Copper content increases hardness of the alloy and inhibits dissolution of soldering iron tips and part leads in molten solder. Sn 62 Pb 37 Cu 1: 183 [17] Pb: Yes: Similar to Sn 63 Pb 37. Copper content increases hardness of the alloy and inhibits dissolution of soldering iron tips and part leads in molten solder. Sn 63 Pb 37 P 0.0015-0.04: 183 ...
The tip of the bit (commonly iron plated to reduce erosion) is kept wetted with solder ("tinned") when hot to assist soldering, and to minimize oxidation and corrosion of the tip itself. After inserting a through-hole mounted component, the excess lead is cut off, leaving a length of about the radius of the pad.
The heating element is working till the soldering tip reaches certain temperature, then the power switches off. When the temperature becomes lower than a certain level the heating element is on again and the soldering tip is being heated. The operation is ensured by the magnetoelectric relay. It is controlled by electronics and a temperature ...
A soldering iron stand keeps the iron away from flammable materials, and often also comes with a cellulose sponge and flux pot for cleaning the tip. Some soldering irons for continuous and professional use come as part of a soldering station, which allows the exact temperature of the tip to be adjusted, kept constant, and sometimes displayed.
Inside a wave soldering machine, showing the wave soldering process Temperature and time graph showing wave soldering solder pot and topside temperatures. Wave soldering is a bulk soldering process used for the manufacturing of printed circuit boards. The circuit board is passed over a pan of molten solder in which a pump produces an upwelling ...
In soldering, a thermal profile is a complex set of time-temperature values for a variety of process dimensions such as slope, soak, TAL, and peak. [8] Solder paste contains a mix of metal, flux, and solvents that aid in the phase change of the paste from semi-solid, to liquid to vapor; and the metal from solid to liquid.

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.
