Absorbent sponge rollers are mainly used for cleaning, water absorption, static protection, and wet processing in PCB manufacturing. 

Their features, such as high absorbency, softness, and durability, make them crucial in the process. 

When selecting absorbent sponges, factors like material, absorbency, size, and durability should be considered to ensure efficiency and reliability in use.

Characteristics:

1.High Absorbency: Can quickly absorb a large amount of water.

2.Soft and Durable: Not easily damaged, suitable for long-term use.

3.Chemical Resistance: Stable when used with chemical solutions.

4.Dense Structure: Effectively cleans surfaces without damaging the PCB.

5.Good Recovery: Quickly returns to its original shape after compression.

Applications:

1.PCB Cleaning: Removes solder residues and other contaminants from the circuit board.

2.Wet Processing: Absorbs excess solutions to prevent contamination.

3.Static Discharge Protection: Protects PCBs from electrostatic damage.

4.Precision Cleaning: Cleans hard-to-reach small areas.

5.Printing Equipment Cleaning: Used to clean printing equipment during the PCB manufacturing process.
