    • An adhesive containing at least two main components, and which is capable of being gelled to make it pressure-sensitive, of being photopolymerized and of being thermally polymerized, is applied at selected positions on a printed circuit substrate on which electronic parts are to be loaded. Ultraviolet rays are irradiated on the adhesive, to gelate the adhesive thereby to realize the pressure-sensitive adhesion ability by reaction of a photopolymerization functional group of the adhesive. After loading the electronic parts on the adhesive, the adhesive is hardened by reaction of a thermal polymerization functional group by heating. Thereafter, electrodes of the electronic parts and conductive lands of the printed circuit substrate are soldered.

    • Disclosed is a method for forming thick film circuits or the like to be used when forming elements such as conductors and resistors on a thick film circuit board. The method is performed with a writing head for storing paste to form patterns and which lowers and approaches an arbitrary point in close proximity to the board of a thick film circuit and while same state, moves laterally to another other arbitrary point along the surface of the board, and then ascends to be separated from the board. The paste in the writing head is pressurized to be forced out of the head before the writing head begins to move laterally such that the paste is immediately applied on the board when the writing head begins to move laterally. This pressurization of the paste is stopped before the writing head finishes its lateral movement, so that the extrusion of the paste may be stopped the moment the writing head finishes the lateral movement. As a result, blurring or blotting at the beginning and ending part of the pattern writing may be prevented, so that patterns may be formed at high speed and with high precision.
