In some factories, there will also be cases where the chip cannot be controlled, resulting in serious chip moisture. At this time, the chip has to be baked and dehumidified. Try to avoid high-temperature baking of the chip. Low temperature and low temperature baking below 100 ℃ can be selected. This can avoid the expansion caused by the sudden vaporization of water. This paper collects and arranges some baking materials of components, hoping that this paper can have great reference value to all readers. View >>

In recent years, various electronic devices have emerged one after another, which has brought great convenience to our life. The most widely used component in various electronic equipment should be the resistor. If the resistor is not good, it will directly affect the normal use of the later circuit to a certain extent. Therefore, in order to ensure the normal use of the circuit, we must pay attention to the detection of resistors. Today, let's learn the actual detection method of resistance. View >>

After entering the 21st century, electronic information technology has become the most important technology, and electronic components are the premise of the development of electronic information technology. In order to promote the further development of electronic information technology, it is necessary to improve the reliability of electronic components. The damage of electronic components is generally difficult to be noticed by the observer. In many cases, it needs to be detected and judged with the help of instruments. The following contents are sorted out by the core detection network for your reference. View >>

Chip online burning, which integrates burning and testing, has attracted more and more attention. In fact, burning is a tool for writing data into programmable integrated circuits. Burning is mainly used to write the program (or brush) of the chip, such as single metal tube (embedded) / memory (embedded). Friends who first came into contact with the embedded system were confused about the concept of programming and burning, and thought that the memory must be burned. In fact, the concept of embedded programming and burning is to write programs into memory, which is similar to downloading in daily life. The burning interfaces provided by the burner are used to cooperate with various encapsulated chips. It is recommended that mass-produced customers choose the adapter recommended by the burner manufacturer for chip burning. If the untested adapter is used, there will be poor contact and chip jamming, which will reduce the burning success View >>

Chip is the core of intelligent equipment. Just like the engine of automobile, it plays a key role in the whole product. Therefore, the quality of IC chip plays a very important role in the whole electronic products, and it affects the quality problems of the whole products after they go on the market. For more precise electronic components, the required electronic components (transistors, diodes, resistors, capacitors, inductors and other components) are encapsulated in a tube shell to become the functional micro structure required by the circuit. The more precise the structure is, the more difficult the detection is. In order to ensure whether there are quality problems in IC chips, general enterprises usually detect IC chips. Creative core testing teaches you how to test IC chips View >>

Many components such as resistors, diodes and triodes are made on semiconductor silicon wafer in the form of circuit, and then the pins are connected and encapsulated to form an integrated circuit. How to accurately judge whether the IC in the circuit is in working state? If the judgment is not accurate, it often takes great efforts to replace the new integrated circuit, and the fault still exists. Next, let's look at how to judge the quality of integrated circuit IC chip? View >>

Whether the IC chip pins are qualified is the key to the detection of the molding separation process. To solve this problem, a detection system for chip detection automation in molding separation process is developed by using machine vision and machine automation technology. The experimental test shows that the equipment has high detection accuracy and speed, and can meet the needs of production. The following mainly introduces the IC chip pin judgment sequence, oxidation and function introduction and detection. View >>

With the development of science and technology, there are more and more kinds of electronic components, about 10000 kinds. Its application fields are also very wide, such as thyristor (SCR), inductance coil, transformer, crystal oscillator, earphone, resistance, capacitance, etc. they all use electronic components. In the production process, any product will produce some bad appearance, of course, electronic components are no exception. What aspects does the appearance quality inspection of electronic components include? View >>

Why do components sometimes fail for no reason? The integrated circuit structure follows Moore's law and becomes smaller and smaller. The migration of materials at normal operating temperature increases the risk of device failure in decades. In addition, fatigue caused by magnetostriction can lead to inductive mechanical fatigue, which is a well-known effect. Some types of resistance materials will oxidize slowly in the air, and the oxidation rate will accelerate when the air becomes more humid. View >>

Chip test is generally divided into final test and wafer test from the test object. They refer to the encapsulated chips and the chips that have not been encapsulated. Why is it divided into two paragraphs? In short, because the packaging also has cost, in order to save the cost as much as possible, some tests may be carried out before the chip packaging to eliminate some broken chips. In order to ensure that the factory chips are all OK, the final test, that is, FT test, is the last interception and a necessary link. View >>
