As described in Publication No. 5, the circuit pattern is coated with a molding resin, and the shape of the injection molded object can be formed arbitrarily, and the electric component,
It had advantages such as being able to easily mount electronic components. However, in mounting electrical components and electronic components, in order to solder the connection with the electrical components and electronic components,
It is necessary to form a solder film on the surface of the circuit pattern in advance. Therefore, a molding material with a melting point higher than the soldering temperature is required, and the resin elasticity naturally deteriorates. Therefore, if it is necessary to hold electrical or electronic components,
When injection molding the resin of the molded substrate, the holding portion is formed using a mold. With the same high melting point polymer material, the amount of deflection during holding was small and there was a high possibility of breakage.

First, the circuit pattern is covered with a high melting point and high rigidity resin, and then electrical parts and electronic parts are coated. The mounting portion, that is, the portion for fixing the electrical components and electronic components, is made of an elastic, low-melting resin. In addition, considering the high temperature during soldering, molding with thermosetting resin is also effective. In this case, the same purpose can be achieved by forming the part that holds and fixes the electrical and electronic components with a material with low hardness. It is something that will be done.

Since it is coated with resin, there is no deformation or melting of the resin during soldering.

無機質フィラー含有等制限されるものではない。[Embodiment] An embodiment of the present invention will be explained below with reference to FIG. Although FIG. 1 is a partial cross section of the present invention, the circuit pattern 4
is a copper plate molded into a circuit shape. The circuit pattern 4 has a thin film precoat part 5 in which solder material is formed in advance on necessary parts, and openings 4a for mounting electrical components and electronic components, and furthermore, a front and back resin is applied to the circuit pattern 4 during injection molding. Holes 2a are machined to maintain close contact. The high melting point molding resin 1 is injection molded to cover the entire circuit pattern 4, and a space 1b for mounting electrical components and electronic components and a soldering space 1a are formed. The electrical component/electronic component holding parts 2 and 3 are integrally molded with a substrate made of high melting point molded resin 1, and preferably are inserted into the opposite side 2 through the hole 2a of the circuit pattern 4.
By introducing up to b, the adhesion between the electric component and the electronic component holding portion 2 is improved. Various electrical components and electronic components 6 and 7 are mounted on this board as shown in FIG. The electrical components and electronic components 6 and 7 are fixed to the board. The electrical components and electronic components 6 and 7 are made of an elastic low-melting resin.
It is reliably held on the substrate by the elastic reaction force. On the other hand, when a thermosetting resin is used as described in patent claim 2, it is also fully satisfactory to use a high hardness resin instead of a high melting point resin, and a low hardness resin instead of a low melting point resin. It is possible. The high melting point resin mentioned here is one with a melting point of 250°C or higher or the heat distortion temperature of 260°C or higher according to ASTM test D648, and the low melting point resin is one with a melting point of 250°C or lower or a heat distortion temperature according to the same test. The temperature is 260°C or less. Furthermore, these resins are not limited to single substances or those containing inorganic fillers.
