Under the tide of core shortage, the hottest information in the IC industry every month is about shortage and price rise, and the 11th month of 2021 is no exception. In that month, the market shortage, price rise and delivery period extension continued, but the decline of the two major memories continued, resulting in the establishment of "long and short materials" in the market, which will have a new impact on the market.

Quality is the life of an enterprise. Electronic components are the basis of enterprise products. Without highly reliable components, it is impossible to produce "high, precision and sharp" products. The quality and reliability of electronic components is related to the reputation and development of a high-tech enterprise. Therefore, any high-tech enterprise must attach great importance to the quality and system of purchased electronic components, and take practical measures to improve the quality and reliability of purchased products.

Lead containing technology has a development history of more than 100 years. After the research of a large number of lead containing technology experts, it has good welding reliability and stability and mature production technology, which mainly depends on the characteristics of lead containing solder alloy. Lead solder alloy has low melting point, low welding temperature and less thermal damage to electronic products; Lead solder alloy has small wetting angle and good weldability, and the possibility of "false welding" of product solder joint is small; The solder alloy has good toughness, and the vibration resistance of the formed solder joint is better than that of lead-free solder joint. The melting point temperature of alternative alloys is higher than that of existing tin lead alloys. For example, according to the "tin silver copper" alloy which is more likely to be widely accepted in the industry, the starting melting point is 217 ℃, which will cause a process window in the welding process View >>

Most semiconductor devices usually indicate that they need to be used at a certain temperature level, such as "commercial" temperature level (0 ℃ ~ 70 ℃) or "industrial" temperature level (- 40 ℃ ~ + 85 ℃). These two types of temperature levels can basically meet the needs of semiconductor customers who dominate the computer industry, telecommunications industry and consumer electronics industry.

Welding is a process in which the material of the workpiece to be welded (the same or different) is heated, pressurized or both, and whether to use filler materials is selected to make the material of the workpiece achieve the combination between atoms and form a permanent connection. Solder is an essential material for the welding electronics industry. The main solder materials include solder wire, solder strip, etc. What are the basic requirements of these solder materials for solder joints? Let's introduce them to you. View >>

Failure analysis is a new developing subject. The common technical means of failure analysis include appearance inspection, nondestructive testing, thermal analysis, electrical performance testing, dyeing and penetrant testing. It usually simulates and reproduces the failure phenomenon according to the failure mode and phenomenon, finds out the failure cause and finds out the failure mechanism through analysis and verification. It has important practical significance for improving product quality, technology development, process improvement, product maintenance and arbitration of failure accidents. View >>

Chip is the most basic semiconductor material for IC production. The quality of chip determines the quality of IC finished products. The chip size detection system detects the position and size of each part of the chip. Before processing the chip, it is very important to strictly detect the appearance and size of the chip, which is conducive to the subsequent processing and improve the chip processing efficiency. After the chip size detection system is simply set, it can automatically detect and calculate. In case of abnormality, it can prompt the alarm or control the machine to stop. Ng signal can be output after detecting the workpiece that does not meet the requirements. View >>
