Abstract
Terminals of a plurality of types of components to be mounted on a circuit board are provided beforehand with a joining material corresponding to the type of component. A basic joining material is applied to the circuit board all at one time. The basic joining material is commonly usable for joining all of the types of components to the circuit board. An individual joining material is applied to certain locations on the circuit board, to which locations components of a particular type are to be mounted. The individual joining material matches properties of the joining material provided beforehand to the components of the particular type. The second step may be performed before the first step to yield the same results.
Claims6
A method of manufacturing a circuit board to be mounted with a plurality of types of components each having a plurality of terminals which are precoded with a joining material corresponding to one of said types of components, comprising:
- a first step of applying a basic joining material to said circuit board all at one time;
- and
- a second step of applying an individual joining material whose properties match that of said joining material to a plurality of locations of said circuit board where components of a particular type are to be mounted thereon.
