ABSTRACT:
A hearing aid using a printed circuit board (PCB) is provided, which minimizes internal wires since components of the hearing aid are disposed on the PCB. In the hearing aid using a PCB, hearing aid components can be automatically disposed and soldered on the PCB, and through this the total process time, including manufacturing time, can be substantially reduced.
