1. The itinerary arrangement of the spring thimble during work must be based on the indoor space of the product to be used when selecting the spring thimble, and choose the one within the scope of the work schedule; if the indoor space is too small, the elasticity of the spring thimble will be reduced too much. During the hazard use period, if the indoor space is too large, it will cause untimely contact, unstable characteristic impedance, and instantaneous interruption.
2. Electroplating material Electroplating material in the spring thimble has the effects of improving conductivity, avoiding air oxidation, and abrasion resistance. Different raw materials have different effects. Like gold, it has excellent conductivity and is aimed at high current radio frequency. For connectors, products with high characteristic impedance requirements are generally selected for electroplating gold.
3. What is the hazard of the electroplating process layer. The spring thimble is easy to touch during work and it will cause a certain amount of friction. After a long time, it will be damaged. The thickness of the electroplating film also has a great hazard to the life of the product. If the electroplating process layer is damaged to a certain extent, the resistor will be too large and the characteristic impedance will be unstable. The electroplating process layer of the 100,000-times spring thimble is undoubtedly thicker than the 10,000-times. Therefore, in the case of product model selection, please try to choose the electroplating process regulations according to the requirements.
4. The harm of resilience
The contact force of the spring thimble comes from the internal spring. The magnitude of the spring spring force can immediately harm the characteristic impedance size of the spring thimble and how reliable is it. If the elasticity is too large, it will increase the friction resistance and affect the service life of the spring thimble.
