    • In a bonding station the parts of the apparatus to be bonded are retained at a thermal bias temperature at a permitted level and a thermal check valve interface is provided between the bonding location and the part of the station that would serve as a conduction heat sink, thereby thermally insulating other uninvolved parts of the structure and and confining the bonding heat to the bonding region. Such confinement reduces the dwell time that the bond must remain at the bonding temperature. The bonding station has a number of features: the parts to be bonded are maintained on a support member that is provided with a heat biasing capability that can establish the assembly at a specified temperature; a retention capability, such as the use of vacuum, is provided to maintain registration and thermal contact of the part with the support; and a thermal check valve capability is provided to control the rate of heat flow through the support member so that locallized heat is controlled in dissipation.
    • 在接合站中,要被接合的设备的部件被保持在允许的水平的热偏压温度,并且在用作传导散热器的接合位置和站的部分之间提供热止回阀接口, 从而将结构的其它未掺杂部分进行绝热并且将结合热限制到接合区域。 这种限制减少了粘合在粘合温度下必须保持的停留时间。 粘合台具有许多特征:待粘合的部件被保持在具有可在规定温度下建立组件的热偏置能力的支撑部件上; 提供保持能力,例如使用真空,以保持部件与支撑件的配准和热接触; 并且提供热止回阀能力以控制通过支撑构件的热流的速率,从而控制局部放热的散热。
