What does QA department mainly do? QA is the abbreviation of English QUALITY ASSURANCE, and Chinese means quality assurance. Its definition in ISO 8402: 1994 is "all planned and systematic activities implemented in the quality management system, and confirmed as required, so as to provide sufficient trust and show that the entity can meet the quality requirements". Some organizations that implement ISO9000 will set up such departments or posts to be responsible for the quality assurance functions required by ISO9000 standards, and the personnel who hold such jobs are called QA personnel.
What seal does QA Quality Department have? The quality department has a separate seal. IQC inspection has qualified and unqualified seals, and QA also has qualified and unqualified seals. Then IPQC can use labels directly, green (qualified), yellow (to be confirmed) and red (unqualified or scrapped), and labels or seals can be used for special purchases, but they all need the signature of the person in charge.
What department is app? It stands for accelerated parallel processing. Accelerated parallel processing technology. It is a general parallel computing technology introduced by AMD for its GPU. Using this technology, we can give full play to the parallel computing ability of AMD GPU, which can be used to speed up the operation of software or carry out large-scale scientific operations. The predecessor of AMD APP technology is ATI Stream. 20 10 10 with the release of AMD radium HD6800 series graphics cards, ATI brand was officially replaced by AMD. ATI streaming technology has also been upgraded and renamed AMD APP technology. The competitor of AMD APP is nVIDIA CUDA.
For more information about AMD APP accelerated parallel processing technology, please refer to AMD APP entry.
Third party application
The abbreviation of application program, due to the popularity of iPhone smart phones, the current app mostly refers to the application of third-party smart phones. At present, the more famous app stores are the App Store in Apple's iTunes Store, Google Market in Android, and ovi store in Nokia.
Programming application
App is the abbreviation of Application.
In VC++, app is the entrance and exit of the application, where you usually handle some setting information that needs to be read or written when starting and exiting the program, and set some global variables.
Applications in the computer field
The predecessor of app server is middleware, and its history is much longer. As early as 1960s and 1970s, it has been widely used in IBM mainframe system, and it is called TP Monitor. The famous ones are Tuxedo of BEA and CICS of IBM, both of which are executed on the server side of terminal/server mode. Its main function is to separate business logic, conduct distributed computing, automatically manage transactions, resources and fault tolerance. Because of the long development time, the technology is very mature. Middleware was first written in cobol. Now we can occasionally see the old system of cobol's intermediary software, and later the middleware was realized in C++. The famous intermediary software is CICS of IBM and Tuexdo of BEA, which are still widely used in high-end systems, especially banking systems.
However, after the appearance and wide application of object-oriented technology, TP Monitor is not object-oriented, but process-oriented, so the business logic managed by TP Monitor is not as extensible and reusable as the business components in distributed object system, showing great limitations.
However, for PHP, a functional language mainly oriented to procedure calls, TP Monitor can still perfectly support it. With the support of TP Monitor, PHP can also be applied to enterprise environment.
Everything I know is: Linux+Apache+PHP+Tuxedo+Oracle.
Each company has installed servers in several Internet service providers in Shanghai to ensure that it will not be unable to obtain services because of the problems of one Internet service provider. I have seen every server in the Shanghai hotline room. You may not believe it, but in fact, everyone uses their own compatible computers, and the chassis of Century Star is estimated to be not much better than the compatible computers we all bought ourselves.
What department is CCIC? CCIC China Commodity Inspection Company, formerly known as China Import and Export Commodity Inspection Company.
(China Import and Export Corporation; Export commodity inspection company
What department is hm? HM now sells clothing and cosmetics in 24 countries around the world, with more than 50,000 employees. Unusually, H &；; M doesn't have his own factory, and he maintains cooperation with more than 700 independent suppliers in Asia and Europe.
What department is mtl? MTL is the abbreviation of Matrix Template Library, and Chinese is a matrix template library, which belongs to the mathematical function library of scientific and engineering calculation under the mechanism of C++ language and focuses on the direction of linear algebra. Due to the use of a variety of the latest programming techniques, the program execution efficiency is very high, comparable to Fortran. MTL is the abbreviation of material management system, which means "material management system" in Chinese. Its main function is to manage non-quantity and amount basic data such as material classification, coding principle, description, characteristics, storage, establishment date, appearance, image and inventory. Material management system is the basic system of ERP system implementation. MTL, Ferris wheel, Shandou, Yamashita Tomohisa X Ikuta Touma.
What department is SMT? Brief introduction of surface mount technology
Surface mount technology (SMT) is a new generation of electronic assembly technology combining traditional electronic components.
The device is compressed into a device with a volume of only a few tenths, which realizes the high density, high reliability, miniaturization and low cost of electronic product assembly.
And production automation. This miniaturized component is called SMY device (or SMC, chip device). Assemble components for printing.
(or other substrates) is called SMT process. Related assembly devices are called SMT devices.
At present, SMT technology has been widely used in advanced electronic products, especially computer and communication electronic products. International SMD equipment
The output of components is increasing year by year, while the output of traditional components is decreasing year by year, so as time goes on, SMT technology will become more and more popular.
Or:
SMT is the abbreviation of Surface Mounted Technology, and it is the most popular technology and process in the electronic assembly industry at present.
What are the characteristics of SMT?
Electronic products have high assembly density, small volume and light weight. The size and weight of the patch component are only about110 of the traditional plug-in. After SMT, the volume of general electronic products is reduced by 40%~60% and the weight is reduced by 60%~80%.
High reliability and strong anti-vibration ability. The defect rate of solder joints is low.
Good high frequency characteristics. Reduce electromagnetic and radio frequency interference.
It is easy to realize automation and improve production efficiency. Reduce the cost by 30%~50%. Save materials, energy, equipment, manpower, time, etc.
Why use SMT:
Electronic products pursue miniaturization, and the previously used punch plug-ins can no longer be reduced.
Electronic products are more versatile, and the integrated circuits (ic) used have no perforated components, especially large-scale and highly integrated IC, so surface mount components have to be used.
For mass production and automatic production, the factory should produce high-quality products with low cost and high output to meet customer demand and strengthen market competitiveness.
The development of electronic components, integrated circuits (ic) and diversified applications of semiconductor materials.
The revolution of electronic science and technology is imperative to catch up with the international trend.
