What Are Hot Tweezers?
Hot tweezers are repair tools with a tweezer-like tip.
Hot tweezers are a type of soldering tool that can directly grab components. They can be used with lead-free solder and have a remote switch design with the power supply attached to the main unit, increasing safety and saving power. Since they can be powered from an electrical outlet, they can be used anywhere an outlet is available. They also have features such as resistance to heat, abrasion, and erosion by alkalis and acids, and solder does not adhere to the heating component. Some tweezers are designed to prevent static electricity in the tweezer tips and some are designed to be barrier-free, allowing use regardless of the user’s dominant hand.
Uses of Hot Tweezers
Hot tweezers are suitable for working with pinpoint accuracy on high-density components such as SMD-dense circuit boards because they can directly transmit the sensation of the hand to the work as tweezers do.
Since substrate chips are typically soldered onto boards, they must be de-soldered before removal. With hot tweezers, in which the heater and tweezer portions are integrated, the solder can be melted while grabbing the chip component with the tweezers, allowing the chip to be removed without damaging the board.
Principle of Hot Tweezers
Hot tweezers consist of a station that includes the power supply and other essential components, a power switch, a heating unit on the main body, and tweezers for performing the work. By adopting a constant power control system, heat can be supplied in seconds.
