Magnet placement is described for integrated circuit packages. In one example, a terminal is applied to a magnet. The magnet is then placed on a top layer of a substrate with solder between the terminal and the top layer, and the solder is reflowed to attach the magnet to the substrate.

Disclosed is an integrated acceleration, speed and vibration sensor. The sensor includes a housing, a base, a sensing and signal processing circuit, a current loop circuit, an anti-surge PTC and an aviation plug. The housing is mounted on the base. The sensing and signal processing circuit and the current loop circuit are used to fabricate a PCB circuit board, and then the PCB circuit board is mounted in the housing. A power supply and signal line is connected to the aviation plug. An M6 threaded hole is formed in a bottom of the housing of the sensor and is used to connect with an object to be detected. A power supply is negatively connected to one end of a varistor and the other end of the varistor is connected to the housing as the anti-surge PTC to play a protective role. The M6 threaded hole formed in the bottom of the housing of the sensor is used to connect with the object to be detected and improve the stability. At the same time, after the PCB circuit board is mounted, adhesive filling is performed to improve the vibration resistance.

In a multi-axial angular velocity sensor, a substrate part perpendicular to a D3 axis includes a pair of long sides parallel to a D2 axis and a pair of short sides parallel to a D1 axis. Three sensor elements for the three axes are mounted on an upper surface of the substrate part. A piezoelectric body of each of the sensor elements comprises a plurality of arms. Theses arms extend in a predetermined direction of extension in a plane perspective of the upper surface. The piezoelectric body has the direction of extension as its long direction. Two of the three sensor element are arranged side by side in a direction along the short sides of the substrate part with orientations so that the directions of extension become parallel to the long sides. A remaining one is arranged in a direction along the long sides relative to the two elements with an orientation so that the direction of extension becomes parallel to the short sides.
