Abstract

PURPOSE:To provide a new method for accurately forming a file thick film circuit at a low cost. CONSTITUTION:A film 4 is uniformly coated with a thick film circuit forming material layer 5 on one side thereof. The circuit forming material layer 5 is so located as to closely contact with a substrate 1 on which a circuit is to be formed. A thermal head 3 selectively applies thermal energy to the film from the other side thereof to selectively transfer the circuit forming material layer 5 to the substrate 1. Subsequently, the substrate 1 has a pattern formed, and is subjected to a heat treatment in an suitable atmosphere at a suitable temperature therefor to obtain a thick film circuit.

Conventional methods for forming thick film circuits include a screen printing method, a drawing method for drawing a circuit with a pen, and an etching method for forming a circuit by etching after applying a predetermined circuit forming material on the entire surface. Most of them are manufactured by the screen printing method by comparing productivity and reliability. Such a screen printing method is performed as follows.

However, the conventional screen printing method has some problems. That is, first, a printing screen is required for each pattern to be formed into a circuit. Especially when producing a wide variety of small quantities,
There is a problem that the cost of the screen occupies a large weight in the product cost. Further, when changing the type of product to be produced, it is necessary to replace all the screens and adjust the printing conditions, and particularly adjusting the conditions of the resistor requires a great deal of time. Further, although CAD has become the mainstream in the recent design of thick film circuits, there is a drawback that the CAD data cannot be utilized to the maximum extent in the printing process. In addition, since the screen uses a screen in which metal fine wires are knitted, it expands as the number of times of printing increases, it is difficult to form an accurate circuit, and it is necessary to replace the screen every several thousands to tens of thousands of shots. Also, the emulsion used had a long life, and the frequency of replacement was further increased.

Secondly, since the paste to be printed is composed of a circuit-forming material, an organic component and a solvent, its viscosity and physical properties change in proportion to the passage of printing time, and a film of a printed pattern is formed.

Fourthly, when the resistor paste is printed by the screen printing method, there is a drawback that the thickness of the printed resistor is difficult to be uniform. That is, as shown in FIG. 5, when the conductors 17a and 17b are printed, dried, and heat-treated on the surface of the base material 12, and then the resistor 18 is screen-printed in the direction of the arrow 21, the resistor film of the conductor 17a is formed. Thickness 1
There is a difference in thickness between the resistor film thickness 20 and the resistor film thickness 20 between the conductor 9 and the conductor 17b, and the portion 20 is inevitably thin. Particularly in the case of a minute resistance pattern, the interval between the conductors 17a and 17b is narrow, and the variation in the film thickness becomes more prominent. As a result, when the resistors having different pattern sizes are printed on the same screen, the resistance value becomes difficult depending on the design. Fifth, in the screen printing, the substrate to be printed needs to be a flat surface in principle, and there is a problem that the substrate having an aspect cannot be printed.

According to the circuit forming method of the present invention, for example, individual heating elements of a thermal head formed with a large number of equal pitches are controlled in accordance with CAD data or the like which is designed in advance and a voltage is applied to form the circuit. Since the material is transferred, the above-mentioned screen becomes unnecessary, and as a result, it becomes unnecessary to replace the screen due to the elongation of the wire material of the screen and the deterioration of the emulsion, which reduces the cost of the screen and the replacement of the screen during production. It also eliminates the loss of time and greatly reduces costs and simplifies work processes. Also, C
Since the circuit formation process can be controlled by the AD data, a completely automated line construction can be achieved. Further, as described above, a thin film for forming a circuit is formed on the film and used in a semi-dried state, so that the physical characteristics of the circuit forming material are less likely to change within the working time, and therefore the film of the formed circuit is formed. The thickness and width hardly change, and stable circuit formation is possible.

Further, since the resistor material thin film having a uniform film thickness formed in advance is thermally transferred, there is very little variation in the resistor film thickness in the conventional circuit conductor portion, and stable resistance characteristics can be easily obtained. Can be formed with good reproducibility. Further, since the circuit-forming material is thermally transferred from the film formed in the semi-cured state on the film, the transferred circuit-forming material is in the tack-free state, so that the next circuit-forming operation can be continued. .. In addition, the method of the present invention has a great feature that the substrate does not need to be a flat surface and a circuit can be easily formed on a curved surface because the portion in contact with the substrate is only the heating element portion. There is.
