I have this NiPdAu small QFN packge sizes less than 2x2. I tried to do solderability Dip And Look test and there's always some units no wet on either ground pad and small I/O. Can someone help to explain why is this so difficult to set on this surfac

Hi there, does anyone experience in NiPdAu solderability dip & look test? I experiencing solder non wet issue on side I/O & also center ground for QFN package. Appreciate someone can offer me a solution. Thanks

All I can say is my regular "Get it analyzed", so you'll know what the streak is. Regards, Vladimir

Wise move :-) Please let me know the results of the analysis and we can take it from there. Vlad

am having wetting issues with two Burr Brown Op amps. Both are SOICs with NiPdAu lead frame finishes. I have attached a photo that shows a black streak the length of the lead (before soldering). This appearance is consistent of all leads and is exist

This is not something that we'd expect to see on NiPdAu finished leads. Help us understand the extent of the problem better. From your picture, it looks like a band of copper color with black on the outer portions of the copper color that bleeds int

What test is applicable to check for QFN package with NiPdAu leadframe if leads/pad are solderable? what are the options other than dip and look solderability testing? Thanks,

Thanks for the response guys! The parts are being sent to a local lab as we speak. I'll let you know the results when I get them. I am not sure the purpose of the copper band, but the black around the band is just shadowing from how I took the pi

Standard for appearance: J-STD-001 and IPC-A-610 committees eliminated the requirement that solder connections be "bright and shiny". Certain solderability protections; such as Au, NiPd, NiPdAu; can affect the surface texture of a solder connection,
