In modern electronics manufacturing, PCB and FPC assemblies demand high-speed, highly accurate adhesive dispensing. From coating fine traces to protecting delicate components, stability in dispensing is critical for product reliability. Traditional needle dispensing methods often face challenges such as inconsistent flow, stringing, or material waste, particularly when dealing with ultra-high viscosity adhesives or micro-scale applications.

This is where next-generation piezoelectric jet valves—such as the KPS2000 and KPS4000—come into play. Designed for non-contact, high-frequency dispensing, these jetting solutions bring precision and repeatability to processes that were once prone to error.

Why Jet Valves Make a Difference

• Non-Contact High-Speed Dispensing
  Piezo jet valves enable micro-liter shots at high frequency, reducing cycle times without sacrificing accuracy.
• Wide Material Compatibility
  From UV adhesives to PUR and corrosive chemistries, advanced valves can handle a variety of viscosities, making them suitable for both rigid PCBs and flexible substrates.
• Real-Time Process Control
  Features like glue pulse monitoring, closed-loop fault detection, and on-the-fly parameter switching ensure consistency across high-volume runs.
• Reduced Maintenance and Cost
  With modular designs and improved nozzle calibration, KPS series valves minimize downtime and extend service life.
   

Applications in PCB and FPC Assembly

As electronics become thinner and more compact, PCB and FPC manufacturers face increasing demands for precision in dispensing. Jet valves address these needs in several ways:

• Solder Mask and Conformal Coating: Achieving thin, uniform layers without overflow.
• Micro-Component Bonding: Reliable dot placement for compact modules such as camera sensors and MEMS.
• Encapsulation and Underfill: Stable flow paths for protection against moisture, heat, and vibration.
   

Why It Matters for Taiwan’s PCB/FPC Industry

Taiwan is home to some of the world’s leading PCB and FPC manufacturers, supplying to industries ranging from smartphones to automotive electronics. As production scales, even minor inconsistencies in adhesive dispensing can lead to increased defect rates and costly rework.

By adopting advanced jet valves like the KPS2000 and KPS4000, factories in Taiwan can improve process stability, reduce material waste, and maintain higher throughput. More importantly, integrating these valves into smart manufacturing lines ensures that PCB/FPC producers stay competitive in the global supply chain.

 
Conclusion

For PCB and FPC manufacturers, dispensing stability is no longer optional—it’s essential for maintaining quality, reliability, and efficiency. Next-generation jet valves deliver the precision, repeatability, and process control required to meet the demands of modern electronics. As advanced packaging and miniaturization continue to shape the industry, solutions like the KPS2000 and KPS4000 provide the foundation for consistent, scalable production.
