Abstract: Arrays of solder interconnections between a semiconductor device (10) and a supporting substrate (12) are annealed for a time in excess of one or several days below the solder melting temperature to relief stress and improve the fatigue failure of the interconnections.

Abstract: An apparatus (10) for reflowing solder terminals (22) that join an electronic element (20) to a substrate (16) which includes a stage for supporting the substrate, a quantity of fluid capable of being heated to a temperature in excess of the melting point of the solder to be reflowed, a means to contact the surface of the substrate with the fluid, the means including at least one reservoir for maintaining fluid at a temperature in excess of the melting point of the solder, and a pumping means to move the fluid from the reservoir into contact with the surface of the substrate. A method of reflowing solder terminals that join an electronic device to a substrate that includes the steps of contacting the bottom surface of the substrate with a fluid, rapidly increasing the temperature of the fluid to a temperature exceeding the melting point of the solder material of the solder terminal, and subsequently rapidly decreasing the temperature of the fluid.

Abstract: A flexible, extensible thermal conduction element for use in a semiconductor package to conduct heat from a device to a cold plate or cover, featuring a plurality of thin flexible interleaved leaf elements (36, 42) capable of bridging the gap between the device and cold plate, and accommodating for gap variability and non-parallel surfaces. Two sets of bolted together (40), spaced, interleaved, flexible elements are biased by spring means (60) away from each other to form a thermal conduction element.
