プとなる。Next, the operation will be described. The component is placed on the printed wiring board and is soldered and fixed by the automatic soldering device. At that time, when the flux and the solder 3 come up to the component side from the slit or the square hole portion 2 in FIG. By providing the weir 5 around the square hole portion 2 by stacking the conductor 6, the solder resist 7, and the symbol print 8, it is possible to prevent unnecessary flux and solder from flowing into the circuit portion where the component is present. In the above embodiment, the reason why the weir 5 is provided by stacking the conductor 6, the solder resist 7, and the symbol print 8 is that the weir 5 can be formed in the manufacturing process of the printed wiring board, and in other components, a new manufacturing process is performed. Is required, resulting in increased cost.
