摘要:
A portable electrostatic chuck carrier includes a holder having a dielectric top surface, and bipolar electrodes under the dielectric top surface. The bipolar electrodes includes positive electrodes and negative electrodes electrically insulated from the positive electrodes. The positive electrodes and the negative electrodes are allocated in an alternating pattern in a plane substantially parallel to the dielectric top surface.
摘要:
The present disclosure is directed to an apparatus for the application of soldering flux to a semiconductor workpiece. In some embodiments the apparatus comprises a dipping plate having a reservoir which is adapted to containing different depths of flux material. In some embodiments, the reservoir comprises at least two landing regions having sidewalls which form first and second dipping zones. The disclosed apparatus can allow dipping of the semiconductor workpiece in different depths of soldering flux without the necessity for changing dipping plates.

摘要:
A method includes generating a solvent-containing vapor that contains a solvent. The solvent-containing vapor is conducted to a package assembly to clean the package assembly. The solvent-containing vapor condenses to form a liquid on a surface of the package assembly, and flows off from the surface of the package assembly.
摘要:
A flux dipping apparatus includes a flux plate having a top surface; and a dipping cavity in the flux plate and recessed from the top surface. A flux leveler is disposed over the flux plate and configured to move parallel to the top surface. A piezoelectric actuator is configured to adjust a distance between the flux leveler and the top surface in response to a controlling voltage applied to electrodes of the first piezoelectric actuator.
