Yea, I know. You almost need a milling machine. Like what they use for doing engine heads. If you know the layer depths, you could program the machine and setup a routing bit and vacuum nozzle head and let it rip.Had some time to grind away at one of my spare boards:
Going all the way down to the inner layers is going to be an absolute pain in the back.
I'll need to stock up on wheels for my grinder first.
Also it looks like the additional signaling two layers are right in the middle of the boards hidden under yet another set of VCC/GND plane layers.
Yea, I know, right?Gorgeous. You have no idea how relieved I am to see the metal clips on the RAM sockets!
