| Interpretation of Chinese RoHS, the green design in the end | | News source: Reads:8473 AddTime:2011-4-18 10:02:09 Collects this page |
| Environmental pollution has become the problems facing humanity, so green, green design will be the future of electronic product design theme! With China’s" electronic information products management of pollution control measures" or " China RoHS" implemented shortly, Electronic Engineering Times interviewed Premier Farnell product market strategy and director of British electronic components distributors association ( AFDEC ) RoHS Development Group Chairman Gary Nevison, asked him to introduce China RoHS features and implementation situation, the hope of China’s electronic manufacturing and design engineers to provide reference.
China RoHS VS. EU RoHS
Nevison pointed out: " China RoHS applied in China’s sales of products (not including Chinese export products ), the EU RoHS, China RoHS has some special stipulations, this means that compliance with the EU RoHS does not necessarily correspond to the China RoHS." Specific analysis, these special provisions can be roughly divided into 5 categories:
1, Chinese RoHS broader product range. Electronic information products ( EIPs ), refers to the use of electronic information technology for manufacturing electronic radar products, electronic communication products, radio and television products, computer products, home electronics products, electronic measuring instrument products, electronic products, electronic components, electronic application products, electronic material products and its accessories. Note that, the EU is not included in the electronic measuring instrument products, China RoHS have been incorporated into the scope of jurisdiction. But Nevison also revealed that, in 2012 the EU will be incorporated into the jurisdiction of this kind of product. But China is not the white home appliance is included, but it will be part of RoHS play a significant role in the hand.
2, Chinese RoHS with key product catalogue. Includes 6 kinds of restricted substances, testing and CCC certification, products will be included in the" directory". From the beginning of March 1st, the directory will be reviewed once a year, the relevant departments will collect the various vendors feedback, the introduction of further requirements, the current directory covered products has not been identified. Nevison thinks, China RoHS in the invitation to participate in the feedback, than the European Union to be flexible advanced.
3, China RoHS product effective date will be phased in, with the catalog adjustment, there will be more detailed schedule.
4, Mark, harmful, recyclable products will have detailed provisions, and asked manufacturers in product on the label.
5, Product testing and certification. Only by the Chinese government audit of China to carry out product testing laboratory. In Europe, Japan or the United States were test results are not recognized. At present, the Chinese government has approved only 18 such laboratory.
Strategies of green design
The majority of engineers, in the design link," green times " coming will bring challenge. With lead-free solder materials, ease of use, reliability is not high enough, a solid interface made the design and production of chaos. In addition, due to the effects of RoHS, manufacturers may replace the previously used components, then, replaced with the new device to be in the same power conditions or replacing the higher power consuming devices? This is also the majority of the design engineer must consider factors.
Nevison says, European Engineer in overcoming the difficulties of using a" with " converse thinking, first uses a lead-free solder production gives a product, and then a comprehensive inspection of lead-free solder in all aspects of product performance and reliability, and originally used the traditional solder product comparison, find out the unsatisfactory, think of approach from the angle of design to improve. In fact, this approach to engineer has put forward higher requirements, the enterprise operation risks associated with it, and Nevison added in PCB board design, this method is not very applicable.
However, the majority of China’s electronic designers, this way of thinking is a new attempt. How to use design wisdom to make the objective conditions caused by inadequate? How to develop the thinking to the upcoming" green design era"? This is our engineer friends because of the question. The word Nevison also pointed out, green design should be meet the requirements of the" RoHS", but also should be more in-depth connotation. The flammable material specification and a series of other than RoHS content will reflect the more and more widespread influence, therefore to be on the" green design" has a more profound understanding of.
In view of Sony
In 2001, with about one million PS2 cargo ship by the Holland customs seizure, the reason is the cable accessories of cadmium in serious incidents. Although it has not yet issued RoHS, but Holland’s regulations have given SONY a big lesson. For China ’s relevant departments, can draw lessons from European Union RoHS implementation experience, will be very important.
Nevison said, the EU countries in the law enforcement have different standards, according to the RoHS implementation, most of them are mainly consultation and guidance. Since the entry into force, manufacturers are actually 12-18 buffer time of a month can improve the product design process. As AFDEC RoHS Development Group Chairman, Nevison had visited a number of manufacturers, commonly found on their RoHS understanding is more ambiguous, many manufacturers don’t even know what products are also provided in the RoHS range.
Nevison believes that, to take a unified standard law enforcement, supplemented by more laws and regulations with respect to the support, will be implemented on RoHS effect has very big stimulative effect. In March 1st China’s RoHS is about to carry out, the relevant departments will take what kind of attitude? We rub one’s eyes and wait.
Green standard, world without end
For electronic products environmental protection measures and standard for future development, Nevison said, the EU will introduce more relevant standards and guidance documents. As in the chemical materials, energy, battery, may have further refinement. But all kinds of standards and guidance documents are mutual influence, work together so as to promote the implementation of the RoHS standard. He thinks, at present, RoHS and WEEE complexes can basically meet the most related products, comply with the needs of China, but the second half of the year catalog published may bring the new inspiration and challenges, then the relevant regulations will also continue to improve the development of.
As chairman of the AFDEC Nevison in Europe, and led the team that is currently actively in Europe RoHS held meetings, invite related manufacturers for RoHS put forward views and suggestions. AFDEC RoHS development group in the authentication mode, will actively cooperate with bar code. Europe also very concerned about the progress of Chinese RoHS, the need for export products to the Chinese company, AFDEC also actively in Europe for Chinese RoHS promotion and introduction.
Gary Nevison is EE website" RoHS instruction in the era of green design strategy " seminar, welcomed the overwhelming majority of engineers and professionals and he actively exchange.
