The Restriction of Hazardous Substances Directive is the shorter form for Directive on the restriction of the use of hazardous substances in electrical and electronic equipment, and it was set up in 2003
The RoHS was officially set up in 2006, and was set to be fully enforced and became a binding law in every single one of her member state. The principle of the RoHs strictly restricts with few exceptions the use of various hazardous materials in the production of different electrical as well as electronic device and equipments.
All European Union member countries make their own rules as related to the implementation of RoHS directives, while making sure that it doesn’t conflict with the bodies directives.
While many refer to the RoHS as a lead free directive, the organization basically restricts the use of about ten products namely; Lead, Mercury, Cadmium,Hexavalent Chromium, Polybrominated biphenyls, Polybrominated biphenyl ether, Bis(2 ethylhexyl) phthalate, Butyl benzyl phthalate, Dibutyl phthalate, Diisobutyl phthalate .
The RoHS has been structured to work in such a way that it restricts products that have even a proportion of the restricted or banned substances.
For instance, an electronic device like a microwave or tv could be produced from mostly acceptable materials like screws, case, plastic coverings, which are homogenous materials. but the percentage of the banned materials are more then the product will have failed to pass the directive of the RoHS.
There are lots of restricted substances that are being sold in various markets across the world, they basically contain lead, they include; batteries, metal parts of vehicles and appliances, electrical power chords. Photographic materials and lightening products such as bulbs and lamps.
RoHS is a body dedicated to reducing and eliminating the use of hazardous materials in electronics have moved further to put efforts towards a similarly disturbing issue which lies in electronic waste globally. As new products are bought and put in use, they replace older products thereby leaving the said useless and obsolete. These products eventually turn out to become wastes that become huge problems in affected countries if not recycled.
In spite of all the restrictions imposed by RoHS, there are certain exceptions to them and they are over 70 in number, they expire after 5 to 7 years except of course they are renewed, they are also plans to include other products to the list of restricted products.
Examples of exception to the regulations include; Lead when it’s used as an alloy in metallic, melting temperature solders, lead in solders for servers, garage, and storage array gadget,cadium in solar panels, and so forth.
Research into new alloys and technologies is permitting groups to launch RoHS merchandise that are presently exempt from compliance, e.g. Laptop servers. IBM has announced a RoHS solution for excessive lead solder joints as soon as idea to stay a permanent exemption. The lead-free packaging generation offers cost-efficient advantages in relation to standard bumping approaches, including solder waste discount, use of bulk alloys, faster time-to-market for products and a much lower chemical usage price.
Test and dimension providers, including National Instruments, have additionally started out to provide RoHS-compliant merchandise, despite devices on this category being exempt from the RoHS directive.
