<p>PURPOSE: To prevent the generation of a solder bridge which is easily generated, when a component of a terminal of narrow pitch is soldered. CONSTITUTION: An excess solder absorption region 24 which is not provided with a solder resist 20 is provided to a tip side of a terminal 14, rather than to an end part 22A of a solder pad 22 in the solder resist 20. If much solder paste is attached on the solder pad 22 when the terminal 14 is soldered, excess solder 28 which is fused by the heat of a heating heater travels through a terminal 14 and flows to the tip direction of the terminal 14, inside an excess solder- absorbing region 24. Since the excess solder 28 does not go over the solder resist 20 between the terminals 14, a solder bridge is not formed.</p> |
