Zusammenfassung: | The utility model discloses a solder thief pad for preventing a multi-pin DIP element from over-wave soldering and tin connection, a solder thief pad is added to a bottom wiring layer of a PCB, and the solder thief pad is arranged at one side of a PCB pad and is opposite to a wave soldering plate passing direction. The distance between the solder thief pad and the edge of the PCB pad is 0.8 mm, the width of the solder thief pad along the wave soldering direction is 4mm, and the length of the solder thief pad is equal to the width of the PAD. According to the utility model, through the design of adding the solder thief pad on the BOT layer of the PCB, the problems of tin connection and short circuit behind the furnace are solved, and the problems of tin connection and short circuit caused by the fact that the PAD interval of a multi-pin DIP element is small, the manufacturing process capability of a PCB manufacturer is limited and a white oil block cannot be manufactured are solved.
