The fundamental difference between FPGA vs CPU lies in the difference between software and hardware; CPU is a Von Neumann structure, which executes a series of instructions serially; while FPGA can realize parallel operation, like embedding multiple CPUs in a chip, whose performance will be ten or a hundred times that of a single CPU.
PCB Via fill is a material used to fill through holes in a PCB board. Through holes are holes punched in a PCB to connect different circuit layers so that current or signals can flow through. The purpose of through-hole fillers is to prevent liquid solder pads or other impurities from remaining in the through-holes,
Bendable Circuit Board, or Flex PCB, is a type of circuit board that is manufactured using a flexible substrate. Its best feature is that it can be flexibly bent without affecting its performance or conductivity. Compared to traditional rigid circuit boards, flexible circuit boards have better adaptability and applicability. FPC is the United States in
