  • Publication number: 20150258750
    Abstract: A glass-polymer laminate structure includes a flexible glass substrate having a thickness of no more than about 0.3 mm. A polymer layer is laminated to a surface of the flexible glass substrate having a coefficient of thermal expansion (CTE) that is at least about 2 times a CTE of the flexible glass substrate. The polymer layer is laminated to the surface of the flexible glass substrate after thermally expanding the polymer layer to provide the flexible glass substrate with an in-plane compressive stress of at least about 30 MPa along a thickness of the flexible glass substrate.

  • Publication number: 20150183186
    Abstract: Methods of processing a glass substrate comprise the step of obtaining a glass substrate and a tab removably attached to a portion of the glass substrate. The position of the glass substrate is manipulated with the engagement portion and the tab is removed from the portion of the glass substrate by releasing a mounting portion of the tab from the portion of the glass substrate without damaging the glass substrate. In further examples, methods include the steps of removably attaching first and second tabs to respective first and second surfaces of a glass substrate and coiling the glass substrate on a storage roll wherein the first tab adheres to the second tab. In further examples, a glass apparatus comprises a glass substrate and a removable tab including a mounting portion attached to a portion of the glass substrate with a first peel force of less than about 10 N/cm.

  • Patent number: 8585280
    Abstract: A method of manufacturing a microfluid mixer includes pouring a ceramic precursor into a first mold, a second mold and a third mold. The first mold forms a base plate, the second mold forms a top plate, and the third mold forms a first plate. The ceramic precursors are gelled in the first mold, the second mold and the third mold to form a green base plate, a green top plate and a green first plate. The plates are removed from the respective molds. The green base plate, the green top plate, and the green first plate are co-fired to form a ceramic base plate, a ceramic top plate and a ceramic first plate. The ceramic base plate is interlocked with the ceramic top plate and the ceramic first plate, and a diaphragm is disposed upon one of the first plate and the top plate.

  • Patent number: 7992627
    Abstract: Low-pressure drop thermal assemblies, systems and methods of making low-pressure drop thermal assemblies for use in high power flux situations. A manifold body is attached to a distributor to form a subassembly. This subassembly is in communication with a substrate surface, which has a semiconductor device in need of thermal management thereon. An enclosed cavity is formed between the target substrate surface and the subassembly, and a seal of the cavity protects critical components residing on the active surface of the semiconductor device. The distributor includes a distributed liquid impingement microjet inlet array isolated from and parallel with a distributed microjet drain array for impinging cooling fluid and removing spent heated fluid in a direction orthogonal to a target surface for maximizing the heat transfer rate, and thereby providing high cooling flux capabilities while enabling low-pressure drops.
