How Does it Work?
Solder is melted by using heat from an iron associated to a temperature regulator. It is heated up to Heat that around 600 degrees Fahrenheit which then causes it to melt, which then cools creating the soldered joint.
As well as creating strong electrical joints solder can also be removed using a desoldering tool.
Solder is a metal alloy used to create strong permanent bonds; such as copper joining in circuit boards and copper pipe joints. It can also be supplied in two different types and diameters.
What Metals are Used?
Filler metals used in soldering were once lead based, however, owing to regulations, lead-based solders are increasingly replaced with lead free solders, which may consist of antimony, bismuth, brass, copper, indium, tin or silver.
Which Flux Can be Used for Soldering?
Occasionally at the site of the joint, there are impurities such as oil, dirt or oxidation, the flux helps prevent oxidation and can sometimes chemically clean the metal. The flux used is rosin flux which helps the mechanical strength and electrical contact of electrical joints. Sometimes it is also possible to apply a ‘wetting agent’ to reduce the surface tension.
