造。 In printed wiring on printed wiring boards, the conductor resistance is increased by partially narrowing the conductor width.
The feature is that when a large current flows compared to the current in normal operating conditions, the portion where the conductor width is narrowed is fused, thereby preventing damage to components mounted on the circuit after this portion. Structure of printed wiring board.
