Aluminum Framed SMT Stencil

(Stencils are custom-made products, the pictures below are just for your reference)

 

1.1 General Description

SMT stencil in our house, framed or frameless are 100% laser cut. The thickness of stainless steel foil ranges from 0.05mm to 0.4mm, with size 300mm x 300mm to 600mm x 600mm. They 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.

 

1.3 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
