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

Any tape--any pitch. On our C5 platform every part number (in your database) has a package type assigned to it. The package type contains the information about the pitch and component orientation. When you load the feeder you scan the part number-

Thanks a lot,, so assuming we are using standard parts, with nothing out of the ordinary we could safely assume that a machine capable of 20 mil would be more than able to meet our needs down the road. | We are changing from through-hole to SMT, won

Thanks for the clarification! So in generic settings what are the normally the components with the smallest pitch? Will a machine with 20 mil capability handle almost anything? | | I was wondering what measurements are used to define pitch? | | |
