MEMS snubber systems and methods

摘要

Techniques are disclosed for systems and methods to provide concomitant mechanical motion inhibition and electrical distribution for actuator modules, such as microelectromechanical systems (MEMS) based optical actuators adapted to move and/or orient one or more lenses and/or optical devices of a camera module. A mechanical motion inhibition and electrical distribution system may include one or more flexible snubber structures disposed substantially adjacent a MEMS structure and between the MEMS structure and another component of a camera module. Each flexible snubber structure may be implemented with one or more electrical traces, flexible films, snubber films, and/or mechanical stabilizers adapted to route electrical signals to or from the MEMS structure and/or to inhibit mechanical motion of at least a portion of the MEMS structure.

主权项

1. A flexible snubber structure, comprising:
a ribbon portion comprising one or more electrical traces, wherein the electrical traces are at least partially electrically insulated by a ribbon film; a substantially planar snubber portion comprising a plurality of mechanical stabilizers embedded in a snubber film; and a folding portion coupling the ribbon portion to the snubber portion, wherein at least one of the mechanical stabilizers is electrically conductive, and wherein corresponding ones of the electrical traces are electrically coupled to the electrically conductive mechanical stabilizers.
