How do you manufacture an SD card?
IC chips, including a MicroSD controller chip and a flash memory chip, are attached to the PCB by wire bonding or other chip-on-board (COB) technique. A molded layer is then formed over the IC chips and passive components using a mold that prevents formation of plastic on the upper surface of each PCB.
