摘要： In a method for manufacturing a shunt resistor, a resistor plate with a first side surface and a second side surface opposite to each other is provided. A first electrode plate and a second electrode plate are respectively pressed onto the first side surface and the second side surface, thereby forming a first connection surface between the first electrode plate and the resistor plate, and a second connection surface between the second electrode plate and the resistor plate. A first conductive module is placed on opposite ends of the first connection surface, and a second conductive module is placed on opposite ends of the second connection surface. Current is applied to the first and second connection surfaces via the first and second conductive modules respectively to weld the first electrode plate and the resistor plate, and to weld the second electrode plate and the resistor plate.

摘要： Current sensing resistors and a method of manufacturing the same are disclosed in the present invention. A composite material is firstly provided in the method. Then, a first portion of an alloy substrate of the composite material is removed along a first direction to form a plurality of first trenches. Next, a second portion of the alloy substrate of the composite material is removed along a second direction to form a plurality of second trenches, and a third portion of the alloy substrate of the composite material is further removed along the first direction to form the current sensing resistors. The current sensing resistors with small dimensions and an extremely low temperature coefficient of resistance can be produced rapidly by the method of the present invention.
