The transfer body (1) and the substrate (3) are brought close together and fitted into the fitting groove (4a), the thick film paste (■) is pressed onto the substrate (■), and then the substrate (■) and the pressing body (3) are connected as shown in Fig. 1(e). (When 4 is returned to its original position, the thick film paste ■ adheres to the substrate ■, and the transfer is completed. However, in such a configuration, the force pressing the thick film paste ■ against the substrate a is
It is determined by the relationship between the width of the fitting groove (4a) in 4) and the thickness of the substrate (3), so if the groove width is narrowed to increase adhesion, the thickness of the thick film will be reduced as shown in Figure 2. The shape may collapse, the thick film paste may gather toward the edges, or cracks may occur.Also, if the groove width of the song groove (4a) is widened to avoid this phenomenon, the groove width will be widened as shown in Figure 3. In this case, the adhesion of the thick film paste becomes poor and the edges tend to curl around.In this way, with the conventional configuration, it is difficult to adjust the pressing force on both sides of the substrate, making it difficult to transfer a uniform thickness with good adhesion. It was difficult.
