Publication number: 20230341305Abstract: A shear test is conducted on an interconnect bond formed on a surface of an electronic device by first determining a profile of the surface, and based on the determined profile, determining a shearing path which is at a substantially constant distance from the profile of the surface for a shear test tool to conduct the shear test on the interconnect bond. The shear test tool is then guided to move along the determined shearing path to measure a shear force of the interconnect bond.Type: ApplicationFiled: April 21, 2023Publication date: October 26, 2023Inventors: Keng Yew SONG, Zui Hong LEE, Jian Min CHEN, Mow Huat GOH, Kien Kia TAN

Publication number: 20230137302Abstract: An apparatus for calibrating a shear test tool utilizes a resilient pivot mechanism to improve accuracy and reliability of the force calibration. The apparatus includes a fixed element, a pivotable element configured to be rotatable relative to the fixed element, and a resilient pivot mechanism coupled between the fixed element and the pivotable element to form a pivot. The pivotable element is rotatable about the pivot to lift a weight coupled to the pivotable element when the shear test tool applies a force on the pivotable element in order to rotate the pivotable element and lift the weight.

Patent number: 9217896Abstract: A liquid crystal display comprises two parallel spaced substrates and a liquid crystal layer with negative dielectric anisotropy interposed between the substrates. The ratio d/p, the cell gap d between the substrates to the pitch p of the liquid crystal layer, is equal to or less than 0.3, and the retardation value ?n*d may be in the range of 0.25-0.4. In absence of electric field, the liquid crystal molecules are arranged vertically to the substrates, and when the sufficient electric field is applied, the liquid crystal molecules are parallel to the substrates and twisted by 90° from one substrate to the other.Type: GrantFiled: June 30, 2014Date of Patent: December 22, 2015Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Jae-Jin Lyu, Hea-Ri Lee, Kyeong-Hyeon Kim, Jian-Min Chen
