Halogen free pcb concept:

With the increasing global demand for environmental protection, there is an increasing interest in halogen issues, and the requirements for IEC61249-2-21 for halogen-free manufacturing of circuit boards are defined by the use of electronic welding materials, resins and enhanced performance Of the halogen content of the highest content, halogen-free Following the July 1, 2006 ROHS directive since the implementation of the electronics industry.

Halogen-free is a substance with a halide content of less than 900 ppm and a total of less than 1500 ppm. Halogen is a material that does not meet the halogen-free requirements for halide content.

During the development of printed circuit boards, there are many compounds and elements that are utilized for a variety of purposes. During the early days of PCB development, many toxic compounds were used as either a cost-saving aspect of manufacturing or because of the specific, helpful nature of the element. As humanity develops an increased understanding of the threats that past materials present to life in today’s world, manufacturers are changing methods and finding new materials that don’t pose a threat to individuals working with such creations.Common compounds that are used in PCB developments belong to the family of Halogen elements. Although the composition themselves provide certain benefits to the development of electronics, they are harmful to human life in one way or another.

In regards to “Halogen Content”, we are specifically talking about Chlorine, Fluorine, Bromine, Iodine and Astatine elements which have been commonly used in the production of electronics and plastics such as PVC and . During manufacturing processes, halogens have often been added to components to make them withstand high temperatures and to be flame-retardant, but they are salt-forming compounds which are highly reactive and have low melting points:

•Chlorine: Commonly used as a bleach and disinfectant for cleaning pools, it is also used in electronic components and can cause serious problems if ignited, creating a poisonous gas.•Fluorine: Like chlorine is a gas, but it is more reactive and used in refrigerants, aerosol sprays and rocket fuels (as well as toothpaste).•Iodine: This solid is added to halogen lamps to extend the life of a filament.•Bromine: This fluid is used for flame-proofing, pesticides and dyes.•Astatines: Another solid and somewhat like Iodine, this material has no practical uses right now since it highly unstable and radioactive.
