Cold Solder Joint
Traditionally, the principle of soldering involves heating components that are to be soldered together, in order to raise their temperatures to that of the melting point of solder. Modern electric soldering irons are often temperature controlled using an electronic thermostat, though the more basic fixed temperature irons may be “thermally balanced” which means that their mechanical design helps to regulate the temperature of the tip.Recently a device called a “cold soldering iron” arrived on the market that is radically different from any traditional soldering iron. It is a battery-powered cordless iron produced exclusively by Hyperion Industries Inc. under their Cold Solder Joint trademark
