Once a company made a statistics to classify the causes of product quality problems. It was found that there are four parts: design, incoming materials, manufacturing process (production) and storage and transportation, accounting for 25%, 50%, 20% and 1 ~ 5% respectively. The problem of incoming materials accounts for 50%, so we come to the conclusion that incoming material inspection is very important. Similarly, in order to ensure the PCB substrates used in the production of SMT production line, these incoming materials must be tested before being put into production to determine whether they meet the production standards. Incoming material inspection is generally carried out by visual inspection in actual production. View >>

What is performance testing? Performance test is to test various performance indexes of the system by simulating a variety of normal, peak and abnormal load conditions through automatic test tools. Both load test and stress test belong to performance test, which can be carried out in combination. Through the load test, the system performance under various workload is determined. The goal is to test the changes of various performance indexes of the system when the load gradually increases. Stress testing is a test to obtain the maximum service level that the system can provide by determining the bottleneck or unacceptable performance point of a system. View >>

Now China's national economic level is rising, and more and more people begin to pay attention to the third-party testing institutions. In this environment, many such institutions also begin to appear gradually. For the rapidly developing testing market, there are still many unsolved or urgent problems on the road of development and innovation. How to choose a regular CNAs testing laboratory? We can make decisions from the following aspects. View >>

Put the electronic components together with something like a belt. Reel the tape on a disc. This is IC braiding. IC, that is, integrated circuit, uses semiconductor manufacturing process to make many transistors, resistors, capacitors and other components on a small monocrystalline silicon chip, and combine the components into a complete electronic circuit according to the method of multi-layer wiring or tunnel wiring. In the circuit, it is represented by the letter "IC" (also with the word symbol "n", etc.). View >>

With the emergence of new technologies, coupled with high profits and low risks, IC chip counterfeit products have become more complex and rampant. When there is a shortage of components, in order to ensure the uninterrupted supply of components, many companies may also look for unauthorized informal sources, but it exacerbates the existing problem of component counterfeiting. Nowadays, the proliferation of counterfeit electronic components has become a major pain point in the component industry. How to distinguish whether the purchased components are counterfeit through appearance? How to identify the authenticity of components? View >>

Reliability test refers to measuring and verifying the reliability of products through tests. The research finds out the weak links of products under the condition of limited samples, time and use cost. Reliability test is the general name of various tests carried out to understand, evaluate, analyze and improve the reliability of products. The test to measure, verify or improve product reliability is called reliability test. It is an important link of product reliability. View >>

Single chip microcomputer burning, also known as single chip microcomputer program download and burning, is essentially a process in which the single chip microcomputer and PC transmit the compiled program to the single chip microcomputer through the interface specified by the chip manufacturer according to the programming protocol specified by the chip manufacturer, and the single chip microcomputer stores the data in its own memory. In embedded systems, it is often necessary to burn code or data to MCU on-chip flash or off-chip nor flash, NAND flash, SPI flash, etc. What is the burning principle of single chip microcomputer? Which method is the best for the product? Here are several chip burning methods. View >>
