Hi, We are using a 15mils to 5 mils step stencil with a metal blade. The 15mils area the surface is smooth and polish and in the 5mils area the surface is rough and porous because of the laser process. In the 5 mils area where there is no aperture t

Please check what is the actual pitch size. I found some of the designer use 15.7 mil pitch and no accumulate ie 15.7, 15.7 and 15.8...... Also, I recommended the pad width should be 10 - 11 mil for 0.4mm pitch. You can open the 10 - 10.5 mil aper

| Does any body know stencil manufacturer in states or south east asia for electroforming processes and step down from 5mil to 3mil. | | Thanks! | Daniel, I do alot of work with Photoetch stencils in Massaschusetts. I do not have the Phone number h

Dave, Thanks for the info! Yes, I have read the IBM document and realized that I was missinformed about the paste volume. I need 5000 to 5600 cubic mils of paste. Running the numbers I get a 32 mil aperture with a 7 mil step (the rest of the board

I would suggest scoring if the profile allows, leaving residual material of circa 40 - 50 mil - That is what I do on a 125mil thick PCB width of the pis is approx 200 mil Mouse bites on a board as thick as 135 mil will mean its extremly difficult to

On 0402s we use 20x25 mil pads with a 15 mil gap between the pads on the pcb with ENIG finish, 5 mil stencil with a 1:1 aperture (20x25 mil) and SAC305 lead free solder paste. We very rarely see any tombstoning on 0402s using this setup.

Dear all There are alot sockets in our products,BIB.These skts are lifted abit after being solderd with wave machine.If the skts become lifted, how much tolerance of the high is acceptable? as example 1mil~5mil,or,1mil~8mil. Pls advise me. Thanks in

We are manufacturing a PCB that uses an integrated circuit that has a leg spacing of 10 mils, other components on the PCB are 1206's and 0805's. Is it possible to make the stencil apertures 10 mils apart or is there another way of making the stencil.
