Patent number: 11973054Abstract: A method for transferring an electronic device includes steps as follows. A flexible carrier is provided and has a surface with a plurality of electronic devices disposed thereon. A target substrate is provided corresponding to the surface of the flexible carrier. A pin is provided, and a pin end thereof presses on another surface of the flexible carrier without the electronic devices disposed thereon, so that the flexible carrier is deformed, causing at least one of the electronic devices to move toward the target substrate and to be in contact with the target substrate. A beam is provided to transmit at least a portion of the pin and emitted from the pin end to melt a solder. The electronic device is fixed on the target substrate by soldering. The pin is moved to restore the flexible carrier to its original shape, allowing the electronic device fixed by soldering to separate from the carrier.Type: GrantFiled: January 18, 2022Date of Patent: April 30, 2024Assignee: Stroke Precision Advanced Engineering Co., Ltd.Inventors: Yu-Min Huang, Sheng Che Huang, Chingju Lin, Wei-Hao Wang

Patent number: 10324262Abstract: An assembly for splicing first and second optical fibers is contemplated. The assembly typically comprises a splicing member disposed within a barrel member. A first optical fiber can be inserted through a first end of the barrel member, and a second optical fiber can be inserted through a second end of the barrel member to splice ends of the first and second optical fibers in the splicing member. A recess at the second end of the barrel can be used to lock the second optical cable, and a clamping member can be used to hold the second optical fiber. An optical fiber stub holder can couple the first end of the barrel member and an optical fiber stub from which the first optical fiber extends. Thus, the first and second optical fibers can be effectively secured in a splicing relationship using the assembly.Type: GrantFiled: December 7, 2017Date of Patent: June 18, 2019Inventor: Wei Min Wang

Patent number: 7883275Abstract: A three rod bundle confined inside a sleeve is constructed as a light guiding fiber mechanical splicing device which is stiff, strong and precise, with no moving parts. The design also applies to splicing fibers to pre-polished optical connectors through a built-in model of this innovative mechanical splicer. Applying the Soddy circles formula and using a bin approach assists in deriving the exact rod sizes needed and sleeve bore size to accommodate the three-rod bundle, so that this apparatus can be properly designed to guide any size of light guide fibers and studs with minimum clearance. Rods of varying diameters are sorted into bins and chosen based upon the aperture desired, thus eliminating the need for tight tolerance of the diameters of the three rods. This unique design allows for construction of a precision virtual hole of very long depth, which enables two optical fiber studs to butt against each other with a core to core misalignment of less than 1 um for single mode fiber optics cables.Type: GrantFiled: May 27, 2009Date of Patent: February 8, 2011Inventor: Wei-Min Wang

Patent number: 6878040Abstract: This invention pertains to methods and apparatus for polishing and planarization of workpieces, such as fiber optics connectors, metallographic samples, semiconductor wafers, microelectronic substrate, optical devices and the like. The polishing pattern is a hypotrochoid generated by a spur gear rotating inside of an internal gear. The hypotrochoid is a superior polishing pattern because it not only provides a pattern similar to a figure eight pattern for producing optimal polishing conditions, but it also appears to precess around the center of the polishing space and maximize the utilization of the polishing pad or film.Type: GrantFiled: August 30, 2002Date of Patent: April 12, 2005Inventor: Wei-Min Wang
