Laser Stencil 598 x 598 mm Built on 0.12mm Stainless Steel Foil for SMT usage.
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
The data file is used directly to produce and reduce the error rate;
The opening position accuracy of SMT template is very high: the whole process error is ≤ ±4 μ m;
The opening of SMT template has geometric figure, which is advantageous to the printing and forming of tin paste;
ISO9000 certified manufacturing factory;
12 hours quotation;
Quick Lead time: 1-2 days;
No MOQ, low cost for prototypes and small runs quantity;
1.3 Application
SMD package such as PLCC,QFP,0402,0201,BGA,Flip Chip.
