Apple's revenue in China rose 71 percent , surpassing Europe

Apple's revenue in China rose 71 percent, surpassing Europe

Apple on Monday released the 2015 second quarter earnings, reported in Greater China smoothly among Apple's second -largest market, significantly beyond Europe, it is the only revenue qoq rise area.

Greater growth is more than three times that of Europe and the US Pacific market growth. In the first quarter, Apple opened five new stores in China. Analysts predict that Apple will add 40 retail outlets in the country by 2016.

It is estimated that, from a volume perspective the iPhone has become the biggest buyer of Chinese consumers. However, the quarter 's revenue in China is still lower than the Americas region , but significantly beyond Europe, ranking second. 

Apple's revenue for the quarter was $ 1.6823 billion in Greater China, an increase of up to 71 %. Consumption levels rising middle class in China rising to become Apple's consumer electronics force. Apple CEO Tim Cook in the earnings conference call last quarter, said , "We can clear that we believe that China 's future, this is an incredible market ."

On the new Apple Watch conference, Apple even shows a variety of Chinese consumers commonly used applications, such as micro- letters. Many analysts had expected, iPhone sales slowed sharply in the quarter after the US consumer. 

But the iPhone 6 to the Chinese people flock to substantial sales growth in China to make up for the negative impact of slowing sales in other regions brought.

Teach you how to read the hardware schematics

Teach you how to read the hardware schematics

Schematic Elements，

We say that a circuit diagram , also called c ircuit diagram ( schematic ) , is a reflection of an electrical circuit diagram of the connections between the various components of the drawings . Teach you how to read the hardware schematics.

Through the schematic analysis, we can understand the product circuit structure and working principle . Therefore , one of the PCB schematics understand whether qualified engineers measure , but also a necessary basic skills. Teach you how to read the hardware schematics.

So the question becomes , how can we understand it as soon as possible schematics ?

To read schematics, architectural schematics first have a basic understanding of the various components of skilled schematic symbols , and know the schematic drawing law rules .

First of all, to share with you the constituent elements of the circuit diagram .

A complete circuit diagram is constituted by a number of factors . These factors include:

Graphic symbols Text symbols Connection. Text description Devices digit number and parameters, etc.

Let us further illustrated by a diagram :

1.Graphic symbols

Graphic symbols constitute the main body of the schematic . In the figure, for example ,

Wave shape : that resistance

Two short box: represents the capacitance

Continuous semicircular : that beads or inductors ,

Box Shape : that integrated circuits

Between the various elements of the graphic symbol or page using the inter-link connector to link up to form a complete circuit.

PCB strong book to bill ratio February North American

PCB strong book to bill ratio

International Association Connecting Electronics Industries (IPC) released "Statistical PCB industry research report in February in North America " today . The report shows that February sales still sluggish , but orders rose , pushing book to bill ratio higher.

North American PCB industry total shipments , compared with February 2014 , down 1.1% , resulting in YTD shipments fell 1.6% ; compared with the previous month , the chain increased 1.2%.

PCB total order amount , compared with February 2014 , an increase of 5.1% , pushing orders increased 0.9 percent so far this year ; compared with the previous month , a decline of 0.7 %. February 2015 North American PCB industry book to bill ratio up to 1.05.

Data Interpretation

Book to bill ratio , is the ratio of the research project with the participation of IPC sample orders in the past three months, divided by the year's sales , to get. The ratio of more than 1.00 , indicating that the current demand exceeds supply , suggesting the development of the next three to six months, sales growth trend will be in . Ratio of less than 1.00 , it indicates that the current supply is greater than demand .

Year growth rate and growth rate so far this year , for the exploration industry trends instructive. Ring data affected its cyclical and short-term changes in factors need to be treated with caution . Compared with the shipment data, order data changes larger orders shipped between the ratio of change from month to month , is not so important , unless there are significant changes in three consecutive months trend. Reasons for change orders and shipments and understand book to bill ratio of change is equally important.

IPC 's monthly PCB industry statistics , data from a representative in the United States and Canada rigid / flex PCB manufacturers sample companies regularly offer. IPC will publish monthly PCB and PCB book to bill ratio statistics project reports . Monthly statistical report will be released in the last week of the following month.

PCB board EMC automated inspection tool (EMC_CONTROL) development

This article describes the history of Huawei CAD department in EMC research and development. CAD department because of its focus on board-level nature of work more EMC problems , system-level EMC aspects from another department (EMC laboratory ) is responsible , EMC EMC laboratory has a very comprehensive test equipment and hardware platform, EMC research conditions than the hardware aspects of CAD department is good, so how in the development of CAD in the cracks EMC business is worth thinking managers !

EMC (electromagnetic compatibility ) : is required to run does not produce electromagnetic interference can not tolerate any of its environment, the ability of the device or system meets the equipment in its electromagnetic environment. Because the system level EMC (electromagnetic compatibility ) too many factors involved in the simulation , the algorithm is too complex , currently on the market is not mature commercial software for a slightly more complex EMC systems for accurate simulation . EMC treatment in most cases is : EMC engineers based on engineering experience or DESIGN RULE product inspection, corrective or preventive . Although many EDA software can simulate statement EMC, but the software can emulate some of the more simple example EMC , EMC problems for the slightly more complex to deal with , or powerless.

Deal with EMC problems arise dependent on experience in product engineering is relatively high, the real problem through software emulation is rarely found . EMC engineers in many cases will be reviewed in accordance with EMC Checklist (EMC Checklist), this table is generally focused on the experience of the various proposals and compiled a list of "large ", many of the items are checked only for specific products and conditions to be effective , so use it to check for other specific conditions are not suitable product . Before the product launch , engineers will inspect each item according to EMC Checklist corresponding checks to determine whether the product is designed to meet the requirements , when checking the entry of more than a case of missed prone . EMC has a strong professional examination , experience different results when engineers same product with the same EMC Checklist table check may not be the same, because the experience of the engineer can grasp some of the checkpoints , which may be the emergence of a people think this place is going to amend , modify another case of unnecessary people think .
As the board level , package level and IC level EMC design incorporated into the core interconnect technology to develop together with the PI and SI force , which is to improve the status of the interconnect in the company will be quite helpful.

The world's 8 inch wafer competition pattern has changed

The world's 8 inch wafer competition pattern has changed

 

Recently, Yonhap news said, in core international (SMIC) is working with South Korea's largestsemiconductor foundry enterprise -- the eastern Gaoke (Dongbu HiTek) to discuss merger.South Korea Development Bank in charge of matters relating to the sale of the eastern Gaoke(KDB) is the source of the message. According to the bank officials said the message says, the primary stage of negotiations are still, and no exchange relevant price details views. While the eastern Gaoke has not held an open tender, just sign in to seek private contract.The world's 8 inch wafer competition pattern has changed.

The eastern Gaoke is Korea's only existing foundry enterprises, with two 8 inch wafer fab is currently in South Korea, manufacturing the main products include CMOS image sensor, power management IC and digital audio amplifier chip. The eastern Gaoke 2014 sales of $531000000,40% are from the South Korean domestic small and medium sized enterprises.The world's 8 inch wafer competition pattern has changed.

In 2014, the Eastern Group (Dongbu Gruop) the outbreak of financial crisis, the urgent need forindustrial restructuring -- the sale is not a sound business, in order to reduce the toxic assets of the group, and to ensure that the cash flow. This is the sale of fate to fall in the eastern Gaokebody.The world's 8 inch wafer competition pattern has changed.

According to the BusinessKorea report, although the eastern Gaoke in the first half of 2014turned into profit, operating income reached 11000000000 won ($10020000), but there are still800000000000 won ($784000000) of liabilities, which directly leads to the eastern group every year to carry 60000000000 won ($59000000) financial interest cost.

In 2014 August, the group announced plans to sell its eastern Eastern GAOKE 37% stake.According to the assessment, which is about 200000000000 won ($196000000). If the successful sale of the East GAOKE, Eastern group can greatly reduce the cost of debt and interest.

In fact, including Samsung, LG, SK, Korea Hynix Semiconductor enterprises are not localexpress positive intention to purchase, so South Korea Development Bank have already turned their attention to the oversea company. In core international is one of the most active one of thebid.The world's 8 inch wafer competition pattern has changed.
