Applicable processes

How to use

• Cleaning is typically performed using ultrasonic or spray methods, with a small portion requiring manual brushing.
• The entire automated inline cleaning process takes 5 to 30 minutes, with specific durations adjustable based on product requirements.
• The optimal temperature for cleaning and rinsing solutions is maintained between 50–60°C. Hot air and baking temperatures range from 80–110°C, with specific settings adjusted according to product requirements. Ensure all residual moisture on PCBA is completely evaporated.
• After a period of operation, residue accumulation in the cleaning solution reduces cleaning efficacy and compromises PCBA cleanliness. Regular replenishment or replacement of the cleaning solution is required based on actual usage. For automatic inline cleaning, this is recommended every 3–7 working days; for offline ultrasonic cleaning, every 2–4 hours (depending on the quantity of PCBA being cleaned).
• After a period of rinsing, cleaning agent concentration in the rinse solution increases, diminishing PCBA cleanliness. Rinse solutions should be replaced regularly based on actual usage. At minimum, ensure rinse solutions are replaced after 2–4 hours of rinsing across 3 rinse tanks. (Depending on the quantity of PCBA being cleaned).

Precautions

After opening this product and removing the portion for use, the lid must be tightly secured to prevent the cleaning agent from evaporating.

Used cleaning agent must not be stored in the same container as unused cleaning agent. Once opened, if any cleaning agent remains in the container, it must not be left exposed to air; the lid should be tightly screwed on promptly.

Keep containers holding cleaning agent clean to prevent contamination from dirt or other substances, which may compromise the cleaning agent's quality.

Before cleaning PCBA boards, test the cleaning agent's solubility on PCB and component silkscreen printing and solder mask.

After rinsing, ensure no cleaning agent residue remains on the PCBA board surface or components.

After baking, ensure no cleaning agent or deionized water residue remains on the PCBA surface or components.

After continuous cleaning for an extended period, it is recommended to add an appropriate amount of compatible defoamer for enhanced foam suppression.

Transportation and storage

Transport as non-hazardous, non-corrosive chemicals.

Store away from light and heat in sealed containers.

Shelf life is 12 months when sealed.

Individual packages may be stacked no higher than two layers. The bottom layer must be secured with non-slip pallets to prevent crushing, deformation, or tipping.
