Efforts have also been made to prevent the material from protruding. However, if the material of the substrate 1 is glass epoxy or the like, it is difficult to provide the recess 7, and this method is disadvantageous in that it is not practical.

はシステムの動作を終了する。This setting is performed, for example, by detecting a mark on the substrate 1 and moving the NC table 10 in the X-Y direction so that the mark is at a predetermined position. Next, the solenoid of the applicator is operated to start dispensing the resin, and the air pressure of the microdispenser 11 is controlled so that the amount of resin dispensed is the optimum amount for forming the microdam. When coating starts, ultraviolet rays are irradiated from the ultraviolet lamp 14, and the energy necessary for curing the resin is controlled. Next, NC table 1
It is determined whether the circuit board 1 on the board 0 has stopped at the specified position (starting position #), that is, whether the resin coating has completed one cycle on the board 1 and has finished forming the band-shaped dam. Ba,
The above-described operations such as moving the NC table 10, applying the resin, and irradiating the ultraviolet rays are repeated. When the NC table 10 stops at the designated position, the formation of the band-shaped dam 9 has been completed, and the process proceeds to the first step. In this step, it is necessary to determine whether or not the irradiation control system should be stopped, that is, a plurality of the circuit boards l are manufactured in succession on a large board, and whether or not the strip dam 9 is formed on all of the plurality of circuit boards l. Determine whether or not. If there remains a circuit board 1 on which the strip dam 9 has not been formed, the position of the next board 1 is corrected, and then the above-mentioned movement of the NC table 10, resin coating,
Performs operations such as ultraviolet irradiation and stop position determination. Further, when the formation of the band-shaped dams 9 on all the circuit boards 1 is completed, the operation of the system is ended.
なお、ダム9の形状位置はROMまたはRAM内に記憶

記の動作を繰り返し、何組ものダム9を形成することが
できる。Note that the shape and position of the dam 9 is stored in the ROM or RAM, and by using this stored data, the above operations can be repeated on a large substrate to form many sets of dams 9.

Further, since the dam 9 can be easily formed into any shape, it is possible to coat the dam 9 into any shape including minute parts. Furthermore, in the present invention, there is no need to provide the recess 7 as in the conventional case, so either a resin substrate or a ceramic substrate can be used as the substrate.
