Connector and manufacturing method thereof

A manufacturing method of a connector, comprising:

• providing a guide pin module, wherein the guide pin module comprises a base, a metal guide pin, and a glass sealing layer, wherein the base comprises a perforation hole, the metal guide pin is inserted into the perforation hole, and the glass sealing layer is disposed at the perforation hole and wraps around part of the metal guide pin;
• providing a circuit board on one side of the guide pin module, wherein the circuit board comprises a mounting hole corresponding to the perforation hole, and the metal guide pin is inserted into the mounting hole;
• disposing a conductive cover at the mounting hole, wherein the conductive cover is connected to a top of the metal guide pin and protrudes from the circuit board;
• and
• performing a soldering step to bond the conductive cover to the circuit board, so that the metal guide pin is electrically connected to the circuit board through the conductive cover.
