Patent number: 9929036Abstract: A system and method for peeling a semiconductor chip from a tape using a multistage ejector is disclosed. A housing in the multistage ejector houses a plural sets of tape removing contacts. A pick and place unit is moved slowly to have contact with the chip. A vacuum source is utilized for generating vacuum to suck the tape. Plural sets of contacts such as inner, middle and outer contacts are independently or together moved below the tape at various stages by utilizing their respective actuation mechanism. A controller can independently control the movements of each contact to effectively remove or loosen the tape from the chip. A pick and place unit can then pick up the chip easily without any damage to chip.Type: GrantFiled: May 13, 2015Date of Patent: March 27, 2018Assignee: MANUFACTURING INTEGRATION TECHNOLOGY LTDInventors: Kim Mone Kwong, Kok Yeow Lim, Zhiqiang Mao

Patent number: 8864121Abstract: The present invention describes an adaptive clamp width adjusting device (200) for use in an integrated circuit package process machine. The device (200) includes a travel component (210) and a fixed component (310). The travel component (210) carries a clamp (220a,220b) with an adjustable width and a rotary screw (230a) operable for such adjustment by a driven wheel (232). The fixed component (310), mounted on a base plate (312), includes a motor (320) and a drive wheel (324) attached to the motor shaft. When the device (200) is in a clamp width conversion station (40a), the travel component (210) is aligned above the fixed component (310) so that when the base plate (312) is raised and the drive wheel (324) engages the driven wheel (232), the clamp width is operable to be adjusted by the motor (320) according to a width of a workpiece (W).Type: GrantFiled: June 18, 2009Date of Patent: October 21, 2014Assignee: Manufacturing Integration Technology LtdInventors: Xiang Bao Zhang, Siew Hua Ng, Teck Keong Boh, Kim Mone Kwong

Patent number: 8727693Abstract: The present invention provides apparatuses for processing an object just as semiconductor chips and dies. The first embodiment comprises two or more pick and place heads (FIG. 1) which operate sequentially (ie leap frog) to pick components from a first location to a second. The second embodiment (FIG. 8) comprises a flipping head combined with a pick and place heads where an object is picked up by the flipping head, turned over and then presented to a pick and place head for relocation to an output.Type: GrantFiled: May 6, 2008Date of Patent: May 20, 2014Assignee: Manufacturing Integration Technology LtdInventors: Francis Medel P. Tundag, Han Yong Lam, Kam Yee Fong

Publication number: 20120181259Abstract: The present invention describes an apparatus (100) for a first laser scribing (P1) on the front electrode of a thin film solar cell panel and a similar apparatus (100a) for subsequent laser scribing (P2, P3) on the semiconductor layer and semiconductor layer/rear electrode. Before starting scribing process P1, the left hand edge or reference line on the left hand edge on a workpiece is aligned substantively parallel to the linear drive (140) before translating the workpiece on the apparatus (100). Similarly, the first and second scribed lines (Lp1, Lp2) formed during the P1 and P2 processes are separately aligned parallel to the linear drive (140) before starting the relevant process (P2, P3). Alternatively, parallelism of the workpiece is carried out for each batch of the workpiece. In both apparatuses (100, 100a), the laser sources (150) are mounted on independently motorized axes.Type: ApplicationFiled: October 7, 2009Publication date: July 19, 2012Applicant: Manufacturing Integration Technology Ltd.Inventors: Kim Mone Kwong, Teck Keong Boh, Kok Yeow Lim, Han Yong Lam
