What issues should we pay attention to in the interface of the shielding box?

1. The external size of the interface must match the opening size of the shielding box, because if the size deviation is too large, the signal will run out of the gap, resulting in no shielding effect or poor shielding effect.

2. The interface is generally made of aluminum, which has good conductivity and magnetic insulation. When installing the interface, the circuit board part needs to be treated with insulation tape on the interface circuit board. The price of the wireless shielding box is to avoid short circuit caused by contact with the interface

3. When the interface assembly is completed, use a multimeter to check for short circuits.
