Publication number: 20230226644Abstract: The present invention discloses a laser scribing device that produces optimal scribing lines within a target substrate based on its thickness. This is accomplished by generating multiple or an optimum number of focal points, and dynamically adjusting the focal lengths of the focal points to create optimal distances between the scribing lines. The resulting scribing lines are efficient in breaking the target substrate. The position of the focal points and the distance between them are determined based on the thickness of the target substrate, and the distance between focal points or scribing lines can be dynamically adjusted by modifying the focal lengths of the focal points.Type: ApplicationFiled: March 19, 2023Publication date: July 20, 2023Inventors: Beng So RYU, Hark Yong KIM, Gwan Yoo KIM, Dong Woo SHIN, Seong Ho SONG, Jang Hyun KIM

Patent number: 11166351Abstract: In a method of manufacturing an electronic device, a solder paste is coated on a substrate pad of a substrate. An electronic product is disposed on the substrate such that a solder on an input/output pad of the electronic product makes contact with the solder paste. A first microwave is generated toward the solder paste during a reflow stage to heat the solder paste. A phase of the first microwave is changed during the reflow stage. Heating of the solder paste causes the solder to reflow, thereby forming a solder bump between the substrate pad and the input/output pad.Type: GrantFiled: September 21, 2018Date of Patent: November 2, 2021Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Sin-Yeob Lee, Dong-Woo Shin, Hyun-Seok Choi
