ABSTRACT:
A component mounting method recognizes reference marks on a printed circuit board and an electronic component, and uses these reference marks to determine a shift between a position of the circuit board and a position of the electronic component. This shift is corrected and then the electronic component is mounted to the printed circuit board such that electrical connecting portions of the circuit board are connected to electrical connecting portions of the electronic component. The reference marks are formed simultaneously with corresponding electrical connecting portions via a mask, such that in order to accurately position the electrical connecting portions, it is only necessary to accurately relatively position the reference marks.
