Abstract: In a method of manufacturing an electronic device, a solder paste is coated on a substrate pad of a substrate. An electronic product is disposed on the substrate such that a solder on an input/output pad of the electronic product makes contact with the solder paste. A first microwave is generated toward the solder paste during a reflow stage to heat the solder paste. A phase of the first microwave is changed during the reflow stage. Heating of the solder paste causes the solder to reflow, thereby forming a solder bump between the substrate pad and the input/output pad.
