摘要

A reliable microchip controller board and a manufacturing method thereof suitable for mass production are provided. A board wherein a programmable microchip controller is mounted includes; terminals for writing a program into the microchip controller and a circuit pattern connecting an operating terminal to shared terminals which are disconnected. A non-programmed microchip controller is mounted on the board in a state where patterns are disconnected and then programmed. The disconnected portion is connected thereafter.
