Publication number: 20140312501Abstract: Structures and manufacturing processes of an ACF array using a non-random array of microcavities of predetermined configuration, shape and dimension. The manufacturing process includes fluidic filling of conductive particles onto a substrate or carrier web comprising a predetermined array of microcavities, of selective metallization of the array followed by filling the array with a filler material and a second selective metallization on the filled microcavity array. The thus prepared filled conductive microcavity array is then over-coated or laminated with an adhesive film. Cavities in the array, and particles filling the cavities, can have a unimodal, bimodal, or multimodal distribution.Type: ApplicationFiled: May 20, 2014Publication date: October 23, 2014Applicant: TRILLION SCIENCE INC.Inventors: Rong-Chang Liang, Hsiao-Ken Chuang, Jerry Chung, Chin-Jen Tseng, Shuji Rokutanda, Yuhao Sun

Patent number: 8551391Abstract: A method of making a microneedle array structure (20) comprising a plurality of simultaneously formed microneedles (24), each microneedle (24) having a protrusion (32) and a passageway (34) extending therethrough. The method comprises the steps of pressing an embossable sheet material between a complimentary tools and radiantly heating the sheet material using radiant energy from a radiant energy source. One tool is relatively-radiantly-transparent, and another tool and/or the sheet material is relatively-radiantly-absorptive.Type: GrantFiled: February 3, 2005Date of Patent: October 8, 2013Assignee: Avery Dennison CorporationInventors: Eng-Pi Chang, Philip Yi Zhi Chu, Hsiao Ken Chuang, Kejian (Kevin) Huang, Michael Lang, Reza Mehrabi, Ronald F.

Publication number: 20110253943Abstract: An adhesive composition comprising: (i) a one part curable epoxy adhesive and (ii) a low profile additive (LPA), the low profile additive being a polymer that is compatible with the epoxy adhesive such that it forms a single phase when admixed with the adhesive composition and that separates from the adhesive to form a network of stress-absorbing nodules therein when the adhesive is cured, the low profile additive being present in an amount sufficient to prevent or reduce shrinkage and/or the formation of voids or cracks when the adhesive is cured. In one embodiment the LPA is a block copolymer including at least one flexible block and at least one rigid block that makes the low profile additive compatible with the epoxy adhesive such that a mixture of the uncured epoxy resin and the low profile additive forms a homogenous solution and as the epoxy resin is cured, the low profile additive forms a stress absorbing network of nodules in the cured epoxy resin matrix.Type: ApplicationFiled: April 19, 2010Publication date: October 20, 2011Applicant: TRILLION SCIENCE, INC.Inventors: Rong-Chang Liang, Yuhao Sun, Hua Song, Chin-Jen Tseng, Hsiao Ken Chuang

Patent number: 7416692Abstract: A method of embossing a sheet material includes: heating at least a portion of the sheet directly or indirectly with radiant energy from a radiant energy source; pressing a tool against the heated portion of the sheet, thereby patterning a surface of the sheet; and separating the sheet and the tool. The radiant energy may travel through a solid material that is relatively transparent to radiation, on its way to being absorbed by a relatively-absorptive material. The relatively-transparent material may be an unheated portion of the sheet, and the relatively-absorptive material may be either the tool or the heated portion of the sheet. Alternatively, the relatively-transparent material may be the tool, and the relatively-absorptive material may be all or part of the sheet. The method may be performed as one or more roll-to-roll operations.Type: GrantFiled: January 31, 2005Date of Patent: August 26, 2008Assignee: Avery Dennison CorporationInventors: Rishikash K. Bharadwai, Eng-Pi Chang, Philip Yi Zhi Chu, Hsiao Ken Chuang, David N. Edwards, Robert J. Fermin, Ali R. Mehrabi, Reza Mehrabi, Ronald F. Sieloff, Chunhwa Wang
