unless of course, it can be proved that the coating sticks to the uncleaned board and shows no defects as per IPC specs....but it doubt it

The key driver to aperture design is to assure a fillet of the proper height for the component temination and the reliability of the end-product customer use environment.

Hi, We found voids on BGA. Understand IPC stated as long as not more than 25% should be fine. So, is there any standard stated how many voids in BGA can be allow. Appreciate your help......

Part is most likely a QFN package. IPC-610-D has standards on solder quality for this new type of package.

Design to IPC standards unless a supplier provides documentation on why a change to the standard was necessary. Throw all supplier data sheets in the trash.

Brett, I've found out that it is not a defect with respect to Rev. D. You are correct about the thermal expansion but due to the size of the plastic SOIC's and SOT's they have eliminated it as a defect. Thanks, Tim

Steve just mentioned the 782 for ammo to customer, we usually get "it doesn't meet IPC" so we then say it was not designed to. let the pissin contest begin! Russ

Now THAT'S some good stuff right there. Earl just comes here to release his inner comedian because it's frowned upon by his upper crust IPC crones.
IPC is the trade association for the printed wiring board and electronics assembly industries.
