Why is it necessary to use a high power industrial cleaning machine for circuit board cleaning?

1. Prevent structural damage.

When using an easy-to-use industrial cleaning machine to clean the circuit board, the circuit board can be placed in the inner slot, and the reason why it is necessary to use high-power cleaning equipment instead of conventional cleaning is to avoid the circuit board being damaged. Because the structure of the circuit board is extremely fragile, and the industrial cleaning machine has strong protection for the circuit board, the ultrasonic control of the panel can be adjusted, which can effectively prevent structural damage.

Second, the cleaning ability is strong to ensure the cleaning effect.

The fragile structure of the circuit board also requires a super cleaning effect, so only the high-power industrial cleaning machine can achieve the difference before and after cleaning, and it can be clearly seen that the surface of the circuit board after using the industrial cleaning machine is clean and beautiful, so the cleaning effect is ensured.

3. No need to maintain equipment.

Usually the ordinary equipment has a long maintenance time after cleaning the circuit board, and the maintenance cost is relatively high, but the high-power industrial cleaning machine is not, it is made of high-quality stainless steel, which has strong anti-corrosion, and has a filter drainage hole, and the filter screen is added in the drainage hole to facilitate the user's cleaning, and the cleaning efficiency of the circuit board is improved.

This is because only a high-power washer has the ability to thoroughly remove the corrosive residue that adheres to the copper foil gap of the line, ensuring the quality of the PCB delivery.

Circuit boards are an important part of electronic equipment, and their proper operation requires ensuring the cleanliness and quality of circuit boards. During the use of the circuit board, the conductive surface on the circuit board will be affected due to the accumulation of dust, oil stains, dirt and other substances and the splashing of corrosive liquids, thereby affecting the performance of the circuit board. Therefore, it is particularly important to carry out circuit board cleaning.

In general, the following cleaning methods are used for circuit board cleaning:

1.Chemical Cleaning Method: This method usually uses a chemical cleaning agent to remove dirt from the surface of the circuit board through a chemical reaction.

This method has a simple principle and obvious cleaning effect, which is suitable for deep cleaning of circuit boards. However, it should be noted that chemical cleaning agents have a certain toxicity to the human body and need professional protection.

2.Mechanical cleaning method: This method usually uses a mechanical cleaning machine to clean the surface of the circuit board by brushing the surface of the circuit board with a high-speed rotating brush and a high-pressure water flow. This method has a fast cleaning speed and good effect, and is suitable for simple cleaning of circuit boards.

3.Aerosol cleaning method: This method usually uses an aerosol cleaning machine to clean the dirt on the surface of the circuit board through high-pressure aerosol dry cherry blossoms. This method has a fast cleaning speed and is suitable for cleaning some parts that are difficult to clean mechanically.

It should be noted that different cleaning methods are suitable for different cleaning occasions, and they need to be selected according to the actual situation of the circuit board. At the same time, when cleaning the circuit wide board, it is necessary to take protective measures to avoid damage and injury to the human body caused by chemical cleaning agents and mechanical cleaning machines. When using cleaning agents, follow the instructions for use and use them in moderation to avoid excessive use and residual cleaning agents.

In short, circuit board cleaning is an important part of ensuring the normal operation of electronic equipment, and the appropriate cleaning method should be selected for cleaning.

Circuit board cleaning generally uses Liangsun's special cleaning agents, such as deionized water, alcohol, acetone, chlorinated solution, etc. The specific choice of cleaning agent should be based on the material of the circuit board, the type and degree of spike key of the contaminant, the type of cleaning equipment and other factors. At the same time, during the cleaning process, it is necessary to pay attention to protect the electronic components on the circuit board to avoid damage.

The cleaning advantages of the electronic circuit board ultrasonic cleaning machine are all obtained through professional identification, and you can use it with confidence!

High precisionBecause the energy of ultrasonic waves can penetrate fine gaps and small holes, it can be applied to the cleaning of electronic circuit boards of any shape and complexity. If the electronic circuit board to be cleaned is more complex, there are some gaps and openings that are difficult to clean by ordinary methods. Ultrasonic cleaning is often the only cleaning method that can meet their special technical requirements.

Fast and efficient. Ultrasonic cleaning is much faster than conventional cleaning methods in terms of dust removal and descaling of electronic circuit boards. The labor-saving benefits of ultrasonic cleaning often make it the most economical way to clean.

Good consistency. Regardless of whether the electronic circuit board to be cleaned is large or small, simple or complex, single piece or batch or on an automatic assembly line, the use of ultrasonic cleaning can obtain an incomparable and uniform cleanliness of manual cleaning.

The importance of frequency.

Noise is generated when the operating frequency is very low (within the range of human hearing). When the frequency is lower, the operating noise not only becomes loud, but may exceed the safety noise limits set by the Occupational Safety and Health Act or other regulations. In applications that require high power to remove dirt without concern about damage to the surface of the workpiece, a lower cleaning frequency is usually chosen.

The cleaning frequencies in this frequency range are often used to clean large, heavy parts or workpieces with high-density materials. High frequencies are often used to clean smaller, more delicate parts, or to remove tiny particles. High frequencies are also used in applications where the surface of the workpiece is not allowed to be damaged.

The use of high frequencies can improve cleaning performance in several ways. As the frequency increases, the number of cavitation bubbles increases lilinally, resulting in more and denser shock waves that allow them to enter smaller gaps. If the power remains the same, the cavitation bubble becomes smaller and the energy released is reduced accordingly, which effectively reduces the damage to the surface of the workpiece.

Another advantage of high frequencies is the reduction of the viscous boundary layer (the Bonuri effect), which allows ultrasound to detect very fine particles. This situation is similar to the pebbles at the bottom of a creek when the water level drops.

Because there are various components and even more delicate devices on the electronic circuit board, and the surface of the electronic circuit board is uneven and there are many small slits, the cleaning of the circuit board must of course use a higher frequency. The frequency of foreign data is recommended in. However, in reality, some people think that the higher the frequency, the easier it is to cause damage to the electronic circuit board, and the low frequency is often safe, which is completely wrong.

The selection of chemical solvents takes into account the influence of the physical properties of the cleaning solution on ultrasonic cleaning, among which vapor pressure, surface tension, viscosity and density should be the most significant influencing factors. Temperature can affect these factors, so it also affects the efficiency of cavitation.

The effective way to clean the silicone oil of the FPC circuit board is to use Jiongsheng silicone oil cleaning agent to clean, which is neutral, environmentally friendly and non-corrosive, and has passed the RoHS test.

Instructions for use: Silicone oil cleaner is diluted 1:10-20 times with water. Severe contamination requires an increase in the concentration of the solution.

Heating the solution (60 to 80 degrees Celsius) or using an ultrasonic cleaning bath can significantly reduce the cleaning time. Rinse thoroughly immediately after removal of the wash from the solution. Rinse with water three times to ensure complete removal of contaminants and residual traces of the cleaning solution.

Dry carefully after washing, using a lint-free cloth or hot air jet. The washing time is 15-30 minutes; More than 50 can be sprayed.

Circuit board cleaners use water-based solvents as cleaning agents. The circuit board cleaning machine is suitable for pre-plating treatment and post-plating cleaning of electroplating parts, clock and watch parts, hardware and machinery parts, bead jewelry, lenses, glasses frames and glassware.
