A flash memory device includes a Chip-On-Board (COB) type circuit board and a number of first and second contacts electrically connected to the circuit board. Each first contact includes a stiff first contact portion formed on an upper surface of the circuit board. Each second contact includes a cantilevered planar second contact portion extending along the front-to-rear direction. When the flash memory device is inserted into a USB 3.0 receptacle connector, the first and the second contact portions jointly electrically connect with the USB 3.0 receptacle connector. The planar second contact portions provide larger contacting area for mating with the corresponding contacts of the USB 3.0 receptacle connector.

Flash memory device and assembly thereof with improved planar contact portions

A flash memory device includes a circuit board and a contact module slidable with respect to the circuit board. The circuit board includes a plurality of first contacts each having a stiff first contact portion. The contact module includes a slider and a plurality of second contacts fixed to the slider. The slider is slidable with respect to the circuit board along a front-to-rear direction between a first position and a second position. The flash memory device is compatible to USB 2.0 and USB 3.0 receptacle connectors via the slidable contact module.
