Patent number: 7323364Abstract: A combination composed from a form standard and a CSP is attached to flex circuitry. Solder paste is applied to first selected locations on the flex circuitry and adhesive is applied to second selected locations on the flex circuitry. The flex circuitry and the combination of the form standard and CSP are brought into proximity with each other. During solder reflow operation, a force is applied that tends to bring the combination and flex circuitry closer together. As the heat of solder reflow melts the contacts of the CSP, the combination collapses toward the flex circuitry displacing the adhesive as the solder paste and contacts merge into solder joints. In a preferred embodiment, the form standard will be devised of heat transference material, a metal, for example, such as copper would be preferred, to improve thermal performance. In other embodiments, the methods of the invention may be used to attach a CSP without a form standard to flex circuitry.Type: GrantFiled: April 25, 2006Date of Patent: January 29, 2008Assignee: Staktek Group L.P.Inventors: Julian Partridge, James Douglas Wehrly, Jr., David Roper

Publication number: 20070290302Abstract: In a liquid crystal driver package (1a) of one embodiment of the present invention, a film base member (2) is connected to a liquid crystal driver (3) through an interposer substrate (4a). Film base member connecting terminals (13) of the interposer substrate (4a) are connected to terminals of on-film wires (5 and 6) of the film base member (2) with an anisotropic conductive adhesive. An insulating film (7) is formed at an edge section of the interposer substrate (4a) and a periphery section of the edge section. This arrangement prevents the on-film wires (5 and 6) from coming into direct contact with the interposer substrate (4a). Therefore, it becomes possible to provide an IC chip (liquid crystal driver) package in which short circuit does not occur between the on-film wires adjacent to each other.Type: ApplicationFiled: June 13, 2007Publication date: December 20, 2007Inventors: Tomokatsu Nakagawa, Yasunori Chikawa, Setsunobu Wakamoto, Tatsuya Katoh, Satoru Kudose
