Stencil type and design for 0.65mm pitch QFP100 | 10 May, 2000

0.65mm pitch QFP. I believe that this is the borderline for Fine Pitch. Will I have a good paste release with Chem-etch matched with a rubber squeegee? I'm planning of a 15% reduction on the Width and no reduction on the length. Any feedback whether a laser cut or Chem-etch is advisable since we will be using a rubber squeegee for paste printing and it's not a high volume product (roughly about 500 bds per month.

thanks
