Abstract
In a mounting structure, a housing is supported while being raised from a printed circuit board by first molten solders provided between the housing and the printed circuit board, the supported housing is positioned such that terminals come to be located in the centers of lands by a self-alignment effect of second molten solders provided between the terminals and the lands and is fastened onto the printed circuit board by screws and the like with the first and second molten solders naturally cooled. The connector mounting structure is inexpensive and has a good durability and enables the miniaturization of a connector and a narrow arrangement of terminals.

A connector mounting structure for electrically connecting terminals extending from a housing with lands on a circuit board by soldering, comprising:
- a first molten solder provided between the housing and the circuit board for supporting the housing while raising it from the circuit board;
- a second molten solder provided between a terminal and a land for positioning the supported housing such that the terminal come to be located in the center of the land by the action of surface tension;
- and
- a fastener for mechanically fastening the positioned housing on the circuit board with the fist and second molten solders solidified by cooling.
A connector mounting method for electrically connecting terminals extending from a housing with lands on a circuit board by soldering, comprising:
- a first step of supporting the housing while raising it from the circuit board by a first molten solder provided between the housing and the circuit board;
- a second step of positioning the supported housing such that the terminal come to be located in the center of the land by the action of surface tension of a second molten solder provided between the terminal and the land;
- and
- a third step of mechanically fastening the positioned housing onto the circuit board with the first and second molten solders solidified by cooling.
