By the way, as shown in FIG. 3, formation of a conductor circuit on a semiconductor mounting substrate is performed by first forming a plurality of conductor circuits and semiconductor mounting portions for the semiconductor mounting substrate on one large substrate material. Is formed in advance, and a large number of plating leads connected to each conductor circuit and communicating to the outside of the portion to be the semiconductor mounting substrate are formed. Then, the conductor leads are plated at the same time through the plating leads formed in this way,
In the final outer shape processing, the substrate is cut along the outer edge of the outer shape. In such a manufacturing process, since the plating lead is cut at the same time as the cutting of the substrate, the peripheral edge of the plating lead is exposed on the outer periphery of the substrate on the outer peripheral edge of the semiconductor element mounting surface side. It remains.

However, in recent years, the degree of integration of electronic components called semiconductor elements has become extremely dense, and therefore, the semiconductor mounting substrate for mounting the electronic components must also be highly densified. That is, the plating leads (1
As shown in the conventional view of FIG. 2, a plurality of 3) are formed between the lands (14) of the through holes. Therefore,
In the semiconductor mounting substrate that has been subjected to the above-described outer shape processing, the plating lead terminal end portion remains on the outer peripheral edge portion on the semiconductor element mounting side in a state of being intimately and exposed to the outer peripheral edge portion of the substrate.

By the way, in such a semiconductor mounting board, the lead pins are fixed or mounted on a mother board, so that they are immersed in molten solder in a later step. In this case, the solder is a part of the conductor circuit. It may adhere not only to the surface of, but also to the space between the plating leads. That is, when the spacing between the plating leads is narrow, the solders on the surfaces of both plating leads adhere to each other, resulting in a bridge-like state. In such a state, an electrical short circuit occurs between the plated leads, and the semiconductor mounting board becomes defective.
Furthermore, this problem also occurs when the distance between the conductor circuits located between the lands of the through holes is too small.
