Precision of the shield

by:Fortuna     2021-02-03
Precision shield, composed of leg and cover body, leg and the cover body is active connection; The cover body is a square. Mainly used in mobile phones, GPS and other fields, is to prevent electromagnetic interference, EMI) And components on the PCB and LCM shielding effect. Categories: fixed, with SMT soldering directly to the PCB board; Detachable with structure and LCM, combination of or directly using the protrusions on the shielding_cover buckle in shielding_frame. Material: precision shield materials generally adopt stainless steel and the copper material, in which the copper is a kind of easy tin metal shielding material. This is mainly because the copper on the welding, heat and steam is better. Packing: packed in precision shield for SMT, conventional choice blister packaging. In blister, the design should pay attention to the following two questions: 1: place the shielding cover tray activity space is too big, can't learn, easy to swing when the patch must be placed in the tray material, there are 1. 0 mm activity space, cause material of swing is too big, too small to take material may not be able to take up. 2: the higher the precision stability of shielded enclosure, the higher the efficiency. Precision contact: I wish you all a happy New Year and all the best, if you want to learn more dynamic, can scan the qr code, pay attention to the public. , is committed to precision stamping processing factory of the world's most professional electronic components
