1 is an external connection terminal, 2 is an exterior molded resin, and a circuit element is built inside. In general, the position of the external connection terminal 1 pulled out from the exterior resin is the position of the internal circuit element (
(not shown), it is often located near the center of the exterior side of the chip component. As shown in the figure, the external connection terminal 1 pulled out in this way is folded into an L-shape, and the terminal is located at the bottom and bottom of the side of the exterior. In this case, there is no problem with reflow soldering, but when using dip soldering, there are no terminals on the upper side of the exterior, so the soldering does not work well, and dip soldering is difficult for high-density mounting with many components on one board. There are reliability problems.

The external connection terminal is constructed by bending it along the side, and a notch is provided in a part of the resin-molded part of the external connection terminal. The raised piece is exposed to the outside of the exterior molding resin, and this allows the dip half "1" of the chip component in which the circuit element is insert-molded.
This will improve the reliability of the product.

外部接続用端子が位置する構造であれば良い。Figure 2 shows a chip component having an external connection terminal according to an embodiment of the present invention. In Figure 2, 3 is an external connection terminal of the chip component, and a cut is made in a part of the resin-molded part. It has a cut-and-raised piece 3a that is folded on the side opposite to the board at the time of mounting and exposed along the side surface during resin molding. As a result, the external connection terminals 3, which are normally located near the center of the side surface of the chip component, or from less than half to the bottom surface, can be located on most of the side surface of the chip component. External connection terminal 3 like this
According to the chip component having the above, high reliability of dip soldering can be realized even in high-density mounting where many components are mounted on one board. In addition, in this embodiment, a cut is made in a part of the resin mode portion of the external connection terminal 3, and a cut and raised piece 3a is provided by bending it and exposing it on the side surface to enable dip soldering. The method of exposing the external connection terminal 3 is not limited to the one shown in Fig. 2, but can be done by making a notch in a part of the external connection terminal 3 located inside the resin mold and bending it to the side opposite to the board at the time of mounting. Any structure may be used as long as a cut-and-raised piece is provided and the external connection terminal is located on most of the side surface.

When this cut and raised piece is molded with resin, it is exposed on the side, and when a chip component with an insert-molded circuit element is attached to an electronic circuit board and dip soldered, the cut and raised piece exposed on the side is exposed. The solder rises through the raised piece, which has the excellent effect of improving the reliability of dip soldering. This has the effect of expanding the range of applications for chip components.
