Accta 301 soldering station with hot air gun and soldering iron. They use a hot air stream for heating up the components. Hot air is focused on the certain area using special hot air nozzles. Usually soldering hot air guns are capable of providing temperatures from 100 to 480 °C.
A soldering station has a temperature control and consists of an electrical power supply, control circuitry with provision for user adjustment of temperature and display, and a soldering iron or soldering head with a tip temperature sensor. The station will normally have a stand for the hot iron when not in use, and a wet sponge for cleaning.
A gun may include a two-stage trigger to give two heat settings. Tips designed for cutting and shaping plastic are available; soldering guns for general home use may be supplied with a kit of different tips. The temperature of the soldering tip is regulated manually by holding the button until the solder melts, and then releasing it.
An important consideration is peak temperature, which is the maximum allowable temperature of the entire process. A common peak temperature is 20–40 °C above liquidus. [1] This limit is determined by the component on the assembly with the lowest tolerance for high temperatures (the component most susceptible to thermal damage).
The split tip of a ColdHeat soldering iron. The first two products were soldering irons powered by alkaline batteries.The manufacturer claims this soldering iron is unique in that its Athalite tip undergoes a temperature change from ambient temperature to approximately 800 °F (427 °C) and back to ambient within three seconds when the tip is removed from the work.
The glass solder has to flow and wet the soldered surfaces well below the temperature where deformation or degradation of either of the joined materials or nearby structures (e.g., metallization layers on chips or ceramic substrates) occurs. The usual temperature of achieving flowing and wetting is between 450 and 550 °C (840 and 1,020 °F).
Temperature-controlled irons have a reserve of power and can maintain temperature over a wide range of work. A soldering gun heats a small cross-section copper tip very quickly by conducting a large AC current through it using a large cross-section one-turn transformer; the copper tip then conducts the heat to the part like other soldering irons.
The "Scope" soldering iron is a tool for soldering with lead-tin alloys, made in Australia since 1950, and intended for occasional or intermittent use.It has the virtue of quickly coming up to soldering temperature (~300C) and delivering considerable heat to a small area, but requires care to avoid overheating.
