Abstract: The electronic card connector of the present invention comprises an isolation chassis and a pair of metallic arms. The isolation chassis is made of an insulation material. The isolation chassis comprises a plurality of conductive terminals. A metallic arm is respectively fixed onto each of two ends of the isolation chassis. Each of the metallic arms extends downwardly and has a grounding portion and a welding portion for welding securely to the circuit board. Before attaching the electronic card connector to the circuit board, the welding portion of the metallic arm, which has a low melting point conductive metal, reduces the vertical height on the circuit board, when it gets liquefied due to heat in the convection reflow oven, and thus the connecting point on the circuit board and the welding portion of the metallic arm are electrically connected through the solder.
