Tips for cleaning four PCB circuit boards

PCB circuit boards are widely used in China, and pollutants are generated during the manufacturing process of printed circuit boards, including residues of flux and adhesive and other pollutants in the manufacturing process such as dust and debris. If the PCB board cannot effectively guarantee the clean surface, resistance and leakage will cause the PCB circuit board to fail, thereby affecting the service life of the product. Therefore, cleaning the PCB circuit board is an important step in the manufacturing process. The following are four cleaning tips for PCB circuit boards organized by the editor!

Semi-aqueous cleaning mainly uses organic solvents and deionized water, plus a certain amount of active agent, a cleaning agent composed of additives. This cleaning is between solvent cleaning and water cleaning. These cleaners are organic solvents, flammable solvents, high flash point, low toxicity, safe to use, but must be rinsed with water and then dried.

Water purification technology is the development direction of clean technology in the future, and it is necessary to establish pure water sources and discharge water treatment workshops. Using water as the cleaning medium, surfactants, additives, corrosion inhibitors and chelating agents are added to the water to form a series of water-based cleaning agents. Can remove water solvents and non-polar contaminants.

Used in the soldering process without clean flux or clean solder paste, after soldering directly into the next process for cleaning, no longer free cleaning technology is currently the most commonly used alternative technology, especially mobile communication products are basically one-time use Method to replace ODS. Solvent cleaning is mainly used for solvents to dissolve and remove contaminants. Solvent cleaning requires simple equipment due to its fast volatilization and strong solubility.

The above four cleaning technologies can achieve a certain cleaning effect, but how to clean the PCB board quickly and effectively? The application of ultrasonic cleaning machine can be solved. It uses UHF to transform into kinetic energy in the liquid medium to produce a cavitation effect, forming countless tiny bubbles, and then hit the surface of the object to peel off the surface dirt, so as to achieve the effect of cleaning. Because it passes through the liquid, as long as the liquid can touch the surface, it can be cleaned in place, leaving no dead corners. It can work on every surface of multiple objects at the same time. It is very effective and fast, and can be cleaned in about 15 minutes. One of the advantages of using ultrasonic cleaning is that it can effectively restore, improve the ability of pads and components, and reduce electromagnetic interference.

SMT smart patch processing plant

Nowadays, with the prevalence of Internet of Things technology and cloud computing technology, many manufacturing companies around the world have carried out the basic construction and practical activities of smart workshops. The SMT patch processing and manufacturing industry has become the focus of smart factory practice due to its wide range of characteristics. The overall smt patch processing process will be closely integrated with the enterprise's intelligent testing, sharing the summary of the smt patch processing and manufacturing industry from the traditional factory upgrade of the smt patch processing factory.

At present, there are many in the market claiming that they can provide smart SMT factory solutions for enterprises, but in fact, after in-depth investigation, they found that basic suppliers have only made certain expansions in data statistics and display visualization. To sum up, the characteristics of these programs are still based on Kanban, statistics, and display, and they cannot be regarded as intelligent in the true sense.

So, what do we call the smart SMT patch processing plant? In fact, to put it plainly, the smart factory is only a concept. The upgrading and transformation of electronic processing enterprises should always focus on smart tools with "improving production efficiency" as the core. This smart tool. Its construction needs to be customized and matched according to the factory management concept. This intelligent tool is the direct executor of the factory concept and corresponds to it: zero defect, zero loss, and high efficiency. Therefore, the intelligent construction of SMT patch processing plants must aim at the high defect rate, large parts damage, and low efficiency of traditional factories, and eliminate waste and pursuit. Therefore, the intelligent SMT chip processing plant needs to upgrade the corresponding modules, such as: production capacity, yield, and efficiency.

Speaking of production capacity: then the main indicator of production capacity is equipment, and the realization of productivity is not empty talk. The adequacy of equipment is an important indicator to measure production capacity. For so long, we must pay attention to equipment maintenance. According to the requirements of the intelligent patch processing plant, PMC or the company's decision-making level needs to be aware of the important parameters of the equipment at all times. So how to accurately collect data, auto-diagnose, auto-confirm..., the most intelligent realization of statistics and confirmation of equipment status. This question is related to a basic point of the decision-making level's assessment of product production capacity.
