| Research Abstract |
The microwave heating system using evanescent wave for soldering fine circuits had been proposed. The evanescent wave is useful for the microwave heating very locally. The heating system consists of a matching circuit and a resonator for enhancing the magnetic field around the mouth of a circular waveguide in which the strong evanescent waves are excited. The experiments of heating lead-free solders have been done with the microwave at a frequency of 2.3-2.35GHz and a power of about 200W. The lead-free solder can be heated locally to be melted with microwave without any breakdown in the resonator.
