Rigid substrates offer high thermal stability and low expansion and are easier for the pcb assembly process. https://www.123articleonline.com/articles/1285427/rf-microwave-pc-board-applications There are numerous uncertainty in RF (radio frequency) PCB (printed circuit board) designs. Whenever it comes to circuits with frequencies below microwave (particularly low intermediate frequencies digital logic circuits), however, careful design https://www.123articleonline.com/articles/1262150/what-is-a-keyboard-pc-board As all other things are the same, a plate-assembled keyboard is more robust than a PCB assembled keyboard and has a stronger feeling. The overall quality of the keyboard and its case play, too, although it differs from a plate of aluminum or steel between the typing of a laminate sheet (PCB).
