FAQ

Q1: What types of fluids can a piezo jet valve dispense in precision electronics applications?
A1: Piezo valves are compatible with a wide range of fluids, including UV adhesives, epoxy, thermosetting adhesive, silicone, flux, red glue and conductive silver paste. They are especially suitable for low-to-medium viscosity fluids used in micro-assembly.

Q2: How accurate is the dispensing volume with a piezoelectric valve?
A2: Piezo jet valves offer ultra-precise volume control, with repeatability as high as ±1%. This ensures consistent dot size and placement, which is critical in precision electronics like CCM, MEMS, and micro speakers.

Q3: Is the piezo valve suitable for high-speed production lines?
A3: Yes. With a dispensing frequency up to 1000Hz or more, piezoelectric valves support high-throughput production while maintaining precision, making them ideal for automated SMT, PCB, and optical module assembly lines.

Q4: Does the valve support non-contact dispensing?
A4: Absolutely. Piezo jet valves use non-contact jetting, which avoids component damage and enables dispensing into hard-to-reach or narrow spaces, such as in microelectronic or 3D-structured parts.

Q5: How does the piezo valve maintain long-term stability?
A5: Thanks to its closed-loop piezo control and durable design, the valve delivers stable performance over millions of cycles, reducing maintenance downtime and ensuring reliable operation in mass production.
