- the presence of the above-mentioned step is caused by the vicinity of the surface of the second opening. To prevent separation from reaching the first opening.
- the second structural member 22 and the circuit board 1 are arranged above and below the first structural member 21 which is the center of the laminate, and the characteristics (thermal expansion characteristics, etc.) and the shape (particularly, The thickness of the laminate is a symmetrical structure in the vertical direction, and large warpage of the entire laminate does not occur. As a result, the manufacturing efficiency can be further improved and the electronic components can be skipped. More reliable prevention of protrusion is achieved. In addition, high-quality, inexpensive thin polyester films are actively used, and quality improvement and cost reduction can be achieved more reliably.
- the IC card shown in this embodiment is the one shown in FIG. 4, and is above the second structural member 22 having the opening 225 similar to that of the above-described first embodiment, and further similar to the opening 215.
- the structural auxiliary member 23 provided with the auxiliary opening 235 of the first embodiment is disposed. Further, a circuit board auxiliary member 24 was disposed below the same circuit board 1 as in Example 1.
- the thickness of the second structural member 22, the structural auxiliary member 23, the circuit board 1 and the circuit board auxiliary member 24 is 60 ⁇ m, and the overall thickness of the IC card is IS 0. This is the same as the IC card of Example 1 except that the thickness of each adhesive layer was changed to conform to the standard.
- Each of the structure support member 23 and the circuit board auxiliary member 24 is made of the same film as the polyester resin used for the circuit board 1 of the first embodiment. Therefore, the second structural member 22 and the circuit board 1, and the structure auxiliary member 23 and the circuit board auxiliary member 24 each have a “pair” relationship in the above-mentioned vertical object structure j.
- the second structural member 22 is shaped so that the encapsulant layer 3 is eroded and embedded, thereby preventing the electronic components from jumping out more than in the first embodiment. .
- the present IC card also has a symmetrical vertical cross-sectional structure, a large warp does not occur even when electronic components are mounted.
- the circuit board 1 the first structural member 21, the second structural member 22, the structure auxiliary member 23, and the circuit board auxiliary member 24, a fairly thin (60 / m) film is used. Therefore, a material which is inexpensive but excellent in strength and the like is used.
- FIG. 5 illustrates a modification of the second embodiment in which a similar effect can be expected.
- a modification of the first embodiment is illustrated in FIG.
- the meanings of the symbols in these figures are the same as those used in Figs.
- Industrial applicability In the electronic component mounting device of the first and second inventions, even if the device is bent, the encapsulant layer sealing the electronic component is locked to a circuit board or a structural member within its outer peripheral line, Prevents electronic components from jumping out. Moreover, since the manufacturing is simple, it can be a very inexpensive electronic component mounting device.
- the electronic component mounting apparatus in addition to the effect of the second aspect described above, is further strongly bent, and the encapsulant layer that seals the electronic component is opened from the second opening. Even if it is crowded, the separation only appears near the surface of the second opening, but does not reach the first opening. Therefore, problems such as jumping out of the electric appliance are less likely to occur.
- the manufacturing of this apparatus is such that the first and second structural members are stacked and arranged on the upper surface side of the circuit board to mount the electronic component. After that, it is sufficient to seal with an encapsulant and arrange the skin material as necessary, and there is no need to manufacture an IC module with a complicated structure that has been conventionally implemented. Therefore, it can be manufactured easily and efficiently.
- the structure of this apparatus is such that, for example, when electronic components are mounted, a temperature change occurs in the circuit board and each structural member, and thermal expansion occurs. However, even if shrinkage occurs, the circuit board and the second structural member sandwich the first structural member and expand and contract in substantially the same state. That is, the electronic component mounting apparatus is less likely to warp during manufacturing and use.
- this electronic component mounting apparatus in addition to the effects of the fifth aspect described above, a thin polyester film which is inexpensive but has excellent thermal expansion characteristics is positively used. That is, this electronic component mounting apparatus is high quality and extremely inexpensive.
- the electronic component mounting apparatus particularly presents an IC force as an application in which the effects of the first, second, third, fourth, fifth, or sixth aspects described above are required to be extremely prominent. are doing.
