Manufacturing method of PCB (Printed Circuit Board) integrated with IO (Input/Output) terminal

The invention provides a manufacturing method of a PCB integrated with IO terminals. The manufacturing method comprises the steps that (1) the PCB is designed according to an electrical schematic diagram and an engineering BOM; (2) providing a flexible substrate for manufacturing a PCB (Printed Circuit Board); (3) IO terminals required by the electrical schematic diagram are integrated on the PCB; (4) one end of the IO terminal is integrated on the PCB for signal conversion, and the other end of the IO terminal is a multi-pin plug connector which is connected with a plurality of wires to form a wire harness; and (5) carrying out power-on test until the circuit of the PCB is qualified. According to the invention, bulk materials are concentrated on one PCB circuit board and are externally connected with a lead to form a wire harness, and a plurality of material numbers are combined into a material number of one PCB circuit board. And the PCB is simple in process, quick to assemble, low in failure rate and conve
