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 420 mm x 520 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
A. The data file is used directly to produce and reduce the error rate;
B. The opening position accuracy of SMT template is very high: the whole process error is ≤ ±4 μ m;
C. The opening of SMT template has geometric figure, which is advantageous to the printing and forming of tin paste;
D. Engineering design prevents problems from occurring in pre production;
E. Team with passion, discipline, responsibility and honesty;
F. Door to door shipment service;
G. More than 15 years of experience;
H. Hassle-free, one-to-one after-sales service;

1.3 Application

SMD package such as PLCC,QFP,0402,0201,BGA,Flip Chip.
