Hello,

I am using my own heat sink on the Munin2 construction.

>From my measurements, a 0.345" standoff is required for the circuit board.

Can anyone else confirm this?

When I lay the pcb on the copper bar, and drop in the mosfet, the top of the
drain is 0.1"
above the pcb, and drain tab is about 0.005" thick...hence 0.25" thick bar +
(0.1 - .005).095"

???

BTW, almost everyone's pcb's were shipped Monday, first class.
