Advantages | 2) Easy to solder with tin | 1) Cheaper than copper nickel 2) Bright surface, not easy to oxidize and rust 3) High strength 4) Good shielding performance | 1) Bright surface, not easy to oxidize and rust 2) Excellent shielding performance 3) Easy to solder with tin 4) Good oxidation resistance and corrosion resistance | |||||
Disadvantages | 1) Easy to oxidize and rust 2) The shielding effect is not as good as stainless steel and copper nickel type. | Hard to solder with tin, it is only suitable for shielding cover, not suitable for shielding bracket. | 1) Material is softer 2) High cost |
The main function of the shielding case is to block electromagnetic waves in the cover, protect the user from the harm of electromagnetic radiation and avoid interference with other electrical appliances around, to a certain extent, ensure that the components are protected from dust and extend the service life. Shielding cases are widely used in notebook computers, PDAs, PHS, CDMA, car navigation systems, ITS, optical drives, mobile phones, shielding boxes, test equipment, military equipment etc. According to customers' requirements, we can use carrier tape packaging for shipment, which is convenient for customers to use automatic surface mounting machine for mounting and fast mounting on PCB boards. The shielding effectiveness is good and the inside of the cover can be electrically insulated. The general shielding effect is 40 ~ 55dB / 100MHz ~ 1GHz. |
