Patent number: 9671671Abstract: An optical assembly may include a substrate, a housing carried by the substrate and having at least one adhesive-receiving recess in an upper surface thereof, and a lens carried by the housing. The optical assembly may also include a liquid crystal focus cell adjacent the lens and including cell layers and pairs of electrically conductive contacts associated therewith. The optical assembly may also include at least one electrically conductive member within the at least one adhesive-receiving recess and coupling together each pair of the electrically conductive contacts, and an adhesive body in the at least one adhesive-receiving recess covering the at least one electrically conductive member.Type: GrantFiled: October 10, 2013Date of Patent: June 6, 2017Assignee: STMICROELECTRONICS PTE LTDInventors: Wee Chin Judy Lim, David Gani, Hk Looi, Bs Aw, Cheng-hai Cheh

Patent number: 9244334Abstract: Described herein are various embodiments of contacts that include different portions angled with respect to one another and methods of manufacturing devices that include such contacts. In some embodiments, a module may include a first portion of a contact that is disposed within a housing and a second portion that is disposed outside of the housing, with the second portion angled with respect to the first portion. Manufacturing such devices may include depositing a conductive material to electrically connect the contact to a contact pad of a substrate. In some embodiments, a deposition process for depositing the conductive material may have a minimum dimension, which defines a minimum dimension of a conductive material once deposited. In some such embodiments, a distance between a terminal end of the contact pin and the contact pad may be greater than the minimum dimension of the deposition process.Type: GrantFiled: March 29, 2013Date of Patent: January 26, 2016Assignee: STMicroelectronics Pte LtdInventors: Hk Looi, Wee Chin Judy Lim, Cheng-Hai Cheh, Bs Aw, David Gani, Tin-Tun Maung, Choon Lee Lai

Patent number: 9003644Abstract: A PNP apparatus may include a robotic arm, and a PNP tool head carried by the robotic arm. The PNP tool head may include a body configured to apply bonding pressure to a first area of an electronic device, and a pick-up tip movable between an extended position and a retracted position relative to the body as the pick-up tip rests against a second area of the electronic device. The pick-up tip may define a vacuum passageway therethrough to couple a vacuum source to the second area of the electronic device.Type: GrantFiled: October 15, 2012Date of Patent: April 14, 2015Assignee: STMicroelectronics Pte LtdInventors: Hk Looi, Cheng-hai Cheh, HaiKin Toh

Publication number: 20140000804Abstract: A pick and place system with an integrated light source to partially cure a light-curable adhesives onto which components have been placed. After a light-curable adhesive in liquid or low viscosity form is applied to a location on a substrate, a pick-and-place head uses a vacuum introduced to its nozzle-like opening to pick a component and place it on to the light-curable adhesive. The pick-and-place head then transmit an appropriate light through the same nozzle-like opening to at least partially cure the adhesive. The component becomes, therefore, at least partially fixed to the substrate and will not shift as the substrate is moved.Type: ApplicationFiled: July 2, 2012Publication date: January 2, 2014Applicant: STMicroelectronics Pte Ltd.Inventors: Han Kong Looi, Cheng-hai Cheh

Publication number: 20120171372Abstract: In automated gluing systems for semiconductor device manufacture, an automatic shutter system is provided for use with an adhesive dispenser that is configured to deposit adhesive for joining elements during final assembly processes. A shutter is configured to interpose itself between a needle tip of the dispenser and a working surface, on which devices in process are positioned, while the dispenser is in a ready position and not actually delivering adhesive, and to withdraw from the interposed position as, or immediately before the needle tip descends to a dispensing position to deposit adhesive on a device. In this way, drops of adhesive that fall from the needle tip while in the ready position are captured by the shutter and prevented from falling onto a device in process in an unintended location of the device.Type: ApplicationFiled: December 30, 2010Publication date: July 5, 2012Applicant: STMICROELECTRONICS PTE LTD.Inventors: Hk Looi, Cheng-hai Cheh
