What is your micro BGA requiremnets? I mean ball dia / height with a 0.5 mm pitch? I can give you the stencil design, if you make known the parameters.

I'm looking for recommendations on pad and stencil design for products with 0.5 mm pitch BGA's. The latest info that I found in the archives of this forum dated more than a year ago. It didn't give me much confidence that assembly of such components

Balls are 0.30 mm diameter, with a height of 0.24 mm It's a 8*8 mm 184 pins BGA.

Go to http://www.ipc.org and look up IPC-7351 - Generic Requirements for Surface Mount Land Pattern and Design Standard The successor to the IPC-SM-782A is here! The document covers land pattern design for all types of passive and active components

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

I don't know your board, but for this specific part: 10mil round aperture on a 3.5mil stencil with type 4 paste wold be ideal

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

Hi Pete and Dave, I already check with Practical component, Tessera and TopLine Dummy component they said they only have up to 0.5mm pitch CSP. Anyway, thanks for your input... Do both of you know in the market right now is there any 0.4mm pitch C
