Patent number: 11943877Abstract: A circuit board structure includes a circuit substrate having opposing first and second sides, a redistribution structure disposed at the first side, and a dielectric structure disposed at the second side. The circuit substrate includes a first circuit layer disposed at the first side and a second circuit layer disposed at the second side. The redistribution structure is electrically coupled to the circuit substrate and includes a first leveling dielectric layer covering the first circuit layer, a first thin-film dielectric layer disposed on the first leveling dielectric layer and having a material different from the first leveling dielectric layer, and a first redistributive layer disposed on the first thin-film dielectric layer and penetrating through the first thin-film dielectric layer and the first leveling dielectric layer to be in contact with the first circuit layer. The dielectric structure includes a second leveling dielectric layer disposed below the second circuit layer.Type: GrantFiled: March 2, 2022Date of Patent: March 26, 2024Assignee: Unimicron Technology Corp.Inventors: Wen-Yu Lin, Kai-Ming Yang, Chen-Hao Lin, Pu-Ju Lin, Cheng-Ta Ko, Chin-Sheng Wang, Guang-Hwa Ma, Tzyy-Jang Tseng

Patent number: 8833759Abstract: A printer includes an enclosure, a paper output tray, and two positioning devices. The enclosure includes a receiving base and two side portions extending from the receiving base. The paper output tray is pivotally mounted between the two side portions. The two positioning devices are mounted to the two side portions. The paper output tray is placed in the receiving base in a first position. The paper output tray can rotate to resist each of the two positioning devices and move to a side portion, thereby enabling the paper output tray to rotate to a second position. Each of the two positioning devices restores to an original position to support the paper output tray stably in the second position, to enable the removal of a paper jam or other circumstance.Type: GrantFiled: April 15, 2013Date of Patent: September 16, 2014Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Kai Fan Chiang, Shu-Kai Lu, Chin-Ta Ma
