China Circuit Board Shields The shielding case is mainly to prevent electromagnetic interference (EMI). It has a shielding effect for the components and LCM on the PCB board. Generally, the materials are nickel silver and tinplate. Gingerm can also provide other materials such as stainless steel to make covers, phosphorus bronze to make frames, etc. In order to better weld in tin, the phosphorus bronze shielding can needs to be treated with tin plating. Generally, the coil is pre-plated and then stamped. Gingerm can make new tooling and stamp products in volume according to the customer's drawing. Our average cycle is about 15-20 days to build new tooling, and we can make prototypes for customers for free to achieve mutual benefit and win-win. Most shielding cases are single-piece type, in order to facilitate maintenance the internal electronic components at anaphasis, double-pieces type can be used. The shielding case made by Gingerm can guarantee the flatness within 0.05mm, and it is produced using materials that are easy to weld in tin. Most of the shielding parts we produce is sold to the United States and Europe. Welcome to inquire about the price, we sincerely look forward to cooperation with you!
