High frequency Piezo Jet Valve Solutions for IC and Sensor Packaging Applications

Piezo jet valves enable ultra-precise, non-contact adhesive dispensing for semiconductor IC and sensor packaging. Ideal for underfill, die attach, and MEMS sealing, they handle low-to-high viscosity materials with nanoliter precision. With high-speed jetting, excellent repeatability, and easy integration, piezo valves improve yield and efficiency in advanced packaging lines.
The piezoelectric jetting valve is an ideal solution for semiconductor and high-precision dispensing applications requiring high-speed piezo jetting performance.

FAQ

Q1: What materials can a piezo jet valve dispense in IC or sensor packaging?
A1: Piezo jet valves can handle a wide range of materials, including underfill epoxy, die attach adhesive, silicone sealants, and UV-curable resins. They support viscosities from 1 to 50,000 mPa·s with excellent repeatability.

Q2: How does non-contact dispensing benefit semiconductor and MEMS assembly?
A2: Non-contact dispensing prevents mechanical damage to delicate structures like bare dies or MEMS sensors. It also allows precise adhesive placement in narrow gaps and complex geometries.

Q3: Can piezo valves be used in high-throughput packaging lines?
A3: Yes. With jetting speeds exceeding 1000Hz, piezo jet valves are ideal for high-volume production. They maintain consistent dot size, reduce cycle time, and integrate easily with automation and vision systems.

Q4: How do piezo valves ensure cleanliness and reliability in cleanroom environments?
A4: Piezo valves are designed with minimal dead volume, easy-to-clean nozzles, and sealed structures to prevent contamination.
