Dongguan shielding cover manufacturers tell you how important the heat dissipation holes of the shielding cover are [hardware]

The seven or eight-hour high-speed rail journey from Beijing to Dongguan makes Mr. Liu feel more like an ant on a hot pot. Two months ago, their family asked friends to introduce shield manufacturers, and then met with Qunge's family. A shielding cover applied to the module requires full stretching and no gaps in the whole after welding. There was no problem in the proofing test and the small batch trial production. However, when there is a problem, it is a big problem. The first batch of orders was placed in 3K small batch production. There were less than 200 patches, and suddenly there was a bang, and a piece of PCB board exploded directly on the SMT workbench. The reason is that this fully enclosed shield can not discharge the high temperature generated during welding, bursting the main board and bursting the components. In fact, the principle of the shielding cover, whether it needs to be fully enclosed or semi-enclosed, has a lot to do with the original device used. If you want to know more about shield manufacturers, you are welcome to pay attention to Qunge: Let's discuss more industry knowledge together!
