Yes, I come from a land down under...currently participating in an unnecessary war in IRAQ! But what about paste replenishment on both heads? Wastage? Damage to stencil problems if any? Maintenance? etc... thanks for all your info but I think I nee

Stencil Design for Resistor Net Array 0402

Electronics Forum | Thu Mar 27 11:49:18 EST 2003 | kenlchin

In printing,the thickness of solder paste perpendicular to the Squegge direction is always lower 1 mil than that parallel to the Squegge direction,so Insufficient Solder may occur.I think you may slow printing speed or widen appertures to resolve it.

I'm a user changing over from WS-609 to WS-709. WS-709 has less voiding problem and longer stencil life than WS-609. Ws-709 has a less foaming during washing process. Thanks, Myu

0402 Adhesive printing is possible with thicker stencils in order to allow mixed component technology. We have successfully printed 0402's with a 0.008" thick SS foil. Total material release is not achievable at this thickness, but not required u

Yukim, I had experienced this problem with 0402 package. I resolved it 100% by reducing stencil thickness from 6 mils to 5 mils and changing the apetures from 1:1 to homebase.

Mini Micro Stencil sells a mirror for $40.00. This thing is great and is made from metal so it won't break so easy. It is also only .008" thick. minimicrostencil.com
