Semiconductor chip IC is very sensitive, so when testing, pay attention not to cause short circuit between pins. Short circuit at any moment can be captured, resulting in burn out of integrated circuit. All the components have formed a whole in structure, which makes the electronic components take a big step towards miniaturization, low power consumption, intelligence and high reliability. The work to be done before testing is to fully understand the working principle of integrated circuits. Be familiar with its internal circuit, main parameters, functions of each outgoing line and its normal voltage. View >>

IC, BGA and other devices are called humidity sensitive devices. Their storage and baking are based on the requirements of IPC standards. Using a certain process, the transistors, resistors, capacitors, inductors and other components and wiring required in a circuit are interconnected, fabricated on a small or several small semiconductor chips or dielectric substrates, and then encapsulated in a tube shell to become a micro structure with the required circuit functions. This structural feature determines that integrated circuit chips will be composed of different materials. The joint of these materials will produce more or less gaps. These gaps may not be visible to the naked eye, but when the integrated circuit chip is placed in the environment, the water in the environment will penetrate into the chip through infiltration. And cause the chip to be damp. View >>

Integrated circuits are divided into commercial devices, industrial devices, automotive industrial devices and military devices. The operating temperature range is also different. Commercial grade devices are 0 ~ + 70 ℃, industrial grade devices are - 40 ~ + 85 ℃, automotive industrial grade devices are - 40 ~ + 125 ℃, and military grade devices are - 55 ~ + 155 ℃. We can judge whether the device can be baked according to the temperature level and baking temperature of the device. This paper has collected and sorted out some data, and we hope this paper can be of great reference value to all readers. View >>

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 >>

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 >>
