Patent number: 7626273Abstract: The present invention provides a system and method that mounts integrated circuit devices onto substrates and a system and method for employing the method in stacked modules. The contact pads of a packaged integrated circuit device are substantially exposed. A solder paste that includes higher temperature solder paste alloy is applied to a substrate or to the integrated circuit device to be mounted. The integrated circuit device is positioned to contact the contacts of the substrate. Heat is applied to create high temperature joints between the contacts of the substrate and the integrated circuit device resulting in a device-substrate assembly with high temperature joints. The formed joints are less subject to re-melting in subsequent processing steps. The method may be employed in devising stacked module constructions such as those disclosed herein as preferred embodiments in accordance with the invention. Typically, the created joints are low in profile.Type: GrantFiled: January 20, 2009Date of Patent: December 1, 2009Assignee: Entorian Technologies, L.P.Inventors: Julian Partridge, James W. Cady, James Wilder, David L. Roper, James Douglas Wehrly, Jr.

Publication number: 20090273069Abstract: The present invention stacks chip scale-packaged integrated circuits (CSPs) into low profile modules that conserve PWB or other board surface area. Low profile structures provide connection between CSPs of the stacked module and between and to the flex circuitry. Low profile contacts are created by any of a variety of methods and materials including, for example, screen paste techniques and use of high temperature solders, although other application techniques and traditional solders may be employed for creating low profile contacts in the present invention. A consolidated low profile contact structure and technique is provided for use in alternative embodiments of the present invention. The CSPs employed in stacked modules devised in accordance with the present invention are connected with flex circuitry. That flex circuitry may exhibit one or two or more conductive layers.Type: ApplicationFiled: May 7, 2009Publication date: November 5, 2009Inventors: James W.

Patent number: 7606048Abstract: The present invention stacks packaged integrated circuits into modules that conserve PWB or other board surface area. The present invention can be used to advantage with packages of a variety of sizes and configurations ranging from larger packaged base elements having many dozens of contacts to smaller packages such as, for example, die-sized packages such as DSBGA. In a preferred embodiment devised in accordance with the present invention, a base element CSP integrated circuit and a support element CSP integrated circuit are aggregated through a flex circuit having at least two conductive layers that are patterned to selectively connect the two CSP elements. A portion of the flex circuit connected to the support element is folded over the base element to dispose the support element above the base element while reducing the overall footprint.

Patent number: 7495334Abstract: The present invention stacks chip scale-packaged integrated circuits (CSPs) into modules that conserve PWB or other board surface area. In a two-high CSP stack or module devised in accordance with a preferred embodiment of the present invention, two CSPs are stacked, with one CSP disposed above the other. The two CSPs are connected with flex circuitry. A form standard is disposed between the flex circuitry and a CSP in the stack. The form standard can take many configurations and may be used where flex circuits are used to connect CSPs to one another in stacked modules having two or more constituent CSPs. For example, in stacked modules that include four CSPs, three form standards are employed in preferred embodiments, although fewer may be used. The form standard provides a thermally conductive physical form that allows many of the varying package sizes found in the broad family of CSP packages to be used to advantage while employing a standard connective flex circuitry design.Type: GrantFiled: August 4, 2005Date of Patent: February 24, 2009Assignee: Entorian Technologies, LPInventors: Russell Rapport, James W.
