Product Description

This Shielding cover produced by our lijingda factory is a kind of a cover-shaped part made of thin metal sheets (such as white copper, stainless steel) through precision stamping or etching processes, usually with fixed feet or welding points. Its core value lies in its ability to precisely cover specific components or areas on the PCB board, forming a local Faraday cage, thereby effectively isolating the electromagnetic interaction between this area and the outside world. Its design is very flexible. It can be square, round, or irregular according to the shape of the components, completely depending on your shielding requirements. Its core task is to act as a "localized electromagnetic barrier", which is directly related to the stability of your specific circuit function and the electromagnetic compatibility (EMC) of the entire system.

Application

Our Shielding cover is a must-have component for all high-density, multi-functional PCB boards. It is widely used in the mainboard of smart phones (shielding the RF and power parts), the wireless network card module of notebook computers, the control unit (ECU) of automotive electronics, the signal processing board of communication base stations, and the main control board of various Internet of Things devices.

Feature

The first impression of our Shielding cover is precision and neat. Its shape has a clear outline and smooth edges without burrs. If it is a welding type, its welding feet or pads are flat and suitable for automated welding. If it is a card deduction, the design of the card feet is reasonable and the elasticity is moderate. This high precision, which is demonstrated from size to detail, is the quality guarantee for it as a precision electronic component.

Company Advantages

Because our company is a professional manufacturer with a profound understanding of PCB layout and precision metal stamping technology. We have a very good understanding of how the size, shape and fixing method of a shielding cover affect its final performance and producibility. We possess a complete set of core technologies and production capabilities, ranging from mold design, precision continuous die stamping, automated surface treatment to clean packaging.
