Plurality of arrangements each including an ic magnetic field sensor and two ferromagnetic field concentrators, and a procedure for incorporating each arrangement into a package

摘要: In an embodiment of the invention, a magnetic sensor comprises IC flux and two concentrators (18,19) which are each section ferromagnetic lead frame. A (18b) first concentrator (18), semiconductor chip (4) (19b) second create sub-unit (18b;4;19b) having three sandwich like layers (I,II,III). further (18a) (18) is sheet metal object shape single staircase-like step. The step exhibits surface (22) (23) parallel thereto. One side disposed on top in layer (I). Second (II). (17) non-ferromagnetic frame mounting (19) third (III). configuration can without difficulty be assembled packaged conventional assembly line, whereby expensive alignment operations during occurrence relatively large inaccurate air-gaps avoided.
