The mobile phone motherboard shield manufacturer tells you what to pay attention to for the wireless module shield? At present, there are many types of shielding covers for mobile phone motherboards, and wireless modules have been used in various fields of the Internet of Things. It is the most important link in the modern Internet of Things and is very popular in the market. There are many types of integrated shielding layers used in wireless modules, simple structure and high cost performance. . But have you noticed that most wireless modules come with a metal casing? Do you know what effect this metal shell can play on the wireless module? The metal shell on the wireless module is called the wireless module shield, which is one of the hardware facilities of the wireless module. Its main functions are divided into two: 1. Prevent interference and radiation to the outside world when the wireless module is working; the higher the power of the wireless module The interference and radiation generated will be correspondingly larger, so adding a metal shell can reduce these interference and radiation to a certain extent. 2. Shield the interference from the outside world to the wireless module; in the working environment of the wireless module, there are many complex interference sources, such as the external electric field and magnetic field, which are invisible and intangible. After adding a shielding cover to the wireless module, these external interference sources can be well isolated. Generally speaking, the shielding cover is very important for the wireless module. One is that it can improve the anti-interference ability of the wireless module. The second is that the stronger the anti-interference ability, the correspondingly the transmission distance of the module will be increased. Therefore, the wireless module adds a shield. The cover shell is still very necessary. To increase the wireless control distance, simply pursuing high sensitivity or increasing the transmitting power of the transmitter cannot completely increase the control distance, because in practical applications there will be factors such as power supply, electromagnetic interference in the working environment, or power ripple interference, so it must be integrated Consider the various anti-interference capabilities of the RF receiving end.
