I am assuming you are referring to the two holes at the upper right next to the regulator - probably filled with solder from the wave-solder operation.geoffct wrote:I made a heatsink. I measured the pad as best I could, but if you could post the dimensions of the pad and holes that might help people in the future.
The two holes are 0.178" from the top edge of the board (ampseal to the left for board positioning reference) - this is the Y coordinate. The X coordinate, measured from the right-hand side of the board, is 0.6 " for left-most hole and 0.2" for the right-most hole - the holes are 0.4" apart from each other.
The VB921 heatsink can be moved a bit by loosening the single mounting screw. Also, the board slides around a bit on the case rails. It is possible to get the heatsink to rest against the side of the case.geoffct wrote: Also I noticed the VB921s heatsink is out from the case, so I will be replacing that heatsink with 1/4" thick material.
