What are EMC's main tests? EMC electromagnetic compatibility test standard

Date:2022-08-31 17:17:00

EMC test is also called electromagnetic compatibility (EMC). The full name is electro magnetic compatibility, which refers to the comprehensive evaluation of the electromagnetic interference (EMI) and anti-interference capability (EMS) of electronic products. It is one of the important indicators of product quality. The measurement of electromagnetic compatibility consists of test sites and test instruments. The purpose of EMC test is to detect the impact of electromagnetic radiation generated by electrical products on human body, public power grid and other normal electrical products. View >>

Which products need ROHS test certification? Do electronic devices need ROHS certification?

Date:2022-08-30 16:26:07

The laws, regulations and law enforcement established by various countries for the safety and environmental protection characteristics of electronic and electrical products have become increasingly strict. At the same time, some emerging markets have also moved closer to the European and American markets in terms of corresponding legislation. As the first step of environmental protection in the electronic and electrical industry, ROHS has become the basic entry threshold for electronic and electrical products to enter the global market. ROHS test is required in the EU market. RoHS aims to reduce such substances in order to create a safer environment for people handling such products. The main purpose of using RoHS is to prevent the use of harmful substances in the manufacture of electrical equipment. View >>

What are the precautions in the power supply design process?

Date:2022-08-30 16:23:37

With the increasingly extensive and diversified applications in the industry, the power supply products also continue to develop in the direction of high frequency, high efficiency, high density, low voltage, large current and diversification. With the rapid development trend, the PCB design of power products is facing greater challenges, mainly including power conversion efficiency, thermal analysis, power plane integrity and EMI (electromagnetic interference). At the same time, the packaging structure and external dimensions of power products are increasingly standardized to meet the requirements of the global integrated market. View >>

How to do the material test? What are the contents of metal material testing?

Date:2022-08-25 15:57:12

The nominal properties of general materials are measured under certain conditions, but some materials, especially the treated materials, may not reach such properties. Therefore, the properties of materials are very volatile and greatly affected by the treatment conditions, which is the reliability of materials. In order to help you understand in depth, this paper will summarize the relevant knowledge of metal material testing. If you are interested in what this article is about to cover, read on. View >>

What are the main test items of reliability environmental test?

Date:2022-08-25 15:55:14

The test site for environmental test shall be widely representative, capable of carrying out as many test items as possible, and shall be as close as possible to the possible operational environment in the future. However, the environmental test site is often different from the real use environment. When selecting the simulation test items, the use requirements of the items to be tested shall be specifically analyzed. The selected test items shall not only represent the main use environment, but also accelerate the test speed and save money. This paper has collected and collated some materials, and I hope that it can be of great reference value to all readers. View >>

How to solder small electronic components? What are the welding sequences of components?

Date:2022-08-23 18:11:42

In electronic manufacturing, the connection of components needs to be welded. The commonly used welding methods of electronic components mainly include manual welding and automatic welding. The quality of welding has a great impact on the quality of manufacturing. Suitable soldering tin shall be used for welding small components with electric soldering iron, and low melting spot welding tin wire used for welding electronic components shall be selected. Before using the electric soldering iron, tin should be applied. The specific method is: heat the electric soldering iron, apply the flux when the solder can be melted, and then apply the solder evenly on the soldering iron head to make the soldering iron head eat a layer of tin evenly.

Quality certification standard for reliability testing electronic products

Date:2022-08-22 18:32:09

What are the reliability test standards for electronic products? The number of electronic products is constantly increasing, and the quality of products will be affected by different factors in the production process. The reliability test standard is to understand whether the normal use of products will be affected by different climatic and mechanical environments encountered by electronic products in the production and application process. Through the reliability test, the reliability characteristic quantity of electronic products when they are working or stored under various environmental conditions can be determined to provide useful data for use, production and design; It can also expose the problems existing in the design, raw materials and process flow of the product.
