Process for soldering electric connector onto circuit board

Abstract

In a process of soldering an electric connector on a circuit board, the connector has an insulator and a plurality of leads mounted inside the insulator. Each lead has a first end extending into a soldering terminal to a bonding surface of the insulator. A soft solder paste is dispensed over a bonding surface of the circuit board. The soldering process inserts the soldering terminal of each lead in the soft solder paste and applies heat to the soft solder paste to bond the soldering terminal and the circuit board together. The direct insertion of the soldering terminal of the lead into the soft paste on the circuit board minimizes the contact area between the lead and the circuit board and prevents the solder paste from being unduly spread, causing short circuit. Furthermore, the yield and soldering reliability are increased and the production cost is reduced.
