Abstract:
1. An electronic component mounting method for mounting the electronic component on a substrate by soldering a connection terminal disposed at both ends of a main body of the electronic component to a pair of electrodes provided on the substrate, comprising an adhesive supplying step of supplying a thermosetting adhesive mixing solder particles to the substrate, a component mounting step of mounting the electronic component on the substrate after the adhesive supplying step, and a heating step of heating the substrate after the component mounting step, wherein the adhesive supplying step is characterized by supplying the adhesive to the electrode, and also supplying the adhesive to an adhesion reinforcing portion determined between the pair of electrodes on the substrate, the component mounting step is characterized by fitting the connection terminal to the adhesive supplied on the electrode, and also fitting the main body to the adhesive supplied in the adhesion reinforcing portion causing a portion of a surface of the main body to contact the adhesive, and the heating step is characterized by forming a solder junction by bonding the connection terminal and electrode by fusing the solder particles in the adhesive supplied to the electrode, and also forming an adhesion reinforced part for fixing the main body to the substrate by heating and curing the adhesive by sealing the inside of the adhesive with solder part by fusing and solidifying of solder particles contained in the adhesive supplied in the adhesion reinforcing portion causing the adhesive to spread and contact a larger portion of the surface of the main body, wherein the adhesion reinforcing portion is formed on the surface of the substrate, extends continuously between and partly overlaps the pair of electrodes to prevent short circuiting of the pair of electrodes, and a portion of the adhesive other than the adhesive supplied to the electrodes is set on a concave resist film of the adhesion reinforcing portion, and the solder part is held in the concave portion.
