The main technical parameter of the contact soldering station is the power. The power determines the operation convenience and soldering effectiveness. The modern stations have power from 10 to 200 W and more. The most common are the models with 50-80 W power. The higher is the power the more amount of heat you may transmit for the same time.
A hot air gun or hot air station is used to heat devices and melt solder, and specialised tools are used to pick up and position often tiny components. A rework station is a place to do this work—the tools and supplies for this work, typically on a workbench .
The stubs are then easy to melt off and clean with a soldering iron. Obviously this technique entails the destruction of the IC. Another method is to use a heat gun or pencil butane torch and heat up a corner, and gently pry it off, working the torch down the leads. This method often leads to traces getting lifted off the PCB where a lead did ...
Resistance soldering is soldering in which the heat required to melt the solder is created by passing an electric current through the parts to be soldered. When electric current is conducted through any metal, heat is generated; when that current is confined to a smaller cross-sectional area, the heat produced in the entire circuit is ...
The tip of this apparatus is split into two sections that completes an electrical circuit when a low electrical resistance is placed across the tip; e.g. metallic contacts, or solder. [1] With a current flowing, the resistance of both the solder and the tip produces enough heat to increase the temperature beyond the melting point of solder.
It supplies heat to melt solder so that it can flow into the joint between two workpieces. A soldering iron is composed of a heated metal tip (the bit ) and an insulated handle. Heating is often achieved electrically, by passing an electric current (supplied through an electrical cord or battery cables) through a resistive heating element .

Reflow soldering is a process in which a solder paste (a sticky mixture of powdered solder and flux) is used to temporarily attach anywhere from one to thousands of tiny electrical components to their contact pads, after which the entire assembly is subjected to controlled heat. The solder paste reflows in a molten state, creating permanent ...
