An electronic device includes a circuit board, a shielding member, and a testing pin. The circuit board includes a grounding area. The shielding member is located on a side of the circuit board and includes a shielding layer and an insulating layer. The shielding layer is electrically connected to the grounding area. The insulating layer is located on a side of the shielding layer away from the circuit board. The testing pin is disposed on the circuit board and electrically connected to the shielding layer.

Electronic device

A supported amorphous alloy catalyst, which is supported on a macroporous carrier-expanded graphite. The catalyst contains a Ni&#x2014;B amorphous alloy (5 to 50% by weight) and a transition inductive metal (0.1 to 10% by weight). The diameter of expanded graphite carrier particles is 80-800 &#x3bc;m. Its BET specific surface area is 10-100 m/g. The catalyst is prepared by metal inductive electroless powder plating method which is easy to apply to industrial production. Ni&#x2014;B clusters of prepared catalyst are well dispersed on the support. The catalyst shows high catalytic activity and good mechanical property, and is safe to use with low manufacturing costs.
