PURPOSE:To supply a proper quantity of solder corresponding to each part, in a solder printing metal screen, by forming minute quantity solder patterning parts and large quantity solder pattern parts to a thin half-etching part in a piercing manner. CONSTITUTION:A thin half-etching part 2 is formed to the predetermined area of a solder metal screen 1 and not only a plurality of minute quantity solder pattern parts 3 but also a plurality of large quantity solder pattern parts 4 are formed to said area in a piercing manner. Then, a solder paste 7 is printed through patterning parts 3, 4 to obtain a thick film printed board 8 having large solder quantity parts 9 and minute solder quantity parts 10 formed thereto. Next, loading parts 11 are respectively soldered to the large solder quantity parts 9 and the minute solder quantity parts 10. By this method, a proper quantity of solder corresponding to an indivisual part can be supplied and the reliability of solder connection can be enhanced. |
