Mainstream Production Process of Wound Resistors

Wound resistors are common electronic components used for current limiting, voltage regulation, and voltage division in circuits. They are made by winding a metal resistance wire wrapped in insulating material, providing stable resistance values and good high-temperature resistance. In the manufacturing of electronic devices, the production process of wound resistors is crucial as it directly affects the quality and performance of the products. Below, we will detail the mainstream production process of wound resistors.

1. Material Preparation The main materials for wound resistors include resistance wire, insulating material, and terminals. The resistance wire is typically made of nickel-chromium alloy or copper-nickel alloy, with high resistance and stability. Insulating materials such as glass fiber cloth or ceramics are chosen for their good insulation and high-temperature resistance. Terminals made of copper or aluminum are used for circuit connections.

2. Winding First, the resistance wire is wound into a spiral coil according to design requirements, and then the coil is fixed on the insulating material. It is important to ensure uniform coil density and complete insulation material wrapping during winding to ensure the stability and durability of the resistor.

3. Welding The wound coil is welded to the terminals to form circuit connections. Welding temperature and time must be controlled to avoid overheating or insufficient heating, which could result in weak welding or damage to the resistor.

4. Encapsulation The welded resistor is placed in a packaging mold, and insulating material is injected or insulating varnish is applied to form a protective shell for the circuit. The encapsulation process must ensure the sealing and corrosion resistance of the shell to ensure the stability of the resistor in harsh environments.

5. Testing The produced resistors undergo performance tests such as resistance value, voltage resistance, and temperature resistance to ensure they meet design requirements. The testing process must be precise and reliable to guarantee product quality and performance.

The production process of wound resistors requires strict control at every step to ensure product quality and performance. As electronic devices continue to evolve, the production process of wound resistors is constantly innovating and improving to meet market demands and technological advancements. It is hoped that the above introduction will provide insight into the mainstream production process of wound resistors and serve as a reference and guide for the manufacturing of electronic devices.
