| titleOfInvention | Pressure sensor chip with laser adjustment and repair function |
| abstract | The utility model relates to the technical field of laser adjustment and repair of ceramic pressure sensors, in particular to a pressure sensor chip with a laser adjustment and repair function, which comprises: including the chip body, and the shaping in the location portion of chip body week side still includes: the laser adjusting circuit comprises force sensitive resistors which are symmetrically arranged on the chip body and connected into a Wheatstone bridge, and a plurality of adjusting resistors which are arranged on the chip body and arranged at the upper end of the force sensitive resistors, wherein the adjusting resistors form a laser adjusting circuit with a coarse/fine adjusting function. The laser resistance trimming circuit has the functions of coarse trimming and fine trimming, can greatly improve the resistance trimming precision of products, reduce the temperature drift of resistors, improve the temperature stability of the products, does not influence the bridge circuit power after laser resistance trimming, greatly improves the maximum withstand voltage and the maximum power of the sensor, and can meet the requirements of harsh use environments. |
