Abstract: Electrical connections are created between the actuator frame of a piezoelectric MEMS scanning mirror system and the substrate separate from the structural adhesive creating the mechanical bond between the actuator frame and the substrate. A structural bond (with no conducive properties) is formed between the actuator frame and the substrate. After the bond is fully formed, separate electric connections can be created by one or both of: 1) coating the actuator frame with a coating that enables a surface of the actuator frame to be wire bondable and creating a wire bond between the actuator frame and the substrate; or 2) depositing a trace of conductive material on the outside edge of the mechanical bond between the actuator frame and the substrate and a final protection layer may be applied over the conductive trace to protect the trace from mechanical or environmental damage.

Abstract: A system that includes a substrate for microelectromechanical system (MEMS) scanning mirror systems is provided. The MEMS scanning mirror system includes a substrate that includes a ceramic body. An actuator frame is mounted on the ceramic body of the substrate. The actuator frame includes at least one moveable member. At least one actuator is operatively connected to the at least one moveable member such that the actuator is configured to move the at least one moveable member. A scanning mirror assembly is mounted to the at least one moveable member such that movement of the at least one moveable member moves the scanning mirror assembly.

Abstract: A piezoelectric MEMS scanning mirror system is provided. In particular, the efficiency and life of the system are improved by use of new bonding methods. Mechanical and electrical connections between the actuator frame of a piezoelectric MEMS scanning mirror system and the piezoelectric actuators in the system may be created using an anisotropic conductive adhesive. An anisotropic conductive adhesive only conducts electricity across the bond line between a lower portion of the piezoelectric actuator and a top of the metal frame. One way this is done is to provide a sparse loading of conductive particles. When the piezoelectric element is compressed against the frame, the conductive particles only form a conductive path across the bond line. Grit blasting, sanding, or chemical etching may be used to roughen the metal surface prior to bonding. A surface roughness between 2 RMS and 6 RMS may be created on the metal frame.
