PRINTED CIRCUIT BOARD FOR SOLID STATE RECORDER TELEMETRY DATA DRIVE WHICH RAPIDLY RELEASES HEAT CREATED FROM INTERNAL UNIT TO OUTSIDE BY FORMING THERMAL DISSIPATION PATTERN INSIDE THE PRINTED CIRCUIT BOARD CONNECTED TO HEAT GENERATION ELEMENT OF SOLID STATE RECORDER TELEMETRY DATA DRIVE

摘要

PURPOSE: By being efficiently proceed the radiant heat action without the separate apparatus like the cooling pen through the printed circuit board the printed circuit board for the solid state recorder telemetry data drive reduces the whole size of the solid state recorder telemetry data drive.;CONSTITUTION: A ground layer(130) is connected to the ground terminal of the semiconductor device mounted on the printed circuit board. A first thermal dissipation pattern(140) is connected to the ground layer. A first internal layer copper bump(150) is connected to the first thermal dissipation pattern. A Vcc layer(170) is connected to the Vcc terminal of the semiconductor device mounted on the printed circuit board. It is contiguous to the Vcc layer and the buffer layer is formed inside the printed circuit board.;COPYRIGHT KIPO 2010
