This is a type of SMT stencil (100% laser cut) built on 0.12mm 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. Quick turnaround prototype;
E. Door to door shipment service;
F.  Delivery on time: >98%
G. Customer complaint rate: <1%
H.  Hassle-free, one-to-one after-sales service;
I.    More than 15 years of experience;

 

 

1.3 Application


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