Open up Tool [International] Group, is a professional design, development, production, brand
Management , Marketing As one Hardware Tools Enterprise, the company's brand EXPLO
IT (Open) has registered more than 60 countries around the world, there is the patented product more than 20 kinds of products are sold in more than 90 countries and regions, the international market more than 20 franchisees. Develop tools to take the world from Yiwu, which is inseparable from its marketing. Develop tools for different marketing model, joined by a brand model. Develop tools to successfully use this model to
Hardware Tool industry. Develop tools [international] Group General Manager Mr. Wu Xianfa that initially the company's marketing model is simple, the guest to Yiwu, the brand promotion, with quality and cheap to guide customers to place orders from abroad, with the the company's development, the gradual expansion of the scale, some of the old models no longer meet the needs of the development, through field visits found that South America, Africa, hardware no manufacturing capacity, these countries are Germany, hardware tools of foreign enterprises of the brand, OEM in China, sent to more countries
Sell , Then the model is the serialization of products, thousands of varieties of hardware and tools, unified brand, unified package, uniform color. The high price of such a tool, not aesthetics, uniformity. Guo Act as if Columbus discovered the New World as ecstasy, this time Mr. Wu Xianfa bold enabled the brand to join the marketing model, in 2007 the company started using the brand to join the marketing model, first in Spain, Portugal, try to use, through use of found this pattern very the need for the development of foreign markets, it has been in use until now.
About how to do the brand to join? Develop tools to [international] Group General Manager Mr. Wu Xianfa that requires two conditions to join the first one is of most importance to develop tools to join the business character,
Thoroughly understand the business by joining the character, if character not,
Even if another distribution network is also hard to become a franchisee to develop tools. Second
Hardware tool industry must be engaged, young motivated, and have some basic sales network. Franchisee is divided into four,
As one of the franchisees need to have their own brands, OEM production in China. Two of our members is to help one of the franchisees sellers, requiring two franchisee must have the following three franchisees, four joined the business, generally four franchisees to directly face the end consumer. In foreign markets to develop tools to [international] groups are generally looking for two franchisees, of course, it must have the following three levels, four of the sales network. If the end-consumer product problems, straight to four franchisees can, and so convenient for consumers. This brand joins the biggest advantages is that there is no joining fee. However, in order to ensure sales, develop tools to potential buyers, the amount of sales made per month requirement.
Develop tools [international] brands to join the Group model has three stages, the first stage is the growth stage, the brand joined the model allows to develop tools for rapid development can shorten the growth period; second stage is the correction period. Of course in the development process will encounter this problem, such models have been the perfect model is the brand joined the amendment period. The third stage is the ideological implantation, which is a highest level of the development period.
Implantation thought about life, about human values, on the society. Shows the three stages of opening tools to this mode of operation of the gradual maturation, not simply in terms of profits to develop tools for the purpose, more attention is the society. In fact, at this stage to open up has been toward the development of the 2008 earthquake, to develop tools to donate life-saving tool in the third stage is a good explanation.

Power/Ground Inductance in PCBs?
I work in PCB mfg, and a customer uses a particular footprint for a BGA device, and I'd like a layman's explanation of what they are doing. Instead of the standard "dogbone" configuration, where a straight trace connects the via pad to BGA attachment pad, they use dual arced connections (the arch is for better soldermask adhesion) in order to lower inductance for power and ground connections. Can anyone explain this in common terms?
Thanks Contramundi....can you explain at all how this change lowers inductance?
Lowering the inductance on a BGA improves the noise immunity of the device & allows for greater speeds within the device.
Higher inductances does the opposite & manifests itself in noise artifacts such as "ground bounce", and "cross-coupling", and reflective noise".
Signals within the BGA require a good low inductance reference power plane(Power pins) & a reference return (Ground) in order to generate high speed signals without noise artifacts. Any discontinuites in the signals with respect to the reference power & ground planes; such as, any added inductance can turn a text book signal into a signal that is very noisy.
The faster the device, and the more pins the BGA has switching the more important lowering inductance becomes.
In fact, with the high speeds that many parts are capable today would NOT be able to work in older package styles like DIPs and and gull-winged pin devices as the inductance present in the actual pin leads themselves are sufficient to add all kinds of noise artifacts on the signals. Hence, the introduction of BGA which dont' have pin leads and have small traces between BGA pin & die.
This is why the distance between the BGA pin and the PCB card becomes increasingly important as devices get faster and contain hundreds of pins. Even subtle changes in the trace geometry (dog-bone vs straight trace vs arcs) can affect inductance.
I hope this helps
