Method for welding electric connector on circuit board

The invention relates to a method for welding an electric connector on a circuit board, which comprises the following steps of: inserting a side surface positioning pin of the electric connector on the side surface of the circuit board, and then welding the side surface positioning pin and the circuit board by using a steel mesh. The steel mesh is provided with a steel mesh opening used for depositing solder paste, and the steel mesh opening extends outwards for a certain distance along the board edge of the circuit board. According to the invention, the electric connector can be firmly and reliably welded on the circuit board, and the tensile resistance is improved. 一种电连接器在电路板上的焊接方法，先将所述电连接器具有的侧面定位针插装在所述电路板的侧面，然后再将所述侧面定位针与所述电路板之间藉钢网进行焊接。所述钢网具有用于沉积锡膏的钢网开口，所述钢网开口沿所述电路板的板边向外扩展一段距离。本发明能够将电连接器牢固可靠地焊接在电路板上，提高了抗拉力。
