MTBF is an abbreviation for Mean Time between Failures . MTBF is a measure of how reliable a product is. MTBF is usually given in units of hours, the higher the MTBF, the more reliable the product is.For electronic products, it is commonly assumed that during the useful operating life period the parts have constant failure rates, and part failure rates follow an exponential law of distribution. In this case, the MTBF of the product can be calculated as:
MTBF = 1/(sum of all the part failure rates)
and the probability that the product will work for some time T without failure is given by:
R(T) = exp(-T/MTBF)
Thus, for a product with an MTBF of 250,000 hours, and an operating time of interest of 5 years of 24×7 (43,800 hours):
R = exp(-43800/250000) = 0.839289
which says that there is an 83.9% probability that the product will operate for the 5 years without a failure, or that 83.9% of the units in the field will still be working at the 5 year point. Note: the Reliability calculation assumes replacement upon failure.
The MTBF figure for a product can be derived in various ways:
1) Lab test data
2) Actual field failure data
3) Prediction models (such as Telcordia SR-332 or MIL-HDBK-217).
Telcordia SR-332
Telcordia SR-332 was originally the Bell Laboratories Bell core standard for the reliability prediction of commercial electronic components.
The Telcordia Standard allows reliability predictions to be performed using three methods:
Method I provides predictions based on a Parts Count procedure.
Method II provides predictions based on combining laboratory test data with Parts Count data.
Method III provides predictions based on combining field tracking data with Parts Count data.
All three methods are handled by the Reliability Workbench Prediction Module
MIL-HDBK-217
MIL-HDBK-217 is a US Department of Defense standard for the reliability prediction of electronic components.
MIL-HDBK-217 provides two reliability prediction methods:
• The Parts Count Method. This is a simpler approach for use during the early design phase and requires less information to be entered, for example quality, quantity and environment.
• The Part Stress Method. This is more complex and requires detailed information on temperature conditions and electrical stress. The part stress method is used when the actual hardware and circuits are being designed.

ROHS, the Directive to limit or rather ban the usage of dangerous substances in electrical and electronic equipments manufacturing, was put-forth by the European Union in February 2003. Five years after the launch of RoHS 1, EU has now adopted the new RoHS Directive or RoHS 2, with more rigid rules to put an end to the usage of toxic substances in electrical & electronic products manufacturing industry. However, there are a lot of companies and factories out there, who are not aware of the new RoHS 2 Directive.
According to environmental compliance experts, RoHS 2 Directive will soon create a major impact on electronic industry, and electronic products manufacturing companies. RoHS 2 Directive was initially published in the Official Journal of EU, on July 1st, 2011, and entered in to force on July 21st 2011. According to EU & environmental compliance experts out there, RoHS 2 Directive will replace RoHS 1 on January 3rd, 2013. Hence electronic products manufacturing companies should have a comprehensive idea about the new RoHS Directive rules and regulations
RoHS 2 covers a wide range of products including small & large household appliances, IT & telecommunication, consumer equipments, lighting equipments, electric and electronic tools, and medical devices. But RoHS 2 doesn’t apply to certain products like military equipments, space equipments, equipments which are designed and manufactured to form the part of equipments which are not within the scope, large scale industry tools, large scale fixed installations, various means of transport, non-road mobile machines, active implantable medical devices, and photovoltaic panels. Therefore electronic products manufacturing companies should have a very clear idea about product categories of EU RoHS.
RoHS 1 was brought into force to curb or rather completely ban the usage of 6 major hazardous materials – lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl, and polybrominated diphenyl ethers. According to the reports of EU, these chemicals are highly toxic to humans and extremely harmful to the environment too. RoHS 2 also restricts the usage of all the above mentioned chemicals, with the help of more rigid rules and regulations. Electrical and electronic products companies in the EU are legally bound to obey the rules of EUL legislation. This also applies to the companies that export electrical and electronic products to any of the countries in the EU.
Unawareness of these rules will never be considered as a viable excuse, and therefore it is very important to learn about RoHS , to ensure that your products are fully RoHS compliant. To know about the rules and regulations of EU, companies can contact environmental compliance experts like Enventure Technology Services. We help companies comply to RoHS and its different country flavours, by providing them with a comprehensive audit report about their products, and the materials that they use in the Bills of Materials during product manufacturing. Our experts will also provide environmental compliance consulting services, bill of material assessment, product conversion, and other required solutions to help companies understand and comply with the EU directives.

It’s been almost a century since Democratic Republic of Congo has been consistently exploited for its vast natural resources & mineral wealth. According to the reports submitted before the Congolese Parliament, a few years back, the investigation committee had uncovered some really shocking details about the ongoing illegal exploitation of Congo‘s natural resources, and the illegal trade of Congo’s Conflict Minerals.
Conflict Minerals are mined in conditions of ‘armed conflicts and human rights abuses’. Minerals including casseterite, wolframite, coltan, and gold are widely extracted from Congo, especially from its eastern parts. These minerals are purchased by various multinational electronic companies across the world, and are widely used to manufacture of a variety of electronic devices including mobile phones, laptops, MP3 players, and various other consumer electronic items.
Conflict Minerals Regulation Act aims to put an end to the constant exploitation and atrocities going on in Congo, by closely monitoring the issuers & the companies that use Conflict Minerals. According to this act, both domestic and foreign providers of Conflict Minerals, as well as the companies that use them, are forcefully obliged to comply with Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (Conflicts Minerals Provision), and therefore should disclose the details of the Conflict Minerals that they use, in their annual reports. This public disclosure will highlight the exploitation and trade of minerals from Democratic Republic of Congo and its adjoining countries.
Dodd–Frank Wall Street Reform and Consumer Protection Act was passed by the US Senate on May 20, 2010, and was signed by American President Barack Obama on July 21, 2010.
According to experts, this Act will completely purge the funding of armed groups in Democratic Republic of Congo. Armed groups in and around Congo make millions of dollars every year by selling Conflict Minerals and their derivatives, to various companies across the world.
According to the Conflict Minerals Regulation Act, companies are legally bound to publically disclose whether their products contain conflict minerals or not, while submitting their annual reports. Companies that use Conflict Minerals should file a separate report along with their annual report, stating the steps taken to properly exercise the due diligence on the source and the chain of custody of the conflict minerals, the details of the products which are not “DRC Conflict Free”, the processing facilities, the country of origin of the Conflict Minerals, and the efforts to determine the origin. Such reports would help in getting better transparency and accountability from those companies & issuers who handle Conflict Mineral ores or their derivatives.
