Efficiency of the induction heating systems of the ring type and on the unclosed magnetic circuit, applied to soldering details and electronic components, is sized up at assembling electronic modules. For inductors on the magnetic circuit, at the expense of the concentration of an electromagnetic field in a working gap, the efficiency of details heating raises and the heating zone is localized. Modeling of the parameters of both the electric and magnetic fields in COMSOL gives temperature profiles of heating of the surface-mounted components over a frequency range of 22 – 100 kHz. The highest speed of heating at a level of 12–15°С/sec is attained at lower frequencies where the penetration of the electromagnetic field is deeper.
