Product Details

Product profile

 

 

1.1 General description


This is a type of laser cut SMT stencil built on 0.12mm stainless steel foil with

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


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 and on-time delivery;
E. Great customer service;
F.  Diversified shipping method;
G. No MOQ, low cost for prototypes and small runs quantity;
