Not now, Valor may under develop the module for its Trilogy 5000 with the stencil aperture based on the rules which you set. Also, check with IRI stencil (Alpha), they have a s/w and based on using ODB++ file and not Gerber. Rgds.

Are you talking about selective wave pallets? Most of it depends on the minimum thickness of masking walls (design). I have had some that have lasted until the product went EOL (5000 passes or so. and some have made it about 50 passes. How's that
