PURPOSE:To reduce the quantity of trimming while improving quality by reheating a resistor in order to adjust a resistance value after a resistor baking process. CONSTITUTION:A protective film is formed through a resistor reheating process 14 and the resistance value of a resistor is measured, and a heating temperature and the time corresponding to the quantity of deviation with a design value of the resistance value are set and the resistor is reheated, thus adjusting the resistance value, then resulting in normal distribution in which the desired value of the center is closer to the design value. Accordingly, not only minus defective resistors are reduced but also the quantity of trimming working can also be minimized. |
