Electronic device package
摘要:
An electronic device (300), such as an integrated circuit chip or a multichip module, is held in place overlying a circuit board (200) with which it is thermal expansion mismatched by means of three or more localized rigid support elements (243,253; 244,254; 245,255). The bottom surface of the chip is bonded to the top surface of preferably only one of these support elements (244,254) and can laterally slide along the top surfaces of the others in response to heating and cooling during electrical operations of the electronic device. In addition, the electronic device is encapsulated in a soft gel (400) that is held in place by means of a rigid plastic half-shell cover (500) that is epoxy-bonded in place along its perimeter (edge).
