Patent ID: 7874067

Claim:
A method of fabricating flash memory devices, the method comprising: providing a PCB (printed circuit board) panel having a plurality of PCB boards disposed in an N×M matrix such that the plurality of PCB boards can be separated with one or more single directional cuts, wherein each PCB corresponds to a single chip COB (chip-on-board) USB (universal serial bus) memory device to be manufactured; performing an SMT (surface mount technology) process on the PCB panel to place one or more passive electronic components of a single chip COB USB memory device on a bottom surface of each PCB board, the one or more passive electronic components including at least one resister, capacitor, optional LED (light emitting diode), and oscillator; performing a die bonding process to place one or more active electronic components of a single chip COB USB memory device on the bottom surface of each PCB board, the one or more active electronic components including a flash memory controller die and a flash memory die; performing a wire bonding process to place electrical connections among the active and passive components of a single chip COB USB memory device on each PCB board; performing an encapsulation process to encapsulate the active and passive electronic components of each PCB board to form an individual single chip COB USB memory device, using a transfer or injection molding process on the bottom surface of each PCB board which exposes a top surface of each PCB board with a plurality of metal contacts for physical and electrical contact with metal pads of a host interface socket when inserted.
