Who controls the process control block(PCB)?

Recently, I have learnt about kernel and find a question that who controls the process control block(PCB)?The kernel or the process itself? Does it differ in different platform (windows/Linux)? So far, I know PCB is controlled in hardware, but I can't get to the right answer.

OS tracks all necessary information about each process running in the system in PCB. Process Control Block is a data structure representing a process in the OS.

Process control Block PCB is specially defined in the core of the OS for each process.

What Others Are Asking

How can I handle missing solder mask opening on PCB footprint?

I have three through-hole PCBs that are missing front and back solder mask openings for two of the components. The solder mask (usually green) is covering the front and back solder pads. All other pads for all other parts are exposed. Is there a good way to remove the solder mask so that I can solder the components to the board?

Can I use 1 and 2 ounce copper with small pitch devices?

In common, I use 2 ounce copper as rule for all my PCBs. On a recent board, I am using a 0.5mm pitch, relatively large micro, and noticed the pads aren’t very flat. Assembly went fine with the protos, but I’m wondering if 1 once copper would provide for a flatter landing service. Any advice on assembly reliability related to copper thickness for such devices?
