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

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

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 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.

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

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

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
