Stencil buy off procedure | 4 April, 2001

I'm writing the procedure for buying off the stencil. Can someone help to guide me on the most effective way of doing this job. Other than tension, mylar matching, dimensional checks, what are things that I need to consider. Pls help & thank you in advance.

ZAM_BRI- I don't know how effective this may be but some points to include in the buy-off procedure: Before submitting the PO for the stencil you may also want to do a CAD to Stencil comparison to verify correct apertures.There are SW packages and companies that do this regularly. You also need to define the apertures - laser cut, Trapezoidal, polished...... Also define frame - frameless, Solid, hollow. Define the fiducial information-etched on, dot, or hole.

You can also refer to IPC 7525 Stencil Design guidelines for additional help.
