 setups a day in a CM environment with small quantities.

Thanks Mac! I have been doing a lot of reading and I think I understand me challenge ahead of me. I do however have a double sided assembly and the BGA's are on the second side. So I know I have to make this a quick build…. June

What is the base cost of an inline pcb etcher? Specs: fiducial alignment, smema interface, 400mm x 400mm marking area. Will be used to mark panel 2d codes, pcb array 2d codes, and human readable. Thanks Gm

We had this. The anti-backlash nuts were binding. We took them apart, chased the threads with a tap and re-assembled with slightly less pre-load. Hasn't been a problem since.

Typically when this happens the lighting in your package for a part in one of those cycles has 0 0 0 in the 3 light settings. You need to check all your package types that are used in your program and makes sure they are adjusted correctly. Good Luc

Hello all, what is your opinion on step stencils. Is it better to have the step on the squeegee side or on the bottom side of the stencil? Why you do it this way? What are the advantages and disadvantages?

I think you need step on the bottom side of the stencil (undercutting) only to compensate elevations on the top side of the PCB, such as labels.

Not an expert, so bear with me, but I think that depends on how much components are in the vicinity of the pads you want to step. Hope this pdf helps Cheers!

I always put the step on the squeegee side. You'll get some "shadowing" effect on any parts in close proximity to the stepped up region. It should be manageable with proper board / stencil design.
