All stencils are precision laser cut on stainless steel steel "shim" or "foil" material chosen for optimum hardness and polish.

If stencils with frame mounting patterns are required, together with aperture editing to optimise solder paste printing on production runs, use the laser stencil full service, do not use the Express Stencil service. Ensure we know what frame tensioniong system you require. We regret that we cannot supply stencils mounted on fabric stretched over aluminium frames.

Express stencils are shipped on the next working day following the working day of order placement. Express laser stencils are suitable for all component pitches down to 0.4mm (0.016") and all discrete components down to 0201s.The profile of the Express laser stencil is cut to the size of your PCB with the addition of a plain border of at least 10 mm on all sides.

Note that all Express stencils are supplied without any frame fixing holes or fiducials. It is assumed that paste data files will be 1:1 to your PCB pad data. Express laser stencils will be cut with standard feature reductions of 5% from your PCB layout data. If top and bottom stencils are required, request 2 stencils on the order form and pay the lot price for 2 stencils as quotedpads.

If your PCB has been ordered in a standard PCB Train step & repeated panel, then we will step single image paste data to the same pitch. We guarantee that the stencil will register perfectly with your PCB panel. When ordering such stencils, enter the overall "x" and "y" dimensions of the step & repeated panel in the Express stencil price calculator.
