Laser Stencil For SMT Solder Paste PCB Assembly Stencil Shim

1.1 General description

This is a type of solder paste SMT stencil (100% laser cut) built on 0.1mm stainless steel foil with aluminum frame 520 mm x 420 mm x 20mm dimension. It’s fabricated per IPC 7525A using supplied Gerber data, squeegee area locating in the center. Fiducal marks are through holes to suit for the SMT machine. It’s packed with KK carton (hard card) and usually 2 stencils are packed for shipment.

1.2 Features and benifits
