METHOD FOR FABRICATING MAGNETIC FIELD SENSOR BY USING MULTILAYER PCB MANUFACTURING PROCESS AND MAGNETIC FIELD SENSOR FABRICATED USING THE SAME METHOD

摘要

PURPOSE: A method for fabricating a magnetic field sensor by using a multilayer PCB manufacturing process and a magnetic field sensor fabricated using the same are provided to easily manufacture the high sensitivity with a low cost. CONSTITUTION: According to the method, a diameter of a pair of holes(18,19) is equal or smaller than that of the drill is formed on the magnetic pattern(12) before the process of penetrating the throughhole so as to easily form the throughhole to apply the electric current between the layers when the magnetic sensor(10) is manufactured by using the multilayer PCB manufacturing process and the magnetic pattern(12).
