Beijing chip shield, take you to understand the knowledge of shield + daily production capacity of 3000000 strokes

Hello everyone, I am a precision shield manufacturer hardware responsible for the production of Beijing chip shields. Today I will bring you some knowledge about shields. Let’s take a look! The chip shield material can be ZSNH zinc-tin-nickel alloy, or nickel silver (good performance and easy processing), or stainless steel (only shield cover). The shielding frame is made of ZSNH zinc-tin-nickel alloy or nickel silver to ensure good welding performance. The thickness of the material is generally between 0.1-0.2mm, and 0.2mm is more commonly used. Chip shields are also called magnetic shields. They are generally made of magnetically permeable materials. The best is permalloy, but they are expensive. They are usually made of magnetically conductive silicon steel strips or iron. Then in toroidal transformers What is the main function of the chip shield? The toroidal transformer using the shielding cover has small magnetic leakage and low interference. For power amplifier transformers, electromagnetic interference can be largely eliminated. The sound quality is quite pure and noise-free. It is mainly used for magnetic shielding, effectively reducing the interference of magnetic field on circuits and electronic components. Choose, choose success
