    Abstract: A printed circuit board apparatus comprises a printed circuit board. The printed circuit board includes a first and a second surface and a hole portion. A printed pattern is formed on the first surface, and a parts having a lead is mounted on the second surface. The printed circuit board apparatus also includes an eyelet and plural solder entering portions. The eyelet includes a curling portion and a head portion positioned on the first and second surfaces of the printed circuit board, respectively, and a cylindrical portion, connecting the head and curling portion, inserted into the hole of the printed circuit board. A plurality of solder entering portions are formed at equal intervals on the curling portion. From the solder entering portions, solder enters into space between the curling portion and the first surface face of the printed pattern surrounding the hole of the printed circuit board and the eyelet.

    Abstract: Liners are inserted into holes in printed circuit boards by means of a templet having holes therein at locations corresponding to the holes in the printed circuit board. An excess of liners are placed on top of the templet and the templet is vibrated until one liner enters each hole in the templet. Thereafter, the templet is placed on top of the printed circuit board and the individual liners are punched from the templet holes into the printed circuit board holes.

    Abstract: A hole liner includes a metal body insertable into a hole in a printed circuit board for holding a component lead to be soldered to the board. An upper stop limits insertion, while a resilient latch near the lower end of the body engages the lower surface of the board to prevent withdrawal of the liner. The lower end of the body includes jaws for gripping a component lead inserted into the liner, and at least one of the jaws is connected to the resilient latch. The outer surfaces of the jaws are angled inwardly to aid insertion of the body into the hole, and upon insertion the jaws contract and the latch is resiliently forced inwardly. Upon full insertion the latch moves to its latching position in engagement with the undersurface of the board. The mouth or gap defined by the jaws is smaller than the component lead, so that when the lead is inserted the latch is further extended, thus firmly holding the liner in place on the board.
