Apparatus for shaping transducer membranes

摘要

The present disclosure provides a transducer shaping chamber for shaping ultrasound transducers. The transducer shaping chamber includes a transducer coupon carrier having one or more slots. The one or more slots each are geometrically shaped to hold a transducer coupon having a plurality of ultrasonic transducers formed thereon. The transducer shaping chamber includes a first plate disposed over a first side of the transducer coupon carrier. The transducer shaping chamber includes a second plate disposed over a second side of the transducer coupon carrier. The second side is opposite the first side. The transducer shaping chamber is configured to move the first plate and the second plate toward each other so as to push against the transducer coupon carrier from the first and second sides, respectively, until the transducer coupon carrier has been sealed against the first plate and with the second plate.

主权项

1. A system for fabricating an ultrasound transducer, the system comprising:
a control panel that includes a plurality of control mechanisms configured to set a plurality of fabrication process parameters, the fabrication process parameters being selected from the group consisting of: process pressure, process time, process duration, and process voltage; and a transducer shaping chamber communicatively coupled to the control panel and configured to implement the fabrication process parameters therein in response to instructions from the control panel, the transducer shaping chamber including:
a removable part carrier configured to load a transducer coupon having a plurality of transducers formed thereon, the transducers each having a transducer membrane disposed over a well partially filled with an epoxy;a first plate configured to support and seal against the part carrier from a first side, the first plate facing the transducer well; anda second plate configured to support and seal against the part carrier from a second side opposite the first side, the second plate facing toward the transducer membrane;wherein:the first and second plates are configured to be moved toward each other until the part carrier is sealed between the first plate and the second plate; andthe transducer shaping chamber is configured to deflect the transducer membrane into an arcuate shape through application of pressurized air.
