Go with no greater than 0.005". Pleanty of paste and minimal shorting issues. 0.004" will even work

1. We do have PCB with 0402 component, Micro BGA ( 0.5mm pitch , 0.25 mm pad size ). PCB thickness is 0.8mm. What stencil thickness we should use. PCB size 40 mm X 60 mm 2. We have EKRA E4 , What will be optimum setting for above. Pressure, Scquge s

Durostone CAG762 is the optically sensitive version of ESD safe durostone. This link shows some good examples of durostone SMT pallets. If you do not have a machine shop, you will have to contract this one out I would say. http://www.permali.com
