According to relevant organizations, in the next five years, the global wearable market will grow substantially. By 2019, the annual global wearable device shipments will reach 148 million units, compared with 33 million units in 2014, compound annual growth. The rate is as high as 35 percent. So, how to seize this development opportunity and what factors need to be paid attention to in the development of wearable devices? What technical support is needed in the future? To this end, the 2015 International Intelligent Wearable Device Safety Technology Summit Forum, hosted by TÃœV SÃœD and co-organized by China Inspection Co., Ltd. and International Wearable Technology Group, was held in Shenzhen to discuss the risks brought by wearable devices and consumers. Problems such as potential safety hazards and the development of relevant safety standards.
Standardization is imminent and will be the driving force of the market
Despite the hot development of the wearable device industry, more and more companies are investing in R&D and production of wearable products. However, there is no unified technical standard in China, so the quality of products in the industry is uneven, and consumers are worried about data security. The problem is not solved.
Mr. Dirk von Wahl, President and CEO of TÃœV SÃœD Greater China
Mr. Dirk von Wahl, President and CEO of TÃœV SÃœD Greater China, said that TÃœV SÃœD is able to offer a range of test solutions for wearable devices with strong and experienced experts who can help throughout the product development cycle. Customers solve quality and safety issues. At the same time, it is also pointed out that China manufacturing is the main force of wearable device manufacturers. TÃœV SÃœD can learn the latest information from the domestic wearable device manufacturers and companies, and prepare for the future participation in the development of wearable device industry standards. Promote the healthy and orderly development of the wearable device industry.
In response to the safety requirements of wearable devices, Mr. Wang Xin, Chairman of China Inspection Co., Ltd. (Hong Kong) pointed out that in recent years, the popularity of smart wearable devices has continued to increase, with mature cloud services and a large number of information technologies to support them. The network environment and rapid development of detection technology to ensure that the performance of the wearable industry is increasingly mature, but does not mean that its development will be smooth and impeccable. Wearable products must also address a range of issues that affect product performance and safety in order to be healthier, more robust, improve human production and lifestyle at a more substantial level, and bring progress and advancement to all areas of human activity. For the wearable industry, it is a huge challenge.
In the formulation of relevant standards, Mr. Wang Tianzhi of the National Standards Committee was also invited to attend the summit, expounding the standardization of China's wearable device industry, including key technical issues in wearables, such as battery technology, sensing technology, and people. Machine switching technology, information security and privacy protection will be paid attention to. The development of standardization will strongly support the development of the wearable device industry, help the upstream and downstream interconnection of the industry chain, in the basic norms, equipment quality standards, data standards, products. The evaluation specifications, product performance requirements, and safety specifications are vigorously laid out in six aspects.
Mr. ChrisTIan Stammel, CEO, International Wearable Technology Group
As a partner of TÃœV SÃœD, Mr. ChrisTIan Stammel, CEO of International Wearable Technology Group, brings the development trend of the international wearable industry and introduces the related issues of why safety and reliability in product design are so important. In view of product size and shape constraints, wearables are more oriented toward functionality and operability than simple and feasible solutions, and wearable devices will be enhanced from energy consumption, materials, sensing, speech recognition, and user interface. And predict that the future of automotive electronics will break out of a new revolution in the wearable device market.
Control impedance PCB
Many customers asked us what information we need for impedence control PCB.Here,there are two types for PCB manufacturer,a is single impedance ,just one trace ,two holes .and b is differential impedance,it always go with 1 pair (two trace with same width and space). For single impedance,you just tell us the trace width one which layer and what value you require .For differential impedance,trace width/space,layers and value. Our experience engineers will calculate following your instruction with Polar software.We may change trace width/space or stackup ,but please do not worry, if any changes,we will send you to approve before proceeding. Generally,the tolerance is 10%,and more accurate is 8% .All impedance boards ,we will test here and report.
