发明名称 Method and mask assembly for forming solder bodies on a substrate
摘要 A method for forming solder bodies on a substrate includes: positioning a first mask plate, which is formed with at least one first through-hole, on the substrate; filling the first through-hole with a first solder paste so as to form a first solder body on the substrate; positioning a second mask plate, which is formed with at least one second through-hole and at least one recess spaced apart from the second through-hole, on the substrate in such a manner that the first solder body is received in the recess; and filling the second through-hole with a second solder paste so as to form a second solder body on the substrate.
