Looking to see what grade this would fall under for pricing what do you guys think. it weighs about 2lb

UPDATE: After i removed the Aluminum from the board what would you guys grade this board as now?

Like that: midgrade.
All the weight is in the heatsinks.
Carefully remove the heatsink ls for anything from peripheral to gold cap chip board.

After removal of the Aluminum this is what is left what grade do you this would fall under. Trying to see if it is worth removing the Aluminum

Wow on multiple things.
I didn’t expect you to actually remove the heatsinks. ;)
I also very much didn’t expect that underneath them!
I was figuring maybe peripheral or even low T...!

While only just barely, in the case of what’s posted IC pop looks to clear high telco. Nice massive collection of gold flashed ball down holes. (Down, drip, drop, dip choose your D).
That’s a lot better then I expected!

Thanks for sharing.

Explain why no bga or plcc chips underneath the AL sinks? Is it just open n prepared like a bread board? Ready to stick n go kinda thing?

What would this board be used for?


I've noticed too, all small scales have AL blocks underneath the scale that have flashings or foils just like this board; on the block.

There’s two sides. One side has ICs.
The massive aluminium fin collection makes active cooling an afterthought in an enclosed rack. Two 40mm fans properly fitted could keep this in operating temperature limits.
