Piezoelectric valve

Piezoelectric valve

Piezoelectric valve is a new high-speed injection valve independently developed by Shiqiao, with stable performance and high cost performance. It is widely used in SMT, FPC & PCB assembly industry, LED packaging industry, energy industry, electroacoustic industry, life science, optics, MEMS, RFID and other occasions requiring high precision, high consistency, high efficiency, non-contact and space constraints.

product features

  • Unique nozzle, flow channel and feeding constant temperature system ensure that the viscosity of glue is not affected by temperature and maintain ultra-high consistency
  • Piezoelectric principle, high injection frequency, up to 500 points / s, minimum 0.2mm point diameter
  • High precision nozzle and precise structure design, small stroke and strong injection force, which can effectively prevent bubbles and scattered points
  • Online disassembly, fast maintenance and cleaning, reducing downtime
  • Non contact, eliminate z-axis movement, and realize high-speed dispensing operation for smooth or uneven surface
  • It is applicable to a wide range of fluid viscosity, and its flexibility can meet the changing dispensing needs

focus on app

  • Underfill (undefil)
  • Frame bonding and sealing (hot melt)
  • Precision coating
  • Dam and FLL
  • Pin encapsulation
  • Cover bonding / edge bonding
