    摘要： A specialized tool is provided for the removal of components in a microwave module in which a fixed tool having a channeled tip is positioned adjacent the component to be removed. A hot stream of gas, in one embodiment nitrogen, is then forced through the channel onto the top surface of the component to be removed, with the microwave module lying on a heated platen, such that the local increase in temperature at the component to be removed is enough hotter than the ambient temperature of the module as determined by the heated platen to soften the silver epoxy used to mount the component to the module without damaging nearby components. With the fixed tool adjacent the component to be removed and with the component provided with targeted heating, the module is moved against the tool to cause a shear force that moves the component away from its original position, thus breaking the epoxy bond, after which the component is plucked from the module. The subject tool and technique eliminates collateral damage associated with the use of a ball peen hammer and chisel, and results in a tenfold decrease in rework time.
