> Subject: Burrs on FETs
>
> We have identified a problem where burrs on FET tabs cut through the
> insulator (dry grease on Kapton), and short to the heatsink. To avoid this
> possibility, we now include a quick sanding operation at part prep. Very
> labor intensive, inconsistent, wasted time..... Anyone have similar
> problems? What do you do? Any automated equipment to do this operation?
> Thanks in advance. Joe
