Title:
METHOD OF MANUFACTURING MAGNETIC SENSOR AND LEAD FRAME
Document Type and Number:
Japanese Patent JP3823953
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a magnetic sensor manufacturing method that realizes correct measurement of three-dimensional orientation of an external magnetic field and reduction in manufacturing costs.
SOLUTION: The magnetic sensor manufacturing method comprises steps of: preparing a lead frame 10 having at least two stage units 6, 7, a frame unit 9 provided with lead frames 4, 12-14 which are placed around the stage unit 6, 7, and coupling units 12, 13 for coupling these; plastically deforming the coupling units 12, 13 to slant the stage units 6, 7; pressing the stage units 6, 7 while the frame unit 9 is fixed for elastically deforming the coupling units 12, 13; adhering magnetic sensor chips 2, 3 to the stage units 6, 7 while arranging the stage units 6, 7 and a frame unit 9 substantially on the same plane; wiring the magnetic sensor chips 2, 3 to the lead 4; and releasing the stage units 6, 7 to allow the coupling units 12, 13 to recover from the elastic deformation.
