A conventional circuit board with outer leads is a printed wiring board 1 on which a required circuit pattern is formed, as shown in Figure 3.
It is constructed by mounting an electronic component 12 and a semiconductor chip 13 on the board 1 by soldering or wire bonding, and by soldering an outer lead 14 for connection to a motherboard. Although not shown, the component mounting portion of this circuit board is sealed with resin, metal, ceramic, or the like.

Printed wiring boards include glass epoxy copper-clad laminates with circuit patterns formed by etching or plating, and ceramic sheets printed with conductive paste, insulating paste, resistive paste, etc., and subjected to laser IJ printing. Ceramic circuit boards, etc., are used. Furthermore, there are various sealing methods depending on the purpose, such as sealing the entire body with resin using methods such as transfer molding or potting, and hermetically sealing the body by storing it in a metal case.

However, whichever method is used, outer leads 14 must be attached to the printed wiring board for connection to the motherboard. This outer lead is generally made by punching or etching a metal plate (copper plate, nickel-iron alloy plate, etc.) with a thickness of 0.2 to 0.8 mm.
It is formed by making a continuous body 15 as shown in 4, soldering it to the printed wiring board 11, and then cutting off the continuous part.

Therefore, the outer lead is a continuum 15 as shown in Figure 4.
It must have enough rigidity to maintain its shape in this state, and its dimensions cannot be made too small. This prevents miniaturization of the pitch P of the outer leads 14 coming out from the printed wiring board 11, and as a result,
This increases the area occupied by this circuit board on the motherboard, which hinders the increase in density of the composite circuit board, the increase in the number of bins of the functional circuit module, and the increase in the number of functions.

The present invention provides a circuit board with outer leads that solves the problems of the prior art as described above, and the structure is such that outer leads for connecting to a motherboard are formed on a flexible printed circuit film. However, the printed circuit film is characterized in that a reinforcing plate is laminated on a portion of the printed circuit film other than the outer leads.

In this circuit board, since the outer leads are formed on the printed circuit film, that is, the outer leads are held by the insulating film, the arrangement state will not be disturbed even if the pitch of the outer leads is made finer. Also, the parts of the printed circuit film other than the outer leads are reinforced with reinforcing plates to form a plate shape.
It can be handled in the same way as a conventional printed wiring board.

FIG. 1 shows an embodiment of the present invention. Reference numeral 21 is a flexible printed circuit film having a required circuit pattern 23 formed on the front surface of an insulating film 22 and outer leads 24 formed on the back surface. The circuit pattern 23 and the outer lead 24 are electrically connected through a through hole 25. A reinforcing plate 26 is laminated on a portion of the printed circuit film 21 other than the outer leads 24 via an adhesive 27. Since the outer lead 24 is in the state of the printed circuit film 21, it is flexible, and the other parts are reinforced with the reinforcing plate 26, so they are in the form of a non-flexible plate.
