Product profile
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
