Although X-ray is invisible light, it also has the same characteristics as visible light, such as refraction, reflection, diffraction, scattering and penetration. X-ray transmission inspection can provide photos of defects and relevant dimensions at the tested parts of castings. X-ray detection system is widely used in industrial production. Whether it is casting, welding parts, auto parts or food and drug packaging, X-ray detection system is indispensable. View >>

Electromagnetic compatibility (EMC) refers to the ability of equipment or system to operate in accordance with the requirements in its electromagnetic environment without generating unbearable electromagnetic interference to any equipment in its environment. Therefore, EMC includes two requirements: one is that the electromagnetic interference generated by the equipment to the environment during normal operation cannot exceed a certain limit; On the other hand, it means that the appliance has a certain degree of immunity to the electromagnetic interference existing in the environment, that is, electromagnetic sensitivity.

For Chinese enterprises, all electronic and electrical products entering the EU market must pass the ROHS certification to ensure that the ten hazardous substances contained in the products do not exceed the limit standards. Otherwise, they will not be able to export the products to the EU market. Even if they are lucky enough to export, they may face huge fines or even criminal detention once found, and may even cause the entire enterprise to be kicked out of the EU market (except for the exemption mechanism).

Reliability is divided into inherent reliability and service reliability. The inherent reliability of electronic components refers to the reliability of components themselves, which depends on the reliability design of products. Due to reliability problems caused by working conditions, environmental conditions and human factors, defective components can be effectively eliminated through secondary screening of components, so as to avoid the use of defective components and effectively improve the reliability of products. This paper has collected and collated some materials, and I hope that it can be of great reference value to all readers. View >>

Why does the product undergo aging test and what is its purpose? The test standard of aging test can be specified by the customer, and the aging test and inspection can be carried out according to the corresponding national standards without special requirements. The aging test is mainly a high-strength test that simulates various harsh conditions of the product in the actual use process, and reasonably predicts the service life of the product according to the use requirements.

After the PCB is manufactured, there is a shelf life. Beyond this shelf life, the PCB needs to be baked. Otherwise, it is easy to cause the PCB to explode when the PCB is produced on SMT. The baking board can remove the moisture on the PCB circuit board and electronic components. After the PCB circuit board reaches a certain temperature, the flux can better combine with the components and pads, and the welding effect will be greatly improved. The storage time of PCB and the temperature and time of baking PCB are regulated by the industry. Details are as follows: View >>

Damp heat test is also a method to test the corrosion resistance of the coating. The main test process is the damage of saturated water vapor to the coating. Generally, it is conducted simultaneously with the salt spray test. The humid and hot environment generally exists in the whole life cycle of electronic products during transportation, storage and use. Under the influence of the humid and hot environment, the insulating materials and metals in electronic products will absorb water vapor, resulting in product degradation. At the same time, under the joint action of humidity, temperature and electrical stress, it will cause electrochemical reaction and metal corrosion, resulting in the decrease of insulation resistance and increase of leakage of electronic equipment, and in serious cases, arcing, breakdown and circuit damage. The following is a brief analysis of the damp heat test for your reference. View >>

The corrosion gas test is used to determine the corrosion effect of the indoor environment of work or storage on the components, equipment and materials of electrical and electronic products, especially the contact and connecting parts. It is mainly used to determine the adaptability of products to work and storage in the atmospheric environment, especially the contact parts and connections. The main factors affecting corrosion are temperature, humidity, atmospheric corrosive composition, etc. The severity of the experiment depends on the type of corrosive gas and the duration of exposure. This paper collects and collates some data, and hopes to have great reference value for readers. View >>

The reliability test of electronic components is the basis of the reliability of electronic equipment, and is also an integral part of electronic components and small electronic instruments and machines. It is often composed of several parts and can be used in similar products. It often refers to industrial parts such as electrical appliances, radios and instruments, such as capacitors and transistors. There are many kinds of products that need to be tested for reliability. Different enterprises have different requirements for testing. In the case of a large number of electronic components, how to test the components? Let's have a look. View >>
