Surface-mountable magnetic field sensor having a semiconductor chip and method for producing a circuit board having a magnetic field sensor

摘要

A surface-mountable magnetic field sensor (1) with a semiconductor chip (4), a magnetic field measuring device (30), and in a method for producing and populating a circuit board (24) having a magnetic field sensor (1), the magnetic field sensor (1) has a semiconductor chip (4), which is arranged on a flat-conductor substrate (5). At least three flat-conductor electrodes (6 to 9), which protrude out of a plastic housing side (10), are electrically connected to the semiconductor chip (4). The flat-conductor substrate (5) and the semiconductor chip (4) are embedded in a plastic housing (11). The plastic housing (11) can be inserted with the embedded semiconductor chip (4) into a magnetic field gap (12), with the flat-conductor electrodes (6 to 9) protruding, wherein the flat-conductor electrodes (6 to 9) have bends (13 to 16) at a distance from the plastic housing side (10), the bends being surface-mountable on a circuit board.
