Discussion on Circuit Board Cleaning Methods in Yantai Circuit Board Processing

When it comes to the most common items nowadays, circuit boards are actually one of them. Although we generally "can't see" them, they exist in all electrical appliances and electronic products in our daily lives and work. With the enhancement of China's technological strength, domestic circuit board processing technology has become increasingly mature. Yantai's circuit board processing industry has also kept pace with domestic development trends and secured a certain market share in the country. Previously, the editor has analyzed and explained: Yantai circuit board processing helps you understand testing and maintenance techniques, and you now have a certain understanding of maintenance. Next, let's discuss an important aspect of daily maintenance—circuit board cleaning, which you can learn about:

Currently, circuit board cleaning primarily employs cleaning agents. The commonly available cleaning agents on the market are essentially chemical industrial cleaning solutions, mainly used for cleaning PCB circuit boards after soldering to remove residual flux and rosin on their surfaces. The specific usage methods are as follows:

1. Manual Brushing: Dip the circuit board to be cleaned in an appropriate amount of solvent. After a short while, use a brush to scrub the areas with rosin and flux on the circuit board. This will accelerate the dissolution of rosin and the removal of flux.

2. Ultrasonic Cleaning: Place the circuit board in a fixture to prevent excessive vibration from the ultrasonic waves from damaging electronic components. Then, place it in an ultrasonic cleaning tank. Finally, determine the ultrasonic frequency and cleaning time before starting the cleaning process.

The above is a summary by Yantai Zhan'ge Electronics Co., Ltd. on circuit board cleaning methods. There are many types of circuit board cleaning agents available on the market, and their primary function is cleaning. The editor advises against purchasing cleaning agents marketed under other names, as their actual effects are mostly unsatisfactory.
