Abstract
The present invention discloses a structure of a single-sided PCB within an ExpressCard with SMD LEDs arrangement formed thereon. The SMD LEDs are act as status indicators for the electronic devices with small, thin and compact size. The structure is expected to form SMD LED illuminating light to the top surface of the PCB with SMD LEDs connecting to the bonding pads on the bottom surface of the PCB. The method comprises forming through-holes on the PCB, placing SMD LEDs over the through-holes with their illuminating heads facing toward the top surface of the PCB, soldering the SMD LEDs with the bonding pads on the bottom surface of the PCB.
Claims9
An ExpressCard with surface-mount device light emitting diodes mounted therein, comprising:
- a printed circuit board positioned within said ExpressCard having a plurality of through holes;
- a top cover of said ExpressCard having a plurality of status icons formed thereon;
- a bottom cover of said ExpressCard clasping said top cover;
- and
- said plurality of surface-mount device light emitting diodes bonding with said printed circuit board over said plurality of through holes and beneath said plurality of status icons.
A method of forming surface-mount device light emitting diodes on a printed circuit board within an ExpressCard, comprising:
- forming a plurality of through holes at the position between two adjacent bonding pads on said printed circuit board;
- placing said surface-mount device light emitting diodes over said through holes on the bottom surface of said printed circuit board with a plurality of illuminating heads of said surface-mount device light emitting diodes facing and extending to the top surface of said printed circuit board through said through holes;
- and
- implementing a soldering process for bonding cathode contacts of said surface-mount device light emitting diodes with said adjacent bonding pads on the bottom surface of said printed circuit board.
