Precision micromirror positioning

A method of aligning a micromirror array to a display system, the method comprising:

• providing a package substrate, said package substrate having at least two edges and one surface;
• aligning said package substrate along an y axis by contacting said package substrate in two predefined regions along a first edge;
• aligning said package substrate along an x axis by contacting said package substrate in one predefined region along a second edge;
• aligning said package substrate along a z axis by contacting said package substrate in three predefined regions along a first surface, said x, y, and z axes being orthogonal and said first surface being parallel to said x and y axes;
• attaching a micromirror at a predetermined position on said package substrate;
• attaching a cover to said package substrate to enclose said micromirror;
• providing a display system having a socket to hold said micromirror;
• and
• placing said package substrate in said socket such that said socket aligns said package substrate by contacting said package substrate in said two predefined regions along said first edge, said one predefined region along said second edge, and said three predefined regions along said first surface.

A method of mounting a micromirror array on a package substrate, the method comprising:

• providing a package substrate, said package substrate having at least two edges and one surface;
• aligning said package substrate along an y axis by contacting said package substrate in two predefined regions along a first edge;
• aligning said package substrate along an x axis by contacting said package substrate in one predefined region along a second edge;
• and
• attaching a micromirror at a predetermined position on said package substrate.

A method of mounting a micromirror array in a display system, the method comprising:

• providing a micromirror array in a package, said package having at least two edges and one surface;
• aligning said package along an y axis by contacting said package substrate in two predefined regions along a first edge;
• and
• aligning said package along an x axis by contacting said package in one predefined region along a second edge.
