Abstract:
The invention relates to a method for producing a circuit board (1) involving the removal of a subregion (6) thereof. In said method, at least two layers or plies (2, 3, 4, 5) of the circuit board (1) are interconnected, the subregion (6) to be removed is prevented from being connected to an adjacent ply (4) of the circuit board (1) by providing or applying an adhesion-preventing material (7), and peripheral zones (8) of the subregion (6) to be removed are separated from adjoining zones of the circuit board (1). According to the invention, once the peripheral zones (8) have been separated or entirely cut off, an outer surface (9) of the subregion (6) to be removed is coupled or connected to an external element (11), and the subregion (6) to be removed is separated from the adjacent ply (4) of the circuit board (1) by lifting or displacing the external element (11), thus making it possible to remove a subregion (6) to be removed from a circuit board (1) in an easy and reliable, and if necessary automated, manner. Also disclosed is a use of such a method for producing a multilayer circuit board (1) and especially for creating voids (14) in such a circuit board (1).

A method of fabricating a semiconductor plastic package can include: providing a core board, which includes at least one pad, and which has a coefficient of thermal expansion of 9 ppm/° C. or lower; stacking a build-up insulation layer over the core board; forming an opening by removing a portion of the build-up insulation layer such that the pad is exposed to the exterior; and placing a semiconductor chip in the opening and electrically connecting the semiconductor chip with the pad. This method can be utilized to provide higher reliability in the connection between the semiconductor chip and the circuit board.
Abstract:
A breakaway RFID tag is configured such that it includes part of a Printed Circuit Board Assembly (PCB). Thus, the breakaway RFID tag can be used to track the PCB as it migrates through a manufacturing process. In one embodiment, the RFID tag can be assembled first and then used to track the PCB as it is populated with components and installed into larger assemblies and ultimately into the end device. Once the PCB is installed into a larger assembly or the end device, the breakaway RFID tag is configured such that it can be broken off and attached to the outside of the larger assembly or end device.
