Abstract:
A rigid-flex PCB includes an array of rigid PCB "islands" interconnected by a flexible PCB formed into flexible connectors. The conductive and insulating layers of the flexible PCB extend into the rigid PCBs, giving the electrical connections to the rigid PCBs added resistance to breakage as the rigid-flex PCB is repeatedly stressed by bending and twisting forces. In addition, the durability of the rigid-flex PCB is enhanced by making the power and signal lines driving the rigid PCBs redundant so that a breakage of a line will not necessarily affect the operation of the rigid PC B to which it is attached. The rigid-flex PCB is particularly applicable to light, pads used in phototherapy, wherein LEDs mounted on the rigid-PCBs are powered and controlled through the redundant lines in the flexible PCB.
Abstract:
Die Erfindung betrifft eine elektronische Komponente (E), umfassend einen Trägerkörper (1) mit wenigstens einem elektrischen Anschluss (2) und einer Leiterplatte (3) mit einer elektrischen Schaltungsanordnung, wobei - der wenigstens eine elektrische Anschluss (2) durch die Leiterplatte (3) hindurch geführt ist und - der wenigstens eine elektrische Anschluss (2) auf einer Oberseite der Leiterplatte (3) mit der elektrischen Schaltungsanordnung elektrisch leitend verbunden ist. Erfindungsgemäß ist mindestens ein temperaturstabiles Zwischenelement (5)vorgesehen, welches zwischen dem Trägerkörper (1) und der Leiterplatte (3) angeordnet ist. Die Erfindung betrifft ferner ein Verfahren zur Montage einer elektronischen Komponente (E).
Abstract:
The invention relates to a conductor assembly comprising a resilient tubular outer casing (1) with a flexible printed circuit board (6) in the outer casing's interior. On the circuit board a sensor (3) is arranged. A cavity (8a-c) in the outer casing adjacent to the sensor is filled with a rigid filling material (9). Where the rigid filling material extends in the lengthwise direction of the tubular outer casing (1) at least from one side of the sensor to the opposite side of the sensor. This means that the sensor will not be affected when the conductor assembly is bent or otherwise affected mechanically. The conductor assembly's outer casing (1) comprises an opening (7a-c) to a cavity (8a-c) in the outer casing in connection to the sensor, through which a filling material can be supplied in liquid form. Typically the conductor assembly includes two cavities (8a-b) in the outer casing on the side of the flexible circuit board (6) where the sensor is mounted, the two cavities being on either side of the sensor, and a third cavity (8c) in the outer casing on the side of the flexible circuit board (6) which is opposite to the sensor. In an advantageous embodiment the extension of at least one cavity (8a-c) in the outer casing is limited by bumps (4a-f) on either side of the cavity thus defining the cavity. Injected filler material propagation is governed by these bumps to the relevant space. Typically, the conductor assembly is a catheter or part of a catheter.
Abstract:
Provided is a drive unit for an auto-injector having a drive unit housing arranged for docking receipt of a syringe or of a cassette unit comprising a syringe movable from a rest position, in which a needle tip of the syringe is within the drive unit housing to a use position, in which the needle tip protrudes from a needle delivery aperture; and a drive arrangement including one or more electrically powered sources of axial drive; a first drive transfer element for advancing the syringe to said use position; and a second drive transfer element for moving a plunger into the barrel of the syringe to eject liquid contents thereof. The drive unit housing is provided with a skin sensor arrangement having an array of plural skin sensor electrodes located about the needle delivery aperture.
