APPARATUS, METHOD AND COMPUTER PROGRAM PRODUCT FOR DEFECT DETECTION IN WORK PIECES
An apparatus, a method and a computer program product for defect detection in work pieces is disclosed. At least one light source is provided and the light source generates an illumination light of a wavelength range at which the work piece is transparent. A camera images the light from at least one face of the work piece on a detector of the camera by means of a lens. A stage is used for moving the work piece and for imaging the at least one face of the semiconductor device completely with the camera. The computer program product is disposed on a non-transitory, computer readable medium for defect detection in work pieces. A computer is used to execute the various process steps and to control the various means of the apparatus.

A multilayer ceramic capacitor (MLCC) tester includes a power supply source and a station. The station can include at least one test head having a first contact and a second contact arranged and configured to simultaneously electrically connect to a common MLCC transported to a test site, and arc suppression source circuitry. The arc suppression source circuitry can be electrically connected between an output of the power supply source and the first contact, wherein the arc suppression source circuitry is configured to introduce an impedance to the electrical connection between the MLCC and the power supply source.
METHOD AND APPARATUS FOR DETECTING CIRCUIT DEFECTS
The disclosure relates to an RFIC apparatus, and more particularly, to an RFIC circuit having a test circuit, a test apparatus, and a test method thereof. Further, the disclosure relates to a method for estimating or determining a DC gain using a test apparatus and an RF circuit in a DC/AC test stage, and detecting defects of the RF circuit based on the estimated or determined DC gain.
SYSTEMS AND METHODS FOR USE IN HANDLING COMPONENTS
An electrical component testing apparatus can include a vacuum plate including a first surface, a second surface opposite the first surface, and through-holes extending through the vacuum plate from the first surface to the second surface. The apparatus also includes a manifold arranged at the second surface of the vacuum plate. The manifold can include a manifold body and passageways extending within the manifold body, wherein each of the passageways includes a first end and a second end.
