Product profile

 

 

1.1 General description


This is a type of laser cut SMT stencil built on 0.12mm stainless steel foil with 598 mm

x 598 mm length and width. It’s fabricated per IPC 7525A using supplied Gerber data,

squeegee area locating in the center. 4 sides of edges 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. ISO9000 certified manufacturing factory;
E. 12 hours quotation;
F.  Quick Lead time: 1-2 days;
G. No MOQ, low cost for prototypes and small runs quantity;
