Resistance Soldering

Resistance Soldering Overview

Resistance soldering is a technique for creating solder joints using electrical resistance to generate heat. Instead of a heated tip like a traditional soldering iron, resistance soldering uses a controlled electrical current passed through a resistive material to create a localized hot spot that melts the solder.

Advantages of Resistance Soldering

• Faster Soldering: Heat is instantaneous and concentrated, leading to quicker solder flow and faster joint creation.

• Precise Control: The heat is highly localized, minimizing risk of damage to nearby components.

• Reduced Heat Transfer: Cooler handpiece reduces operator fatigue and risk of burns.

• Longer Tip Life: Electrodes last longer than soldering iron tips, reducing replacement costs.

• Clean and Efficient: No need for constant tip re-wetting, leading to cleaner work.

Disadvantages of Resistance Soldering

• Higher Initial Cost: Resistance soldering equipment typically has a higher upfront cost compared to traditional soldering irons.

• Limited Applications: May not be suitable for all soldering jobs, especially those requiring extensive heating or rework.

• Electrically Damage: May damage electronic components with high current if allowed flow through more than 1 pin of the component.
