The resistance production process of mainstream resistors is an important electronic component production process, which plays a crucial role in electronic devices. Resistors are passive components used to limit current, typically made of conductive materials with a specific resistance value. In electronic devices, resistors are widely used in circuits for functions such as current regulation, voltage division, and current limiting.

The resistance production process mainly includes material preparation, forming, sintering, coating, testing, and other steps. The following will provide a detailed introduction to the resistance production process of mainstream resistors.

Firstly, material preparation is required. The main material of resistors is conductive material, usually metal or carbide. During the production process, the necessary conductive material needs to be prepared and mixed in certain proportions. The mixed conductive material needs to undergo processes such as crushing and sieving to ensure material uniformity and purity.

Next is forming. Forming is a key step in resistor production, determining the shape and size of the resistor. Typically, a pressing forming method is used, where the mixed conductive material is placed into a mold and subjected to a certain pressure and temperature to form it. The formed resistor needs to undergo sintering to increase its density and hardness.

Then comes sintering. Sintering is an important step in resistor production, where high-temperature treatment is used to bond the particles in the conductive material into a uniform whole. Temperature and time need to be controlled during sintering to ensure the quality and performance of the resistor. The sintered resistor needs to undergo cooling to reduce the temperature and reach a stable state.

Subsequently, coating is applied. Coating is a key step in resistor production, determining the resistance value and accuracy of the resistor. Typically, a coating method is used to apply the conductive material to the surface of the resistor, forming a thin film. The thickness and uniformity of the coating have a significant impact on the performance of the resistor and need to be precisely controlled.

Finally, testing is conducted. Testing is the final step in resistor production, where the resistance value, accuracy, and stability of the resistor are checked. Typically, resistance measuring instruments are used for testing to comprehensively check the resistor, ensuring it meets the specified standards and requirements. Resistors that pass the test can be packaged and sold.

In conclusion, the resistance production process of mainstream resistors includes material preparation, forming, sintering, coating, testing, and other steps, each with specific process requirements and control methods. Through strict production processes and quality control, high-quality resistors with stable performance can be produced to meet the needs of various fields. As an indispensable component in electronic devices, resistors will continue to play a crucial role in driving the development and advancement of electronic technology.
