Abstract

PURPOSE:To make it possible to secure positively stabilized standoff without increasing the number of steps associated with soldering by satisfying the general-purpose applications of solder paste. CONSTITUTION:The surface of a stand 10b of a part mounting board 10 is made to protrude from the surface of a conductor part 10a. Under the state, wherein a circuit component 20 is mounted on the surface of the stand 10b, solder paste 30 is provided between the surface of the conductor part 10a and an electrode 20a of the component 20. The holder paste 30 passes reflow process. At this time, the component 20 is supported with the upper surface of the stand 10b. Therefore, the component 20 is mounted on the part mounting substrate 10 under the state, wherein stable standoff DELTAH is positively secured.

2. Description of the Related Art As a conventional component mounting board, for example,
It is known to have a pair of conductive portions formed on the surface by printing or the like and made of a planar ceramic such as alumina.

By the way, in the board on which the mounting parts are mounted in this way, there is a difference in the coefficient of thermal expansion between the solder and the board for mounting the parts. Therefore, there is a possibility that thermal fatigue damage may occur between them during long-term use. . In order to extend the life until this destruction, ensure the height that separates the mounted parts from the stand between the conductive parts, that is, the standoff,
Thus, it is effective to increase the distance between the conductive portion and the electrode to increase the length of the solder so that the shear stress caused by the difference in thermal expansion coefficient can be absorbed by the long solder.

Therefore, when mounting a mounting component on a conventional planar component mounting substrate, normally, as shown in FIG. 7A, first, a component mounting substrate 90 and a mounting component 91 are placed on a stand 90b. In step 1, the adhesive 92 is preliminarily fixed, and the solder paste 93 is interposed between the conductive portion 90a and the electrode 91a. Then, as shown in FIG. 7B, the solder paste 93 is melted and solidified (usually called reflow). In the substrate thus obtained, since the adhesive 92 separates the conductive portion 90a and the electrode 91a from each other on the stand 90b, the standoff Δ to some extent is obtained.
H is secured.

As another mounting method, as shown in FIG. 8A, a solder paste 94 containing high melting point particles 94a having a diameter suitable for the standoff ΔH may be adopted. In this case, the solder paste 94 is interposed between the conductive portion 90a and the electrode 91a. Then, as shown in FIG. 8B, the solder paste 94 is reflowed. Even in the substrate thus obtained, the high melting point particles 94a separate the conductive portion 90a and the electrode 91a from each other, so that a certain standoff ΔH is secured.

However, the method of interposing an adhesive agent, a component pushing solder, a tape, etc. for ensuring a standoff between the stand and the mounted component requires a step of interposing them, and In order to prevent destruction due to thermal expansion, a step of removing these after the completion of the substrate is also required.

Further, in the method of interposing an adhesive, a component pushing solder, etc. between the stand and the mounted component, the adhesive, the component pushing solder, etc. become thin due to the weight of the mounted component at the time of reflow, and a stable standoff is achieved. Is difficult to secure. Further, in the method of adopting the solder paste containing high melting point particles for ensuring the standoff, the versatility of the solder paste is lacking, and the solder after the completion of the board becomes difficult to absorb the shear stress by the amount of the high melting point particles. , There is a risk of impairing the life extension effect until destruction.

In the board on which the mounting component 20 is mounted in this manner, the linear thermal expansion coefficient β of the solder 30 is 2.4 × 10 -5 / ° C.
On the other hand, the linear thermal expansion coefficient β of the component mounting board 10
