Methods for manufacturing glass articles having a target effective coefficient of thermal expansion CTEaveraged over a temperature range comprise selecting a glass core composition having an average core glass coefficient of thermal expansion CTEthat is greater than the target effective CTEand a glass clad composition having an average clad glass coefficient of thermal expansion CTEthat is less than the target effective CTE; and manufacturing a glass laminate comprising a glass core layer formed from the glass core composition and two or more glass cladding layers fused to the glass core layer, each of the two or more glass cladding layers formed from the glass clad composition such that a ratio of a thickness of the glass core layer to a total thickness of the two or more glass cladding layers is selected to produce the glass laminate having an effective coefficient of thermal expansion CTEthat is within ±0.5 ppm/° C. of the target effective CTE.

Glass carriers for fan-out packaging having target coefficients of thermal expansion and methods for making the same

A system includes an overflow distributor () including a weir (). The system further includes a thermal exchange unit positioned in proximity to the weir. The thermal exchange unit () includes a tubular focusing member () and a thermal member () disposed at least partially within a lumen of the focusing member. The focusing member extends distally beyond a distal end of the thermal member by a distance It. In an embodiment the thermal exchange unit comprises several focusing members and thermal members to control a thermal profile of a glass stream flowing over the weir, particularly of a portion of the glass stream in contact with the weir.

Method and apparatus for controlling thickness of glass sheet

Methods of producing a glass sheet comprise the step of fusion drawing a glass ribbon along a draw direction into a viscous zone downstream from a root of a forming wedge. The method further includes the steps of drawing the glass ribbon into a setting zone downstream from the viscous zone and an elastic zone downstream from the setting zone. The method also includes the step of creating a vacuum to force the entire lateral portion of the glass ribbon to engage an anvil portion of a breaking device in the elastic zone. The method still further includes the steps of forming a score line along the lateral portion of the glass ribbon and breaking away a glass sheet from the glass ribbon along the score line while the entire lateral portion is forced against the anvil portion by the vacuum.
