How ICT works, what is ICT

ICT test fixture is the abbreviation of Incircuitest test fixture, which is the first detection and test fixture. It is a standard test equipment that tests the electrical properties and electrical connections of the most advanced components to check for manufacturing defects and defective components. It is mainly used to check the first single component and the open and short circuit of each circuit network, with the characteristics of simple operation, fast and fast, accurate fault location, etc., ICT test fixture can be used for analog device function and digital device logic function test, high fault coverage, for each type of single board need to make a special needle bed, this needle bed is called ICT test fixture in industrial production.

1. General functions of ICT:

In just a few seconds, we can fully detect the parts on the assembled circuit board: resistors, capacitors, inductors, transistors, FETs, LEDs, ordinary diodes, voltage regulators, optical lotuses, ICs and other parts, whether they are operating within the specifications we designed.

It can find out the defects of the process in advance, such as short circuit, open circuit, missing parts, reverse, wrong parts, air welding and other defective problems, and feed back to the improvement of the process.

The above fault or bad information can be printed out by the printer to print the test results, including the fault location, part standard value, and test value, for the reference of maintenance personnel. It can effectively reduce the dependence of personnel on product technology, and there is no need to understand the product line, and there is still the ability to maintain.

4.The production management personnel can analyze the statistics of test defects, and find out the causes of various defects, including human factors, so that they can be solved, improved and corrected, so as to improve the manufacturing and quality capabilities of circuit boards.

It is precisely because of the huge benefits brought by the above functions of ICT to customers that there is a reality that ICT has been widely used today!

ICT Special Features:

Electrolytic Capacitance Polarity Test Technique:

The electrolytic capacitance is reversed, and the missing parts can be measured 100%.

The parallel electrolytic capacitor is reversed, and the missing parts can be measured 100%.

ICT is an abbreviation for testing. ICT is an important part of the production of electronic processing enterprises, and most of the process defects in the production process can be found. At present, most of the more authoritative ICT test instruments in the industry are produced in the United States, such as Agilent3X7X, Spectrum 88xx, etc.

The tests it completes mainly include: internal circuit on-off test 2, process defects or wrong parts, short circuits caused by bad parts. 3. Commonly used to simulate the nominal value test of the original.

The principle of each test is different. However, the principle of analog original test is based on the imaginary short and imaginary disconnection principle of integrated operation amplification circuit, while the digital original test is based on the truth table of digital originals, and the output results of the original are predicted by analyzing the truth table, and the predicted results are compared with the actual test results, if the results are consistent, the original is considered OK, otherwise the test fails.

** Test, ICT, In-circuit Test, is a standard test method to check manufacturing defects and defective components by testing the electrical properties and electrical connections of ** components. It mainly checks the open and short circuit of a single component and each circuit network, and has the characteristics of simple operation, fast and fast, and accurate fault location.

<> ICT is a combination of the prefixes of the three English words information, communication and technology. It is a new concept and a new technical field formed by the integration of information technology and communication technology. At present, ICT is more and more used as a service to customers, which is the combination and integration of IT and CT services, and the communication industry, electronic information industry, Internet, and media industry will be integrated into the scope of ICT.

Fixed network operators such as China Telecom provide one-stop ICT services to customers, including integration services, outsourcing services, professional services, knowledge services, and software development services. ICT services not only provide enterprise customers with solutions for line construction and network architecture, but also reduce the burden on enterprises in setting up applications, system upgrades, O&M, and security.

IT stands for Information Technology and CT stands for Communication Technology. ICT is a new field of technology created by the combination of information technology and communication technology. This technique is widely used in work.

For example, if a large company opens a branch office in a major city across the country, it can hold remote meetings between the branch and the head office using ICT technology.

In layman's terms, ICT is equivalent to a powerful multimeter; The tooling is equivalent to integrating countless multimeter pens together to test the circuit board. The test items are:

Component failure: out-of-tolerance and damage of resistors, capacitors, inductors, diodes, transistors, integrated blocks and other components;

Soldering failure: bridging and missing soldering after soldering through wave soldering or reflow soldering in PCB assembly processing;

Plug (paste) assembly failure: missing plug (paste), plug (paste) reverse, plug (paste) wrong in PCB assembly processing;

Circuit board fault: the opening and closing of the copper foil of the PCB board.

The disadvantage of ICT is that a circuit board must have a corresponding fixture.

ICT Advantages:

Unified hardware platform – easy to invest in.

Unified process – easy to control.

Precise fault location - easy to learn.

Faster – lower maintenance costs.

The only way to catch hidden electronic faults is to improve product quality.

What exactly is ICT testing? Let's listen to the doctor explain it to you.

Well: Are you referring to ICT equipment, instruments or what? Generally speaking, ICT is similar to many multimeter stylus, probes are similar to pen contacts, and the size and resistance of the measured components are used to compare with the value you set

ICT is information and communication technology. ICT (Information and Communication Technology) is the infrastructure and component that enables modern computing. While there is no single universal definition of ICT, the term is generally considered to refer to all the devices, network components, applications, and systems that enable people and organizations (i.e., businesses, non-profits, and criminal enterprises) to be able to do so in the digital world.

ICT, or Information and Communication Technology (ICT), is the product of the increasingly close integration of IT and CT. ICT service business is a comprehensive service business integrating user system and software development and integration, maintenance and consulting services, and leasing business, and communication operators use their rich experience in the field of network and information professional technical services to provide customers with professional IT services, so that customers can focus more on their core business development.

ICT business is an organic combination of integrated services, outsourcing services, disaster recovery services, information exchange, application interaction, collaborative processing and other platform application business services not based on the enterprise information integrated service platform, knowledge services and other IT services and applications for government and enterprise customers, including IT services and application business services such as system professional services and knowledge services.
