摘要

在新的微带设计中,芯片直接连接到镀金的铜或黄铜载体上,该载体与翅片铝散热器密切热接触。这导致“未吹”热阻为3。S°C/瓦特和“吹”的Rth为1.6 oc /瓦特。

A Microstrip Fixture Design for Power GaAs Fets
Small signal,(low power) devices can very adequately be In the new microstrip design the chip is die attached directly to a gold plated copper or brass carrier which is in intimate thermal contact with a finned aluminum heat sink. This results in an "unblown" thermal resistance of 3.S°C/Watt and a "blown" Rth of 1,6OC/Watt.
