Chip of an entrance MOS (1688 nets cut pursues)

Current, the own capability of each domain chip gets attention fully. The card that the netizen gives out to was published 2010 recently ” Chinese electron industry and other, the current situation of science and technology that electronic industry takes a fancy to a country ” , the article says to apply extensively at our country dynamoelectric bicycleProductionA kind of medium unit price only the low end of two-spot MOS chip ” long-term by forestall of international big plant, homebred and congener product is without competition ability ” .

8 years past, whether does chip of dynamoelectric bicycle MOS count an import badly still? Recently, ” daily economy news ” the reporter undertook one time for thisInvestigation, the high-end product that discovers international big plant is being held reallyThe marketThe mainstream, andThe priceWhen the river rises the boat goes up too, in the meantime, home already had manufacturer implementation is homebred change and commercial application. So, where is the home products outside why be still being used more inside course of study?

InternationalBrandStill take the main aspect, a few homebredBrandAlready business with

MOS, chinese name is effect of insulation bar field to be in charge of, main production manufacturer is centered in Han of Euramerican, day. MOS chip (namely MOS is in charge of) it is to produce yuan of parts of an apparatus or appliance with dynamoelectric bicycle indispensable controller, the basis is normally comfortable match power to differ, controller of individual and electric car should use 6~12 MOS chip.

In 1688 A Libaba approves hairnet to go up, ” daily economy news ” reporter with ” MOS provides electric vehicle ” for key word retrieval, search 858 relevant products in all. These products are main with meaning law semiconductor, Ying Feiling, 10 thousand countries the international brand such as instrument of He Dezhou of semiconductor, celestial being child, flying rainbow is a delegate, The priceFluctuate in 2 yuan more.

And in the reporter with ” homebred MOS provides electric vehicle ” after be key word retrieval, the product measure that the sieve singles out only 22, but paste brand product more again among them. The reporter is found only in searching a result ” the Yi after Xi’an ” for product of normal and homebred brand, and limited company of science and technology of electron of Suzhou Xin Ze Biao is inSaleCard of home made product.

The product that seizes a company reveals a page to show, “The Yi after Xi’an ” namely limited company of science and technology of semiconductor of the Yi after Xi’an (the Yi after Xi’an of the following abbreviation) , public data shows, this company one day Inc. of group of Shui Huatian electron is held secondhand, and this group appears on the market just about the large stockholder of science and technology of company China day. It is one furniture has MOS chip and power source government the power parts of an apparatus such as IC andDesign of analogue integrated circuitThe company of ability of research and development.

” daily economy news ” the reporter discovers after website of bureau of national intellectual property retrieves, the Yi after Xi’an is in electron yuan parts of an apparatus and semiconductor domain already hold is multinomialPatent. The reporter calls the Yi after Xi’an subsequently, in expression want to understand its productSaleAfter the idea of the circumstance by excuse oneself from. Nevertheless, its agent Shenzhen is platinic fine the customer service of semiconductor limited company expresses to the reporter, the product of Yi is after inside the industry already had wide application.

Manufacturer of electric car controller, without limited company of science and technology of stannic city ox personnel of 1688 networks customer service expresses, they had used the MOS chip of the Yi after Xi’an of card of home made product in partial product. But the reporter sees, more controller manufacturer reach trafficker, in liking to introduce a page in the product, emphasize ” MOS of product use entrance is in charge of ” .

Limited company of science and technology of electron of Suzhou Xin Ze Biao, be in its of 1688 its oneself product was offerred in showing a page, can replace the specific model of product of what international big plant. The reporter is contacted with the client’s identity and personnel of its customer service, put forward to buy to be able to replace meaning law semiconductor ” ST75N75 ” the product of model, the MOS chip that produces oneself to just introducing them to the reporter relatively entrance original property is very contiguous, having manufacturer of very much dynamoelectric bike is its client.

A homebred MOS chip (1688 nets cut pursues)

Tearing open parts to sell 5 wools only is cheaper than homebred brand

” daily economy news ” the reporter observes in 1688 nets, the MOS product quoted price of the Yi after Xi’an fluctuates in 1.5 yuan, quoted price of product of other and homebred MOS is centered in 0.5 yuan of ~0.8 yuan. And the reporter is in with buying a capacity the understanding after be being contacted with trafficker of chip of MOS of partial international brand arrives, the ST65N75 model that ST brand former plant produces already stopped money, and originally 5 yuan when 2 yuan unit price has gone up to nowadays many.

Trafficker of partial MOS chip recommends a kind to the client to the utmost the name is ” hit ST ” product. 1688 netsRegisterThe name is ” Shenzhen city is added especially special limited company of science and technology ” businessman introduction, they sell ” ST75N75 ” chip is an entrance, but in homeEnclose, be not former plant product, “But if your demand is not high, can replace former outfit basically… home is very much now be copy former outfit, do not tear open crust to look sure. “

Afore-mentioned businessman customer service say: “If have really,want lot, I can let a factory do not imprint the brand of ST go up. ” 1688RegisterThe name is ” Yong Xinhang of blessing of area of Shenzhen city Baoan sends electronic trading company ” trafficker has ST75N75 product to sell likewise, and quote only 1 yuan. Customer service of the other side call the product in the communication with the reporter tear open parts, but ” be former plant absolutely ” . He still says: “In general we offer a month hundred thousands of… hill of Yangzhou, elder brother if somebody is in,make controller only, that is being used namely tear open parts. “

Because come from more,tear open parts at Shenzhen, the price is the very preponderance that its can sell well. The price that comes to reporter hair with trafficker of 1688 nets MOS is exemple, ST75N75 tears open parts 5 wool money, homebred copy is tastedQualityTop unit price 1.42 yuan, CharacterGeneral want 9 wool money only, standard of list price of calibration plan home made product is lower.

Whether can be homebred MOS chip used at electric car?

” daily economy news ” the relevant researcher that reporter connection pursues circuit research and development in the college at present to, the other side expresses, homebred MOS chip is low-cost, be used to the product research and development of easy loss merely soTestIn the experiment, and bruntPurchaseThe product still comes from international big plant.

And before the customer service of limited company of science and technology of ox of the city that do not have stannum of product of the Yi after expressing to had used Xi’an in controller personnel also says further, they are only at present in small-power controller product use homebred MOS product, be in comfortable the MOS chip that what use in the controller product that distributes high-power electric machinery is the production such as Korea as before.

Believe ministry data according to labour, our country dynamoelectric bicycle accumulative total finished annual 2017 crop thirty-one million one hundred and thirty-one thousand, accumulative total grows 2.3% compared to the same period. Dynamoelectric bicycle advocate business Wu income one hundred and one billion and thirty million yuan, implementation profit total 4.8 billion yuan. Use 5 MOS chip, unit price according to car of every storage battery 2 yuan undertake estimating calculating, our country achieved 300 million yuan in the defray on small MOS chip 2017.

Fang Jing of analyst of industry of electron of the negotiable securities that enrol business says to the reporter, dynamoelectric bicycle belongs to low end with MOS chip product, and be involved scarcely complexPatentCamp, domestic manufacturer already canMake. But as in last few years electric car greets new energy resources high speed develops, the MOS chip domain of electric car class will welcome more intense competition. And because its technology demand is higher, homebred MOS still cannot achieve business to use a requirement, relevant industry still is importing chip of MOS of electric car class in great quantities.
