It is difficult to solder nibs such as BX with a large number of terminals and the terminal spacing is narrow, and it takes a lot of time. t-must be used. Furthermore, wiring that intersects on a plane must be made into through holes, which complicates the manufacturing process and increases costs.

etc.) to 30 vots or less (preferably 5 to 10 vots)
The resin layer 3 for the thermofusible layer (thermoplastic@B\I mainly unreacted thermosetting resin) mixed in (T%) was applied and dried without pressing. However, soldering is done at 9 points 4 to 4 on all lines. The parts 6 to 6 corresponding to the connection points 5 of the integrated circuit and the connection points of capacitors, etc., are masked and coated with resin as marks of connection pupils, and resin l1lrt is formed and there is no φ. In this state, the resin layer 5 is insulating in all directions.

Therefore, in Step 9 of FIG. 2, the lead pins of the integrated circuit 7 are thermally fused to the corresponding conductive pattern portions by heat fusion. The heat-sealed portion becomes conductive only in the thickness direction, and electrical continuity is established between the lead bin and the conductive pattern.

Since all the circuit elements etc. are connected by thermal fusion, even if there are a large number of connection terminals, they can be easily connected, and liquid crystal panels etc. can also be easily connected. Furthermore, since the resin layer 3 is insulating in all directions except for the heat-sealed portions, short circuits between patterns due to wire scraps or the like can be completely prevented.

That is, the end portion of the conductive pattern of the flat cable 9 is heat-sealed to the heat-sealing resin layer 10 so that the conductive pattern 11 straddles the entire conductive pattern 11 and forms a three-dimensional intersection.

After coating, the resin layer 3 may be dried by applying a full pressure I- to the entire surface. In this case, the entire surface becomes anisotropically tetraelectric, so even if the pressure is small when thermally fusing circuit elements, etc. You can make a conduction sound in the N area.

As described above, according to the present invention, a circuit board is coated with a heat-sealing resin layer that is conductive only in the thickness direction by heat-sealing under pressure. etc. can be connected to Dutch studies, and items that cannot be soldered such as liquid crystal panels can also be connected. What's more, it's easy to use $i+ for intersecting wires with grade-separated intersections? 7 wiring, and fewer conductive particles are mixed in, resulting in stronger adhesive strength.
