Automated Dual Piezo Jetting Valve with 10 Channel Parameters for High Precision Dispensing

Automated Jetting Dispenser Dual Piezo Valve for CCM, middle frame, MEMS device application

Dual piezoelectric jet valves are ideal for high-precision dispensing in electronics such as smartphones, pads, smartwatches, and earbuds. Their dual-actuator design delivers greater jetting force and faster response time, enabling precise control of high-viscosity fluids, including adhesives and solder pastes. These valves ensure consistent dot size, minimal satellite droplets, and excellent repeatability, even in micro-scale applications. With non-contact jetting, they support higher speed and cleaner production, making them essential in advanced micro-assembly and packaging processes.

Core Advantages

• High viscosity glue spraying: The jetting force of the valve body has increased by 20%, and can handle high viscosity glue (up to 500000mPa·s).
• Precision glue control: Dual piezoelectric drive, smaller valve opening time (0.01ms), more accurate glue spraying process parameters, and stable control of small glue volume.
  Minimum glue spraying volume 0.5nl (CPK>1.33, with water as the test medium)
• Nozzle adjustment-free: The nozzle position is fixed in the structural design. After maintenance, the nozzle position does not need ADJ calibration, and the original process operation can be quickly restored.
• Easy maintaince: The Luer connector is one-piece molded to reduce the maintenance and replacement of consumables (sealing rings, etc.)
• Strong compatibility: Standardized flow channel design, interchangeable with other valves
• Multifunctional piezoelectric controller: Can realize flow channel heating temperature control | signal trigger monitoring | valve body status monitoring | stack temperature monitoring | IO signal expansion and other functions
• Supports 10 channel parameters to switch quickly online
  Through the IO interface, parameter switching can be achieved according to process requirements
• Foolproof design to avoid misalignment of wiring harness connection, resulting in short circuit and other faults

Main appliaction

• Consumer electronics: mobile phones, tablets, smart headphones, smart watches

• Electronic packaging: chip underfill, solder paste jetting

• Biomedical: trace reagent distribution

• Optical devices: lens bonding, fluorescent glue dispensing

FAQ

Q1: Can the dual piezoelectric jet valve handle high-viscosity materials like hot melt adhesives?
A1: Yes. The dual-actuator design delivers stronger jetting force, enabling precise dispensing of high-viscosity materials.

There's flow heating channel and glue barrel heating modules avaiable.

Q2: How consistent is the dispensing performance across thousands of cycles?
A2: Dual piezo valves provide exceptional repeatability and stability. The synchronized dual-piezo structure ensures consistent dot size and volume over long production runs, critical for microelectronic components.

Q3: Is it suitable for ultra-small components and narrow spaces?
A3: Absolutely. The non-contact jetting method allows for accurate dispensing in confined areas and on delicate components, minimizing damage and ensuring high placement precision.

Q4: How does it improve cycle time in high-speed production lines?
A4: With faster response time and high-frequency operation (up to hundreds of Hz), dual piezoelectric valves significantly reduce dispensing cycle time, increasing throughput without sacrificing quality.

Q5: Can it be integrated with temperature control or heating modules?
A5: Yes. The system can be equipped with heating modules for materials that require temperature-controlled dispensing, improving flow characteristics and curing efficiency.
