Patent ID: 7701050

Claim:
A side-view optical diode package, the side-view optical diode package being mounted on a printed circuit board with at least a solder bump, the side-view optical diode package comprising: a silicon substrate having a first surface and a second surface; a holding space having a top opening in the first surface and a bottom for holding an optical diode thereon; a bonding surface disposed at a lateral side of the silicon substrate and bonded onto the printed circuit board; a positioning structure having at least a solder-receiving portion beside the bonding surface and corresponding to the solder bump, wherein the solder bump is molten during a soldering process and received in the solder-receiving portion, thereby facilitating positioning the silicon substrate on the printed circuit board, wherein the at least a solder-receiving portion includes: a first indentation disposed at the junction between a first sidewall of the silicon substrate, the first surface of the silicon substrate and the bonding surface; a second indentation disposed at the junction between a second sidewall of the silicon substrate, the first surface of the silicon substrate and the bonding surface; a third indentation disposed at the junction between the first sidewall of the silicon substrate, the second surface of the silicon substrate and the bonding surface; and a fourth indentation disposed at the junction between the second sidewall of the silicon substrate, the second surface of the silicon substrate and the bonding surface.
