Should PCB mounting holes be grounded?
Mounting holes should generally be plated as this allows mounting with metal screws. Because floating bits of metal can be sources of EMI, the mounting holes should be connected to some ground net (earth (PE), signal ground (SGND), a grounded enclosure, etc.).
What is a hole in PCB?
Through holes on a PCB refer to a hole that is drilled from the top and through to the bottom of a PCB, these can be plated (PTH) or non-plated (NPTH).Through holes became plated-through holes (PTH) in order for the components to make contact with the required conductive layers.
What size screw do keyboards use?
Most keyboard mounting screws are standard and about 3/16″ diameter.
What screwdriver do I need to open a keyboard?

How do you mount a PCB board?
Hold the circuit board directly over the location you wish to mount it, and mark the location of the screw holes on the enclosure. Mount the printed circuit board to the stand-off spacers. Place a 3/8-inch nylon washer over the top of the drilled hole, and insert a 1/2-inch screw through the hole.
What PCB means?
printed circuit board
A printed circuit board, or PC board, or PCB, is a non-conductive material with conductive lines printed or etched. Electronic components are mounted on the board and the traces connect the components together to form a working circuit or assembly.
