Abstract:
1. An electro magnetic (EM) wave shielding device, adapted to cover a test point region of a circuit board, wherein the circuit board is disposed in a case, and the test point region of the circuit board generates an EM wave, the EM wave shielding device comprising: at least one metal plate; and at least one EM wave absorbing material, configured on a lateral side of the metal plate; wherein the lateral side of the metal plate configured with the EM wave absorbing material covers the test point region, thereby absorbing and shielding the EM wave, a plurality of fixing holes is formed on positions of the circuit board adjacent to the test point region, the metal plate has a plurality of via holes corresponding to the fixing holes, and a plurality of fixing parts pass through the via holes and the fixing holes, so as to fix the metal plate on the circuit board.
