While we're on the 20 mil subject ;
the same apply on the polyimide ? ; as they have better release ratio than

<< Hi Technetters,

 What kind of stencil thickness you would recommend for 20 mil pitch QFP?

 4, 5 or 6 mil ?

 Thanks in advance.

 Hi Poh!

I always get a 6-mil with the industry standard aperture reduction (20%
smaller)... always  works for me without a problem.
