Patent number: 11136202Abstract: Electronic components are transferred from a source surface for supplying electronic components to a destination surface for receiving electronic components by an ejector device that is locatable at an ejection position for pushing an electronic component mounted on the source surface towards the destination surface. A support device that is locatable at a receiving position supports the electronic component that is pushed onto the destination surface. Further, a pre-transfer imaging device inspects the electronic component before it is transferred from the source surface and a post-transfer imaging device inspects the electronic component after it has been transferred onto the destination surface, wherein the pre-transfer and post-transfer imaging devices are located on opposite sides of the source and destination surfaces.Type: GrantFiled: January 6, 2020Date of Patent: October 5, 2021Assignee: ASM TECHNOLOGY SINGAPORE PTE LTDInventors: Kui Kam Lam, Kai Siu Lam, Yen Hsi Tang, Hung Kit Chan, Ka Yee Mak
