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

Maybe something like this could work?

I am optimizing a stencil opening for BGA with 0.4mm pitch and pad diameter of 0.2mm. Can anyone advice of stencil thickness and stencil opening I can use in order to have a good paste release. Thanks for all your answers.

I've searched the archives and maybe my search skills aren't up to snuff but I couldn't find much. I'm curious what people are doing for 0.4 mm pitch BGAs, assuming a type 4 paste. Pad diameter? SMD or NSMD? Stencil thickness? Aperture diameter? Us

Khalid, Just from experiance the actual would be 0.4mm but the inspection size would be 0.3mm. This should not matter since you should be able to pull up the spec sheets on any part you place.( All you need is the Vendor and the manufacting part numb

yo Evt, ".., what's the difference?". Answer: Huuuge!! between running 0.4mm pitch QFP and a BGA of same I/O, in terms of handling, storage, feeding (trays), p&p, inspection, test, rework, etc.......

What is the difference between jet printing & jet dispensing. Our's is small prototyping, high reliability PCB assembly business. The SMT components used are up to 0.4 mm pitch BGA & 0201 size chips. Which is more suitable for us?

6 mil (0.15mm) for the 1.13mm pitch BGA, and 4 mil (0.1mm) for the smal QFN with 0.4mm pitch.

Hi Jandon, Thanks, I will try it on my DOE.

Yes, 0.25x0.25 square could work @0.1 thickness, use nano-coating or electroform stencil for better solder paste release.
