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

We have a problem with QFN IC's with NiPdAu plated pads. Our ULC's don't see the pads due to the almost ideal reflection. Vision sees the pads almost black. As we don't have OAL-cameras (which can help in this case, I assume), I am thinking of back-l

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

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,

40% in wetting problem. I would like to know any specific reflow profile in order to acheive good wetting at this type of lead. Besides, any specific paste e.g. halide containing paste required

We use SnPb paste and bar with leaded and non-leaded component finishes. The predominant finish on components we use is Tin, there are a few NiPdAu. We've had no problems with the component finishes used in the SnPb process.

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

Dave, thanks. I was going to change Cu/PD/Au to Ni/Pd/Au and then my question is: Has anyone had soldering issue with components (ICs) with the above finish during reflow and/or had to change the oven profile to improve the wetting. Sorry for confusi
