We haven't laser engraved PCBs but we have had 2D barcodes silk screened on. When I saw them I thought that they would not work because the white squares were blobs but they did work. With the Datamatrix format only the centre of each little square

Hello - I have seen this work effectively with a diode laser. I recently purchased a CO2 laser which I am certain would work. 10-20w diode lasers (used for marking and engraving) would likely work. The resist burns away, but the copper then dissipate

Perhaps your stencil supplier could laser mark the number on the stencil. This only helps from here on. How about engraving the numbers on the stencils you already have? Engravers are pretty inexpensive and shouldn't damage the stencils.

You could also try something like a Radian desktop fiber laser as a smaller, low cost alternative to accurately and permanently engrave each stencil frame!

| Has anyone used the mechanical stencil foil tensioning system from certain company that eliminates using stencil frames and epoxy & mesh? Any comments on whether it's worth looking into? We go through product revisions like we go through clean so
