[Amps] New NXP BLF578XR 1200W LDMOS FET is "indestructible"

[Baruch Zilbershatz]

Hello there

The method you describe is the good one with the small tub for these
devices.

I do not have a mechanical  tool shop like you guys my means are limited I
polish the copper slaband use an common tools to verify flatness.

Indeed toothpaste is one means among other s.

In one commercial place that I visited I saw also steel wool being used too
And other water based polishing means( polish stuff)
