Hi,

Have anyone encountered that PCB from different suppliers give different
paste height.

We are using 3 PCB suppliers for one of our product, and the average paste
height we are getting (on 2 suppliers), using 6 mil stencil with rubber
squeegee (70 durometer) gives an average paste height of 6.5 mil. However,
there is one supplier's PCB that gives the average paste of 8 mil.

We need to double the squeegee pressure to achieve the paste height of near
7.0 mil

Could anyone advise me the cause to such issue.

Thanks

Poh
