Lead Tin Soldering
Are you interested in lead soldering from the supplier company AvecGlob? Here you will find the necessary information on this topic.
Application area
Tin soldering («soft soldering») is a widely used technology in the electronics industry for connecting electronic components to printed circuit boards. Traditionally, the solder was an alloy of lead and tin, usually containing about 40% lead. It is well known that lead is a highly toxic metal, potentially causing a wide range of harmful effects.
The use of lead solders is prohibited in Europe for most purposes from 1 July 2006 in accordance with the EU Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment. However, there are still some applications that allow the use of solders based on lead.
Dangers of the soldering process
Where lead is used in the composition of solders, the risk of poisoning is usually very low. The reason is that soldering is usually carried out at a temperature of about 380 ° C, and a significant release of lead develops only at temperatures above 450 ° C. Thus, inhalation exposure is usually insignificant. However, when soldering lead with tin, small particles of solder can be ejected. Therefore, it is important to take appropriate precautions to minimize these risks. It is believed that with well-controlled soldering processes, lead exposure will be minimal, especially since the average lead concentrations are less than 2% of the maximum permissible concentrations of the metal.
Supplier — AvekGlob Company — offers various types of products from tin of domestic and foreign production, which meets the requirements of standards. The products are offered at affordable prices from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.
Other problems and risks when soldering lead with tin
The real problem with soldering lead is the smoke created by the flux. Fluxes usually contain rosin, which is made from pine resin. Flux is necessary to prevent oxidation of components, remove contaminants from the surface of soldered parts and reduce the surface tension of molten solder. When heated during lead soldering, the flux evaporates and condenses into small particles. They form smoke, which is usually well marked. The consequence of thermal decomposition of rosin is also the appearance of irritating airways of gases.
Protective equipment for soldering lead with tin
Lead soldering using rosin is one of the main causes of asthma. Smoke is formed at temperatures above 180 ° C, which is noticeably well below the temperatures associated with lead soldering. The higher the temperature, the more smoke is created. Lead-free solder, as a rule, has higher melting points than traditional lead-tin.
