Hi Jim,

It is a pain for an AOI reject/fail because the AOI template does not
match the component marking. I did not have this kind of component with
solder covering the terminations. 

I will reject the remaining parts in the reel or reels with the same
batch or lot code. I would consider to address this issue with the
vendor/manufacturer and ask them to submit an 8D report. They may have
done a sloppy process.

The solder is directly on top of the silkscreen marking.  The solder
covering the resistor terminations is part of the chip manufacturing
process.  A little sloppy and something that I have not come across
before.  

Other thoughts?

Is the solder on top of the white silkscreen markings.   Kinda of
strange.   Is the extract solder there to cover the Ag termination and
keep for creating whiskers.

Victor,

Hi All,

Please see links below. The extra solder that is attached to the
termination side but also covering the part marking.

Obviously, our AOI is failing for the part marking which is a pain. I'm
curious on what everyone's thoughts are regarding the extra piece of
solder extending out on the body of the resistor? I've tried to remove
the extra solder but it is attached and doesn't come free. Besides
having to deal with the AOI failures, what do you think about the extra
solder and should I replace the resistors?
