What do others use as far as solder paste type, stencil thickness and aperature size for a .4mm Ball Pitch CSP. Ball diameter is .3mm. Please let me know your thoughts or what you use. Thanks

It is recommended that the thickness of the stencil of 0.1mm, the steel mesh should be partially nano-coated. It is best not to dry easily, and the particles are not easy to be too large. I have tried ALLPCB for this kind of BGA in the past and they

A bit more information will help people give a more educated response. What size res/caps? Any fine pitch ICs? BGAs? Lead or lead free? What quantity of components and/or boards are you loading? Will it be high mix, low volume or lower mix, hig

What's important in stencil printing (which differs from screen printing) is providing a consistant volume of paste at each interconnect. The process window varies in proportion to the pitch. More than 60% of all defects are related to solder depos

Also in some instances a 10% decrease on glue size would be needed for the smaller S.O.T. sizes out there. If you are dealing with a good company to make your screen they should send you back a preliminary art work file on the Screen to be made so yo
