Introduction:
Laser Stencil Heavy Copper PCB means a laser cut SMT stencil built on 0.12mm stainless steel foil with 598 mm x 598mm 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.
Advantage:
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 is4
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.
