    摘要: A method for forming a high thermal conductivity heat sink to IC package interface is disclosed. The method uses reactive getter materials added to a two phase solder system having a phase change temperature that is about the normal operating temperature range of the IC, to bind absorbed and dissolved oxygen in the two phase solder interface material at or near the air to solder surface. Over time this chemical binding action results in an oxide layer at the air to solder surface that slows the rate of oxygen absorption into the solder interface material, and thus reduces the harmful oxidation of the solder to IC package interface and the solder to heat sink interface.

    摘要: In some example embodiments, a method includes engaging a first contact on a motherboard with a second contact on an electronic package. A portion of one of the first and second contacts is covered with an interlayer that has a lower melting temperature than both of the first and second contacts. The method further includes bonding the first contact to the second contact by melting the interlayer to diffuse the interlayer into the first and second contacts. The bonded first and second contacts have a higher melting temperature than the interlayer before melting. In other example embodiments, an electronic assembly includes a motherboard having a first contact that is bonded to a second contact on an electronic package. An interlayer is diffused within the first and second contacts such that they have a higher melting temperature than the interlayer before the interlayer is diffused into the first and second contacts.

    摘要: High strength, reliable bulk metallic glass (BMG) solder materials formed from alloys possessing deep eutectics with asymmetric liquidous slopes. BMG solder materials are stronger and have a higher elastic modulus than, and therefore are less likely than crystalline solder materials to damage fragile low k interlayer dielectric (ILD) materials due to thermal stress in materials with different coefficients of thermal expansion (CTE). BMG solder materials may physically, electrically, or thermally couple a feature to another feature, or any combination thereof. For example, in an embodiment of the invention, a BMG solder material may physically and electrically couple an electronic component to a printed circuit board. In another embodiment of the invention, a BMG solder material may physically and thermally couple an integrated heat sink to a semiconductor device. Many embodiments of a BMG solder material are also lead-free, so they comply with lead-free product requirements, while providing a better solution than other lead-free solder materials such as tin-silver-copper.
