PCB SMT Stencil Built on 520 X 420mm With Aluminum Fame
1.1 General description
This is a type of laser cut SMT stencil built on 0.12mm stainless
steel foil with 420 mm x 520 mm x 20mm dimension. It’s fabricated
per IPC 7525A using supplied Gerber data, squeegee area locating in
the center. 4 sides of 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
The data file is used directly to produce and reduce the error
rate;

whole process error is ≤ ±4 μ m;
The opening of SMT template has geometric figure, which is
advantageous to the printing and forming of tin paste;
ISO9000 certified manufacturing factory;
12 hours quotation;
Quick Lead time: 1-2 days;
No MOQ, low cost for prototypes and small runs quantity;
1.3 Application
SMD package such as PLCC,QFP,0402,0201,BGA,Flip Chip.
