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.
