What Is the Relationship Between ICT and Economic Development?

Online tester in circuit tester, referred to as ICT, is an automatic online tester. It is a test equipment produced by the printed circuit board assembly (PCBA) necessary for modern electronics companies.

ICT online test

Right!

1. ICT has a wide range of uses, high measurement accuracy, and clear indication of detected problems. It is a standard test method, and it is very easy for even ordinary workers with electronic technology to deal with problematic PCBA. The use of ICT can greatly improve production efficiency and reduce production costs.

2. ICT Test is mainly performed by contacting test probes with test points from the PCB layout.

The ICT test equipment manufacturer is Agilent, others

Q: What is ICT? A: ICT (In-Circuit Test System), commonly used in Chinese as an online tester, is mainly used for testing of assembled circuit boards (PCBA). "Online" here is a literal translation of "In-Circuit", which mainly refers to components on the line. On-line testing is a test technology that does not break the circuit and does not remove the component pins. "Online" reflects that ICT focuses on detecting circuit board assembly problems by testing components on the line or short-circuit status. Q: What components can be measured by the basic functions of ICT? A: Open, short circuit, resistance, capacitance, inductance, diode, IC protection diode test, etc. Q: Why use ICT? A: According to the statistics of the circuit board assembly industry, assembly defects are mainly reflected in welding open circuit, short circuit, offset, missing parts, etc., accounting for more than 90%, as shown in the figure below. Therefore, the principle of online testing technology application is to be able to quickly detect Faulty components or assembly defects, and can accurately locate defects and defect classification. Q: Can ICT be considered as a multimeter? A: ICT can be regarded as an automatic advanced multimeter, and because it has the function of circuit isolation, it can accurately measure the actual value of each component in the circuit. Q: What are the functional differences between ICT and general electricity meters? A: The meter is used to measure a single part. In addition to ICT, which can measure a single part, it can also measure the parts on the solid board through a needle bed. But there are many loops on the real board, it is easy to divide the signal source with current and voltage, so it is often necessary to add the "Guarding" function to make the measurement accurate. Q: What is the relationship between ICT and AOI? A: ICT is mainly performed by electrical measurement methods, while AOI is performed by optical image processing technology. Both have their own strengths and complement each other. In terms of process arrangements, AOI is generally followed by ICT.
