PURPOSE:To remove and reinsert a regulating electric component, to easily automatically mount it by a machine and to reduce the number of components by inserting the component into an eyelet having an elastic spring provided in a through-hole of a printed circuit board, and mounting it. CONSTITUTION:An eyelet 31 has a flange 31a at its upper side and an L-shaped protrusion 31b of an elastic spring inside a cylinder. The eyelet 31 having an elastic spring is press-fitted in a through-hole 2 of a printed circuit board 1, an upper retaining caulking jig is brought from upside into contact, after inserting, a lower retaining caulking jig is brought from downside into contact therewith, the eyelet 31 is compressed to be caulked from above and below. Leads 6 of an electric component 5 are inserted to be mounted at the caulked part, and leads 6 are brought into pressure contact therewith by a chevron shape protrusion 31b of the spring of the eyelet 31 and secured. Since the component 5 is mounted by automatically placing by an automatic placing machine 4 without soldering, a cleaning step can be eliminated in manufacture of a PKG. |
