The present invention includes a system and method for three-dimensional imaging and analysis of electronic components. Specifically, it permits rapid and reliable inspection of the lead foot angle in integrated circuit packages. A first image capturing device, a second image capturing device and a third image capturing device are arranged in a 'corner shape' or 'L-shape.' The first image capturing device forms the corner and obtains an image of the bottom of the component. The perspective viewing angle of the second image capturing device and the perspective viewing angle of the third image capturing device are orthogonal to each other to allow accurate three-dimensional reconstruction of the lead angles and detection of flaws or bends.

The present invention includes a transfer system for flipping and checking electronic devices. A first rotary device has a plurality of transfer heads configured to pick electronic devices from a wafer table and place the electronic devices on a transfer head of a second rotary device. Check stations can be positioned around the first and second rotary devices and configured to inspect or check the electronic devices during the flipping process. The transfer system can further include an imaging device to inspect the accuracy of picking and placing of the electronic devices during the flipping process. The wafer table and the first rotary device are inclined to increase the operation space. The system accurately picks, flips and transfers chips at a high operation speed.

A method for laser scribing of thin-films for the manufacture of solar cell panels comprises loading a workpiece with the transparent substrate facing downwards in an input station of a first machine; biasing a reference edge of the workpiece against a front and rear stopper associated with a linear drive; translating the workpiece back and forth between the input station and output station and firing two or more laser beams at a first frequency substantially vertically through a space between the input and output stations to pass through the transparent substrate of the workpiece to scribe parallel lines on the front electrodes with reference to the edge of the workpiece in contact with the front and rear stoppers; and indexing the two or more laser sources and repeating the back and forth translation of the work piece between the input and output stations.

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.
