For SMT manufacturers relying on JUKI pick-and-place machines, high-quality filter cotton is a core component to maintain equipment precision, extend service life and ensure stable production. Dirty or mismatched filters can cause vacuum failure, nozzle clogging and even PCB assembly defects, directly affecting production efficiency and product yield. This guide systematically sorts out the matching filter cotton models for mainstream JUKI pick-and-place machine series, and shares professional selection and maintenance suggestions, helping you optimize SMT production line management.
Core Functions of JUKI Pick-and-Place Machine Filter Cotton
JUKI pick-and-place machine filter cotton mainly undertakes three key roles in SMT production. First, it filters dust, solder paste residues and tiny particle impurities in the air path, preventing them from entering the vacuum system and nozzle to avoid suction failure. Second, it isolates oil and water vapor in the compressed air, protecting the internal precision components of the machine from corrosion. Third, it maintains stable air pressure in the equipment, ensuring the nozzle can accurately pick and place components.
There are two main types of filter cotton for JUKI machines: standard dust filter cotton for basic impurity filtration and HEPA filter cotton for high-precision production scenarios. HEPA filters can remove 99.97% of particles with a size of 0.3 microns, which is suitable for fine component assembly such as 01005 chips and BGA components. Choosing the right filter cotton model according to the machine type is the premise of ensuring filtration efficiency.

Key Tips for Filter Cotton Selection & Replacement (Improve Equipment Efficiency)
- Selection Principles (Avoid Mismatch Risks)
- Prioritize original or original-standard filter cotton: Non-standard filter cotton has poor sealing and low filtration efficiency, which may cause vacuum system damage in 3-6 months.
- Match according to production scenario: Choose HEPA filter cotton for fine component assembly (01005, BGA), and standard dust filter cotton for ordinary component production to save costs.
- Unify spare parts models: For enterprises with multiple JUKI models, prioritize models with universal filter cotton (such as E3052729000) to reduce inventory pressure.
- Scientific Replacement Cycle (Extend Equipment Life)
- Standard working environment (low dust, stable temperature and humidity): Replace core filter cotton every 800-1000 working hours, and auxiliary filter every 1500-2000 working hours.
- Harsh environment (high dust, high humidity): Shorten the replacement cycle by 30%, and clean the filter cotton surface with dry air every 200 working hours to extend temporary service life.
- Mandatory replacement after failure: If the machine appears nozzle suction weakness, component missing placement or vacuum alarm, replace the filter cotton first, which can solve 80% of similar faults.
- Replacement Operation Points (Ensure Filtration Effect)
- Cut off the power supply and air source before replacement to avoid safety accidents.
- Check the filter seat for dust and oil accumulation, and clean it with alcohol cotton to ensure tight fit between the new filter and the seat.
- After replacement, test the vacuum pressure of the machine. The standard vacuum value of JUKI machines should be above -90KPa, otherwise it is necessary to check whether the filter is installed in place.
