Magnetic sensor with components attached to transparent plate for laser trimming during calibration
A magnetic sensor is provided with a permanent magnet structure, a magnetically sensitive component and a transparent plate through which the magnetically sensitive component can be selectively trimmed by a laser beam through the transparent plate. The magnetically sensitive component is attached to...

| description | A magnetic sensor is provided with a permanent magnet structure, a magnetically sensitive component and a transparent plate through which the magnetically sensitive component can be selectively trimmed by a laser beam through the transparent plate. The magnetically sensitive component is attached to an under surface of the plate which is provided with conductive runs, conductive circuit points and conductive pads. The magnetically sensitive component is provided with solder bumps that are soldered to the conductive circuit points on the under surface of the transparent plate. The magnetically sensitive component is rigidly attached to the permanent magnet structure by an epoxy or other suitable material. This disposes the magnetically sensitive component between the transparent plate and the permanent magnet structure. The magnetically sensitive component can be calibrated by laser trimming resistors on an integrated chip through the transparent plate. |
