Disclosed is a singulation apparatus for cutting a workpiece. The singulation apparatus comprises: i) a processor; ii) at least one chuck device for securing the workpiece to be cut; iii) a cutting device spaced from the at least one chuck device by a separation distance, the cutting device being for cutting the workpiece secured to the at least one chuck device; and iv) an imaging device operable to capture one or more images comprising the cutting device and a reference feature. In particular, the processor is configured to determine a separation distance between the cutting device and the reference feature based on the one or more images as captured by the imaging device, to thereby determine the separation distance between the cutting device and the workpiece as secured to the at least one chuck device.

Singulation apparatus comprising an imaging device

A nozzle device comprising a nozzle chamber includes a fluid inlet located at a first side of the nozzle chamber which is operative to introduce fluid into the nozzle chamber in an injection direction and a fluid outlet at a second side of the nozzle chamber which is operative to expel fluid from the nozzle chamber. A high frequency wave generator is also located in the nozzle chamber which is oriented and operative to generate high frequency waves in a direction which is substantially parallel to the injection direction, whereby to impart high frequency energy to the fluid in the nozzle chamber.

Nozzle device employing high frequency wave energy

A method of configuring a dicing device, which dices along a cutting line of a workpieceaccording to a dicing step, is disclosed. Numerical input of a dicing order of the dicing deviceto dice a workpieceis time-consuming and prone to errors. The disclosed method comprises the step of depicting a graphical user interface, which includes a layoutof the workpiecethat further includes a plurality of cut lines relating to respective cutting lines along the workpiece. The disclosed method further comprises the step of graphically contacting a cut line from the layoutthrough a user-interface device, to allow selection of the cut line before the selected cut line is assigned to the dicing step of the dicing device. By providing the plurality of cut lines in the layoutthat are graphically contactable through the user-interface device, the method advantageously allows an easier process of configuring the dicing step of the dicing device. Also disclosed are a dicing apparatus for dicing a workpiece, as well as a computer-readable medium having a computer program for instructing a computer to perform the disclosed method.

An apparatus for cleaning electronic packages comprises a tank containing cleaning fluid and a holder above the tank that supports the electronic packages above a top surface of the cleaning fluid with the electronic packages facing the cleaning fluid. Acoustic energy generators are immersed in the cleaning fluid for generating and propagating acoustic energy towards the top surface of the cleaning fluid to create streaming fluid jets projecting upwardly at the top surface to contact and clean the electronic packages supported on the holder.
