I said: "Our electronic circuit board fabricators seal the boards in moisture barrier bags [MBB]. We discontinued the use of desiccant bags in these MBB because of concerns about the desiccant releasing materials that would affect the solderability

On "Flip Chip/uBGA Under-fill Visual Standards" � The third "Satisfactory" [The under-fill if by design should be visible � ], here the notation "if by design" is unclear. Does "according to product documentation" get to the point? The first "Acc

I visit customers on a contract base to get the machines in a status, that an operator can take over. These customers are usually small shops, who can not effort an engineer to set up the machines. I am not afraid of my job, if it does not require a

Sure, use of U-shape apertures is another way to reduce the amount of paste that you apply. That and similar schemes mentioned in the article are not a function of the flux used. We have used U-shaped apertures for MELF and mini-MELF. They are sug

| | | Does anyone have any information on stencil aperture/pad ratios for noclean solder paste. In the past I have experienced severe solder ball problems when using the same size apertures from aqueous products as I do with the No-clean products.
