Systems and methods for monitoring power in a conductor. A flex circuit may include multiple layers including a voltage sensing layer, a coil layer, and a ground layer. The coil layer includes traces that form a coil structure around a conductor when the flex circuit is wrapped around the conductor. The coil layer generates a voltage that may be integrated to determine a current in the conductor. When the flex circuit is wrapped around the conductor, the voltage sensing layer is closest to the conductor. The voltage sensing layer forms a capacitor with the conductor. Using an adjustable capacitive voltage divider, the voltage of the conductor may be determined from a voltage signal received from the voltage sensing layer.

A device comprising a single-sided printed circuit board (PCB) having a non-metallized hole, and a connection area (CA) close to the non-metallized hole on a metallized side of the single-sided printed circuit board. The present invention provides a conducting bridge (CP) from the connection area (CA) and at least partially covering the non-metallized hole, for allowing the connection area (CA) to be contacted, e.g. by a probe (P), from a non-metallized side of the single-sided printed circuit board (PCB) through the non-metallized hole.

The invention relates to a method for producing an electronic circuit (19) in a production system (23) (for example, a soldering furnace comprising a wave soldering system (32)). The invention also relates to an assembly comprising a circuit carrier (13) and an electronic circuit (19). Lastly, the invention relates to a production system (23) for producing an electronic circuit (19) on a circuit carrier (13). According to the invention, a measurement module (14) is used on the circuit carrier, which is already functional during the performed process step and can send measurement data to an external controller (25), for example. Said measurement module can be removed again after performance of the process step or after completion of the circuit carrier (13). Therefore the circuit carrier can advantageously be cost effectively produced, even if the measurement procedure carried out in the measurement module (14) is performed using high-value components. Since the measurement module (14) can be reused, the costs of the components of the measurement module places only a slight burden on the unit costs of the circuit carriers to be produced.

A printed circuit board includes a body and a belly pad seated within with the body. The belly pad (108) is electrically separated into a first pad (110) and a second pad (112). The first pad and the second pad are arranged to be electrically connected to one another by an interconnect (106) electrically connecting the belly pad to a conductive plane (126) of an electrical component, thereby allowing continuity testing across an interface between the first pad and the interconnect.

摘要:
A method and apparatus for adjusting circuit operation in response to physical orientation of an integrated circuit (IC) coupled to a host site via direct soldering or a socket. The IC can be installed in a correct orientation or rotated and installed in an incorrect orientation. The IC may have a square, substantially symmetric footprint and the incorrect orientation may correspond to 90 or 180 degree rotation of the IC from the correct orientation. The orientations may be discerned by sensing electrical characteristics of the installed IC. For example, the IC may ground a detection line when installed in the correct orientation, while the detection line may be floating when the IC is installed in an incorrect orientation. The IC may be switchably connected to other components such as a power supply only when it is detected as being installed in the correct orientation.
