A PIN AND A PRINTED CIRCUIT BOARD

摘要

A pin and a printed circuit board are provided. The pin includes a pin body and an insertion head. The insertion head is disposed on an end of the pin body and includes a base and a guide post. The shape of the base is a cylinder, the bottom of which is located on the end of the pin body. The shape of the guide post is a prism, which is coaxially connected to the base. The projection of a circumcircle of a cross section of the guide post is overlapped with that of a cross sectional circle of the base along the direction of an axis of the guide post. The advantage of the prevent invention is to decrease the tilt of the pin body after inserted, reduce the solder material between the base and the insertion hole, and improve the welding quality.
