Subject: [TN] Stencil (Open) Aperture for No Clean and W.S.


Ladies and Gentlemen:

Do you have any standard, or rule about the Stencil
Aperture for No Clean and W.S for SMT product?

Is there any site that contain those information?

We have had problem with solder balls (No-Clean),
in-sufficient solder (for both No Clean and W.S), and
Bridging which we have found out that the root was the
imperfect design of the stencil aperture.

Your help is greatly appreciated!

Stacy
