Abstract: A single-layer redistribution plate functioning as a space translator between a device under testing (“DUT”) and a testing PCB may comprise a hard ceramic plate. A DUT side of the plate may have pads configured to interface with a device under testing. Both sides of the plate may comprise traces, vias, and pads to fan out the DUT pad pattern so that the plate side opposite the DUT side has spatially translated pads configured to interface with the pads on a testing PCB. Fabricating a redistribution plate may comprise calibrating and aligning, laser milling vias, laser milling trenches and pads, copper plating, grinding and polishing, removing residual copper, and coating the copper surfaces.

Abstract: A multilayer printed circuit having a control circuit including n vias that are connected in series between a first and a second electrical terminal so that an applied electric current passes at least partially through each one of the n vias. The control circuit includes track portions in each one of the layers, each one of the n vias connecting a track portion of one layer to a track portion of another layer. The control circuit includes a measurement device for measuring a potential difference across its terminals, storage for storing a threshold value and a comparator for comparing the potential difference with the threshold value so as to validate the printed circuit when the potential difference is lower than the threshold value.

Abstract: The present invention provides a high speed signal fan-out method for BGA and a PCB using the same. The method comprises: providing a printed circuit board (PCB), providing a plurality of vias and signal traces of the vias on the PCB; and providing back-drilled holes for routing of other signal traces at positions corresponding to the vias. The vias are arranged into a plurality of straight lines from an edge to the center of the PCB. The plurality of straight lines each is horizontal or vertical. The signal traces of the vias in a straight line are arranged from high to low or from low to high with respect to routing positions of the vias, and the back-drilled holes of the plurality of vias are arranged in descending or ascending order corresponding to the depths of the back-drilled holes.

Abstract: A printed circuit board (“PCB”) includes a first pattern structure, a second pattern structure, a third pattern structure, and a fourth pattern structure. The first pattern structure includes a first ground pattern. The second pattern structure includes a first line pattern overlapping the first ground pattern and a second ground pattern electrically insulated from the first line pattern. The third pattern structure includes a third ground pattern overlapping the first line pattern and a second line pattern overlapping the second ground pattern. The fourth pattern structure includes a fourth ground pattern overlapping the second line pattern. Therefore, the PCB may decrease noise.

Abstract: A printed circuit board includes a pad to receive an electric signal from a controller, a plurality of signal lines connected to the pad to transmit the electric signal received at the pad, and a signal transmission unit connected to the signal lines to transmit the electric signal to a coil. The plurality of signal lines are configured to face each other in at least a partial region and/or disposed in a zigzag form in at least a partial region. If the printed circuit board and a vibration actuator including the printed circuit board are used, it is possible to change a high frequency interference region according to a pattern by changing a pattern of the printed circuit board, and to improve receiving efficiency of an antenna by reducing high frequency noise.
