Electronic tube shielding cover, what are the contents of the shielding cover + 15 years of stamping experience manufacturers

Hello everyone, I am a hardware shield manufacturer responsible for the production of electronic tube shields. Today, Xiaoshuo of Hardware brings you some knowledge about shielding covers. Let’s take a look! Mobile phone shielding cover design. The shielding cover is an alloy metal cover, which is a vital component to reduce the display radiation. When used in MID or VR products, it can effectively reduce the mutual interference between modules. As shown in the figure, it is common in The isolation between the main control function module and the power module and the Wifi module. Xiaoshuo takes everyone to see? What issues should be paid attention to in the design of motherboard shielding cover: Generally, there are products that use wireless communication, and shielding frames are usually designed on the circuit board (to isolate electromagnetic interference (EMI), but the shielding frame should be used. To function, two parts are generally needed, one is a shield frame that uses SMT to make parts, and the other is a shield cover. In this case, more than two sets of press molds must be opened. The surface of the shield frame is mostly hollow. It is directly welded to the main board. The shielding cover is buckled around the sides and directly buckled on the shielding frame. This makes it easy to remove the shielding frame without removing the shielding frame when disassembling and repairing. In MID or VR products In PCB design, we often shield some modules. 1. Power module (PMU+DCDC+LDO): Usually the power module exists on the PCB as a heat source and interference source, and it is effective to add a shielding cover to it. Reduce its external radiation interference. 2. Core module (CPU+DDR+Flash[EMMC]): The core module is the core part of the PCB. Stable and undisturbed operation is an important part of the stability of the system. Modules affected by external interference are usually designed with a shielding cover to shield them. 3. Wifi and Bluetooth modules: With the continuous increase of module integration, the WiFi module also integrates many other functions, such as Bluetooth. The more integrated, Naturally, it will interfere with the reception of WiFi signals. Another main source of interference is the components on the PCB. The high-frequency circuits when they work will produce strong interference. At this time, most brand manufacturers will use shielding treatment, remove or To reduce the interference of the motherboard to the antenna, metal shields are a good choice. They can effectively shield the influence of electromagnetic waves on the internal circuit. Of course, they also block the electromagnetic waves generated inside from radiating. Of course, the location of the antenna is also more important, and it is generally placed In a relatively clean place on the side of the board, a Wifi Bluetooth module with a shielding cover was demonstrated. Mr. Deng’s company is in Chengdu, a technology company that makes WIFI modules. For various reasons, Mr. Deng is looking for a shielding cover manufacturer. According to a friend, I contacted the hardware in Dongguan. The hardware is a Dongguan shielding cover manufacturer with 15 years of experience and is familiar with the road. About an hour after Mr. Deng sent the drawings, the project accurately evaluated the feasibility of the drawings. Then The business docking was also very smooth. The work of the manual prototype was started immediately. The sample was produced in two days, and the prototype was tested OK in less than a week, and then it entered the link of mold opening. The shielding cover of the WIFI module is not very large. The time of this kind of mold can be installed in Dongguan Shield Factory in one day, and almost completed in two days. The mold sample is confirmed in one week. Then the mass production will start, from the first communication to mass production. Delivery, the total time is half a month. It greatly meets the delivery time determined by Mr. Deng and the customer. Choose hardware and respect all your needs.
