Patent ID: 8481103

Claim:
A method of dispensing comprising: providing a first surface adapted to at with a second surface, and a flowable substantially heat-conducting interlace material adapted to form a layer between the first surface and second surface to conduct heat; depositing the interface material on the first surface in an optimized deposition pattern comprising a plurality of discrete regions of interface material which are respective separated by gas within gas flow passages, each region comprising locations of interface material and a respective amount of interface material at each respective location being optimized according to an output of at least one automated processor executing a computational flow dynamics model responsive to at least the first surface, the second surface, and the deposition pattern and physical properties of the interface material; and compressing the first and second surfaces, to spread out the discrete regions of the interface material, the position pattern being optimized to form a thin contiguous final layer of interface material substantially without trapped gas between the first surface and the second surface as a result of compression to a terminal thickness limited based on a shear yield stress of the interface material, the patency of the gas flow passages being maintained during compression and then collapsing just prior to when the thin contiguous final layer achieves a terminal thickness, wherein the deposition pattern of interface material is further optimized by the at least one automated processor executing a computational flow dynamics model according to one or more criteria selected from the group consisting of processing time, peak squeezing force, average squeezing force, squeezing force profile, thermal conductivity, operating temperature, prescribed thermal conductivity as a function of location, prescribed normal operating temperature as a function of location, peak operating temperature as a function of location, cost, cost-benefit and yield.
