Laser power control manufacturing method of matching binned laser to drive conditions through soldering and component mounting techniques to convey binning information

A method for programming a function of an optical mouse during assembly, comprising:

• mounting a resistor on a printed circuit board, the resistor being indicative of a parameter of the function;
• mounting an optical mouse controller on the printed circuit board, the optical mouse controller being electrically coupled to the resistor;
• mounting an optical mouse sensor on the printed circuit board;
• electrically coupling a laser to the optical mouse sensor to receive a drive current;
• wherein during startup of the optical mouse, the optical mouse controller senses the resistor and programs the parameter into the optical mouse sensor to drive the laser accordingly.

An optical mouse, comprising:

• a printed circuit board;
• an optical mouse sensor mounted on the printed circuit board;
• a laser electrically coupled to the optical mouse sensor to receive a drive current;
• and
• a resistor mounted on the printed circuit board, wherein the resistor indicates a parameter of a function to be programmed into the optical mouse sensor for driving the laser.
