July 1, the formal implementation of the EU RoHS directive, which marks the era of global lead-free electronics has come. Some experts even said that the EU RoHS directive is actually lead-free directive, as in the provision of six kinds of hazardous substances in the amount of lead in only the largest, known as the electronic industry, food, shows that lead-free electronic products can be able to across the EU RoHS directive critical threshold. Although China's household electrical appliance manufacturers have claimed to have achieved lead-free production, but experts have said the business information is incomplete, inaccurate, because lead-free is a systematic, not only is the product lead-free components, as well as welding process and process, not a word about all aspects of the constraints can be done.
Lead-free force costs by 20%
In the EU RoHS directive, the experts pointed out that the most critical is how to achieve lead-free, lead-free solder and flux of which is the electronics interconnection technology based materials, the field of electronic industry, "food substances", belonging to the middle of supporting products.
Lead-free solder before the tin alloy as solder materials have been used for thousands of years of history, which lead content of about 37%. In recent decades, with the increase in world output of electronics products, the annual production of solder on the rise every year. Taiwan for instance, in 2005 China's annual output of 10 tons solder than the nearly 18% in 2004, is expected to reach 15 million tons this year, market demand, annual growth rate of 15% -20%.
Is such an important accessory products, the EU RoHS directive can not be made of lead content of more than 1000 PPM, the former lead content in the alloy in a ratio of 37%, but then the ratio should not exceed one-thousandth. The country has also introduced earlier this year, China's RoHS directive, that is, "Electronic Information Products Pollution Control Regulations", is also clear that the lead content of six kinds of hazardous substances.
The introduction of restrictions on law-related, no doubt so that domestic manufacturers and related lead-free solder electronics manufacturers have recognized the importance of lead-free, but according to Beijing Jin Electronic Materials Co., Ltd. of Dong Jingui Chairman introduced this year, despite the solder demand more than ten million tons, but the lead-free solder is only 45 million tons of output this year. Having said that, because the cost of lead-free solder than the average increase of 20% and therefore the lead-free solder Despite low production, but the gap between supply and demand is not great.
Interview some of the home appliances business, says that the current lead-free solder prior to purchase to meet the export requirements and domestic market products may slow a slow start, after all, "Electronic Information Products Pollution Control and Management Measures" to wait until next year, was first implemented in March.
Standards in order to solve the problem?
While with the knowledge about the development of our lead-free solder and developed rapidly, according to incomplete statistics, claimed that companies can produce lead-free solder in the 23 100 or so, but so many businesses, whether or not a unified technology standards to regulate and guide the work of lead-free solder?
It is understood that, in order to support the "Electronic Information Products Pollution Control and Management Measures" of the implementation of Ministry of Electronics Standardization Institute has made "lead-free solder systems engineering research" project, jointly lead-free solder R & D, production, use vendors conduct lead-free solder of the industrialization and standardization.
Lead-free solder to participate in the relevant standard-setting Mend chief engineer in the "China Electronics News" that reporters on the development of standards related to lead-free solders have been imminent, will not speak of the EU RoHS Directive has been implemented, China's "Electronic Information Products Pollution Control Regulations, "Although only be implemented next year in March, but we must see the transformation of lead-free solders will be a result of systems engineering, not only solder in need of rehabilitation, as well as welding process and the process also needs reform, such as Wu Qian of welding high melting point melting point than usual, at least 35 degrees, if not transformation, affect the product's overall production.
There are also lead-free flux and supporting product development, etc., related to upstream, downstream, machine and other enterprises, to implement very long, certainly not 12 individual companies we have achieved such a lead-free production and management Simple.
A machine of anonymity says that the responsible person, the international, national lead of Qushi been unstoppable, Dan Popularization of machine companies lead the biggest problems in products is extensive, a total of 10,000 kinds of uses Ji components, suppliers of these components require a longer lead-free process.
Tens of thousands of lead-free devices with code conversion and certification work has been to the certification, materials, supporting, planning, purchasing, inventory, production, and technology and so great pressure. This complex situation, if there is no strong standards as a support, then the situation is really unthinkable.
To break through bottlenecks in the development of patent
We attach importance to lead-free technologies and standards, perhaps overlooked the lead-free intellectual property rights issues. Because lead-free electronic products has become an inevitable trend of world development, so over the past decade the development and application of lead-free solders have national attention. According to the U.S. Patent and Trademark Office and Japan Patent Office database to search information, lead-free solders have been more than 300 kinds of patents, which only released in Japan on nearly 200 kinds of patents, covering almost all the binary and ternary alloy consisting of elements Lead-free solder.
Mend said the situation means that if we could not have independent intellectual property rights developed lead-free solder, we lead the process in the future can only be controlled by others, not only technically, but also a further expenditure of patent fees.
In this case, our related companies have been early research and development in this area, and a breakthrough. In Beijing, Jin Electronic Materials Co., Ltd., for example, their lead-free solder alloy on the use of multiple approaches, and joined the rare earth elements, not only to ensure reliable welding degree, and a breakthrough in anti-oxidation, for which they have applied for a patent.
Taking into account the cost of lead-free solders, many companies have expressed willingness to use our proprietary lead-free solder, the reporter learned from the side, many manufacturers will be lead-free solders in recent years to expand production scale, as its market very large profit margins, according to experts, 1,000 tons of lead-free solder is about 100 million yuan in output value.
