Abstract:
The invention relates to an insonification device (100) comprising a plurality of elementary ultrasonic transducers (110) each comprising at least one electro-acoustic element (111) and distributed on a chassis (120, 140) so that the electro-acoustic elements (111) are distributed on a so-called front surface (120′) of the device (100) intended to be placed facing the medium to be insonified. According to the invention, as each transducer (110) comprises a longitudinal body (113) made in a heat conducting material at the so-called front end of which the electro-acoustic element (111) is placed, the chassis (120, 140) comprises a sealed cooling chamber (130) placed behind the front surface (120′), crossed by the bodies of the transducers (113) and intended to be gone through by a coolant fluid flow.

Abstract:
A method of assembling a bent circuit chip package and a circuit chip package having a bent structure. The circuit chip package includes: a substrate having a first coefficient of thermal expansion (CTE); a circuit chip, having a second CTE, mounted onto the substrate; a metal foil disposed on the circuit chip in thermal contact with the chip; a metal lid having (i) a third CTE that is different from the first CTE and (ii) a bottom edge region, where the metal lid is disposed on the metal foil in thermal contact with the metal foil; and an adhesive layer along the bottom edge of the metal lid, cured at a first temperature, bonding the lid to the substrate, producing an assembly which, at a second temperature, is transformed to a bent circuit chip package.
