Abstract:
A solder jointing system comprising:a chamber open to the outside through openings at opposite ends of the chamber through which a solder-adhered object is passed, and the chamber having a heating/melting area and object carrying areas arranged adjacent to the heating/melting area with all areas of the chamber being open to the outside through the openings for passing the solder-adhered object; said openings having no physical barriers capable of closing or blocking the openings; a carrying mechanism for carrying the solder-adhered object into the heating/melting area; a formic-acid supplying device for supplying a formic acid into the heating/melting area; an exhausting device for exhausting a gas from the heating/melting area and its neighboring area to create a lower a pressure in the heating/melting area as compared to pressure outside the solder jointing system; a heating device for heating directly or indirectly the solder-adhered object in the heating/melting area; and an air-stream suppressing device for disturbing a gas flow between the heating/melting area and the carrying areas.
