Traditional Shielding Case method：
In order to block the electromagnetic wave (EMI) of the wireless communication device and increase the receiving sensitivity, the upper cover and the bracket are used to cover the IC, and the same outer bracket is directly soldered to the PCB to fix the upper cover.
Current Shield Can Clip method：
Using a standardized and miniaturized Clip, it can be attached to the PCB in the shape of the cover regardless of the shape of the cover.
Comparison of the two methods：
Clip main features：
1. PCB space is easy to use
2. Improve SMD production efficiency
3. Cost saving (do not have to open Frame mold)
4. Convenient maintenance
5. All models can be shared
6. Reduce development time
7. Easy to purchase, reduce the cost of managing inventory
8. Realize ultra-thin product
