SIMULATION-BASED IMPLEMENTATION OF MAGNETIC FIELD ORIENTATION FOR ACCURATE INDUCTION

Chidozie N. Okpala, S. M. Lawan

Abstract


The traditional methods for printed circuit boards (PCB) diagnoses is still incapable of achieving the desired speed and accuracy. These methods require a direct connection to PCB traces and pads to perform the checkups, which takes a lot of time maybe up to hours or days to discover the fault. In this paper, a new design for a mini coil which induces electric current in a narrow copper trace inside the PCB is presented. The new mini coil features the ability to stimulate electromotive force in a narrow path (0.8-1.2) mm avoiding any considerable effect on the surrounding copper traces. The design of the new mini coil was carried out by Finite Element Method Magnetics simulation software. This paper shows the magnitude of flux density β along a parallel PCB. The design of this mini coil represents the first part of a whole model design for PCB diagnosis.
