Challenges of cleaning technology in electronic manufacturing

First of all, everyone should understand that in the manufacturing process of electronic products, circuit board assembly and chip packaging will be corroded by various pollutants in the production process due to complex structures and tiny gaps, such as flux, dust, etc. These pollutants may cause problems such as circuit performance degradation, poor reliability, and signal interference. Therefore, the importance of electronic process cleaning technology is self-evident.

However, there are challenges to achieve the ideal cleaning effect.

The first one is that in the early 1990s, no-clean flux/no-clean solder paste had appeared in the electronics manufacturing industry, and many people believed that electronic components no longer needed to be cleaned.

Another is that as integrated circuits become more and more sophisticated, chip packages are getting smaller and smaller. High reliability and cost reduction have become development trends, and the cleaning process of electronic processes has become arduous and complicated.

In addition, in recent years, many electronic product welding processes have been transformed into lead-free plating and solder alloys, which usually use higher welding process temperatures, and the flux and solder paste formulas used in production are more complex, and the cleaning process is more difficult.

The fourth is that ecological environmental protection and worker safety are increasingly valued. The cleaning agent used in the electronic process must meet the requirements of relevant indicators including VOC, BOD, COD, wastewater treatment, heavy metals, closed circulation, pH value, etc.

With the rapid development of high-precision and high-reliability electronic products, the progress of the economy and society, and the popularization of environmental protection concepts, the development of a new generation of efficient, environmentally friendly, economical, safe and green environmentally friendly cleaning agents has become the mainstream of the cleaning industry.

In the face of many challenges in the cleaning process, water-based cleaning agents stand out due to their flexible formulas and ingredients.

Non-toxic, harmless, safe and environmentally friendly water-based cleaning technology has become a key technology and ideal choice for electronic component cleaning and semiconductor packaging cleaning processes.

As a company with rich experience in water-based cleaning processes, Lijing Chemical has many water-based cleaning products that can meet the difficult technical requirements of electronic component and chip packaging process cleaning. We are committed to breaking the monopoly of foreign manufacturers in the industry and providing strong support for Made in China.
