SMT Stencil Laser Cut 0.1mm Stainless Steel Shim for BGA Package
1.1 General description
This is a type of SMT stencil (100% laser cut) built on 0.10mm stainless steel foil with aluminum frame 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 half-etch dented 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;
Strict WIP inspection and monitoring as well as working instruction;
Delivery on time. Higher than 99% on-time-delivery rate;
Customer complaint rate: <1%
Quick CADCAM checking and free quotation;
More than 15 years of experience;
1.3 Applications
SMD package such as PLCC,QFP,0402,0201,BGA,Flip Chip.
