The present invention relates to a method for manufacturing a high functional soldering tip and a soldering device, and more particularly, to maximize the heat generation performance of the tip for melting the solder or silver solder that serves as a bonding material in the automatic and manual soldering device With the device, it is intended to provide a manufacturing method and a shape of the tip for producing a tip for melting the bonding material.

As a method of joining two different materials to each other, a welding method in which a material to be joined is melted and a bonding material is melted and bonded to each other, and a soldering method in which the material to be bonded is melted and melted together without melting. Soldering).

Soldering is a method of joining two different materials by melting only the bonding material without melting the materials when joining two different materials. The soldering method is distinguished from welding in which the bonding material is melted and joined. The joining material used for soldering is also called soldering or soldering. The solder material has good bondability with the metal to be joined, has an appropriate melting temperature and fluidity, is sufficiently spread by capillary action, and must be uniform and stable in the molten state. Commonly used solders are lead-tin alloys, tin serves as adhesion, and lead serves as an increase in strength and melting point. Specifications are 5 to 98% tin, and generally used are 50% tin solder (complete solidification temperature of about 185 ° C, complete melting temperature of about 215 ° C). 95% tin solder (183 to 224 ° C.) is used for joining special electronic parts or parts in contact with food. Since 60-65% tin solder has a low melting point (183-190 degreeC), it is excellent in adhesiveness and is used as a precision solder of a narrow gap.
