PURPOSE:To contrive the simplification of a component mounting work or the like and a shortening of a working time by a method wherein a multitude of holding bodies, which press and hold the component mounting part of a circuit board positioned at a position of a prescribed height, are constituted of holding bodies having wire materials which can be buckled. CONSTITUTION:A circuit board 17 mounted with electronic components 23 is pressed by a first back-up brush 13 and a second back-up brush 18. At this time, the board 17 is pushed up by thin wires 16, which make contact to a component mounting part A of the board 1 7, of the brush 13 and thin wires 20, which make contact to the mounting part A, of the brush 18 and these thin wires 16 and 20 are buckled by this concentrated load. In this case, thin wires other than the buckled thin wires 16 and 20 are in a state that they are erected and the load in every thin wire of these erected thin wires 16 and 20 is small. Accordingly, the board 17 can be held by component mounting surfaces 17a and 17b in a state that the surfaces 17a and 17b are parallel to a plate surface 11a. |
