(Stencils are custom-made products, the pictures below are just for your reference)
1.1 General Description:
SMT stencil are fabricated per IPC 7525A using supplied Gerber data, squeegee area locating in the center.Fiducial marks are half carved on the back side 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 Benefits:
1.) The data file is used directly to produce and reduce the error rate;
2.) The opening accuracy of SMT template is very high: the whole process error is ≤ ±4 μ m;
3.) The opening of SMT template has geometric figure, which is advantageous to the printing and forming of tin paste;
4.) Quick and on-time delivery;
5.) Diversified shipping method;
6.) No MOQ, low cost for prototypes and small runs quantity
1.3 Applications:
SMD package such as PLCC,QFP,0402,0201,BGA,Flip Chip.
1.4 Manufacturing Essentials:
1) Aluminium Frame
2) Laser cut
3) PCB locate in the middle of squeegee area.
4) Stainless Steel Shim: In general a standard thickness of 5 mils. For microBGA step down in the area to 4mils. For fine pitch QFP reduce the paste apertures by 10%-15% at centre.
5) Reduction for fine pitch components
6) Engraving is required
7) Electro Polishing
1.5 Available Thickness of Stainless Steel Foils:
0.05mm, 0.06mm, 0.08mm, 0.1mm, 0.12mm, 0.15mm, 0.18mm, 0.2mm, 0.25mm, 0.3mm, 0.4mm
1.6 Commonly used Frame Size:
Although stencil is custom-made product, there are also some sizes which are in common use. For example, 300mm x 300mm, 520mm x 420mm, 600mm x 600mm
