ULTRASOUND TRANSDUCER FEATURING A PITCH INDEPENDENT INTERPOSER AND METHOD OF MAKING THE SAME
摘要
An ultrasound transducer 10 comprises an application specific integrated circuit (ASIC) 14, an array of acoustic elements 20, and a pitch independent interposer 12. The ASIC 14 includes a plurality of contact pads 16 on a surface of the ASIC that are separated from adjacent ones thereof by a first pitch. The acoustic elements 22 of the array 20 are separated from adjacent ones thereof by a second pitch. In addition, the pitch independent interposer 12 features a plurality of conductive elements 26 separated from adjacent ones thereof by a third pitch different from both the first pitch and the second pitch. The pitch independent interposer 26 is electrically coupled (i) on a first side to the ASIC via a first subset of the plurality of conductive elements and (ii) on a second side to the array of acoustic elements via a second subset of the plurality of conductive elements, wherein one or more of the plurality of conductive elements 26 electrically couples a contact pad 16 of the ASIC 14 with a corresponding acoustic element 22 of the array 20 of acoustic elements.
