<p>PURPOSE: A method of connecting resistors in an automatic gain adjuster is provided to enable a smooth gain adjustment even in a high electric field by inserting a jumper instead of a resistor onto a component mounting surface, mounting a chip resistor on a circuit pattern surface, and then fixedly connecting the jumper and the resistor to each other by a soldering process, thereby preventing resistors from coming into contact with a chassis. CONSTITUTION: A circuit pattern surface and a component mounting surface are respectively formed on upper and lower surfaces of a board so as to produce a PCB(S10). A jumper is inserted onto the component mounting surface of the PCB(S20). Wires of the jumper protruding from the component mounting surface toward the circuit pattern surface are temporarily fixed to a chip resistor mounted on the circuit pattern surface(S30). The chip resistor is fixedly connected to the wires of the jumper by a soldering process in the circuit pattern surface(S40).</p> |
