Abstract: PURPOSE:To avoid defective soldering caused by the adhesion of adhesive to an electrode by a method wherein uncured thermosetting resin composition is applied to the component mounting part on a circuit board and heated to soften and, after an electronic component is mounted, cured by heat. CONSTITUTION:After a resist layer is formed on the surfaces of a circuit board 2 and an electrode 4, an adhesive layer 1 is formed on the circuit board 2. The adhesive is mainly composed of epoxy resin having epoxy functional groups or acrylate resin having acryloil groups.

When the temperature of the adhesive layer 1 exceeds the softening point of the adhesive, an electronic component is mounted. The circuit board 2 is again heated by the curing apparatus or a reflow apparatus and the adhesive is completely cured to obtain an adhesion strength required in a next soldering process. With this constitution, adhesive coating using a barrel is not necessary and defective soldering caused by stringy adhesive can be avoided.
