One of the DFM suggestions I've seen is to remove the solder mask web, i.e. the mask between pads on 20-mil QFP devices. The rational is that if the mask is thicker than the pad the mask can prevent the stencil from making intimate contact with the

We're getting field failures in a high impedance portion of the circuit. Think the unpopulated pc card has contaminates because we were able to grow dendrites by applying a 9 volt battery across the suspected pad, placed a drop of de-ionized water o

| Has anyone ever heard of testing solder paste quality by pasting a board and making a determination of the quality by measuring paste height and width after the board is pasted. Would you consider this a valid test for solder paste testing? | I ha

| Does anyone have any experiences with EMC stencil screen cleaners or can you recommend a good one? | SMarTsonic makes an excellent cleaner. As Bill states, it uses ultrasonics and an EPA approved detergent to wash stencils and boards. However,
