High precision Piezo Jet Valve​ for CCM/Camera Compact Module Application

Piezo jetting valves offer high-speed, non-contact dispensing for CCM (Compact Camera Module) assembly. Ideal for lens bonding, IR filter sealing, and VCM fixing, they deliver ultra-precise micro-droplets of UV or epoxy adhesives. With fast response, high repeatability, and compatibility with automated lines, piezo valves enhance yield and accuracy in miniaturized optical module production.

Core Advantages

• Precise control: high dispensing position accuracy, precise glue control, no bubbles, no drawing, no overflow
• High consistency glue volume: ensure packaging consistency
• Non-contact injection: compact product structure, non-contact dispensing to avoid contamination or damage to optical components
• Compatible with different types of glue, such as UV glue, black glue, epoxy glue, etc.

Main appliaction

• Lens module fixing, lens bonding, IR filter encapsulation: UV glue (ultraviolet light curing glue)
• Lens shading, light-proof sealing, CCD shading and light leakage prevention: black glue (light-shielding glue)
• Lens and bracket structure bonding, VCM module dispensing: epoxy glue (Epoxy)

FAQ

Q1: Why is a piezo jetting valve preferred for adhesive dispensing in CCM assembly?
A1: Piezo jetting valves provide high-speed, non-contact dispensing with extremely small and precise droplet volumes , making them ideal for CCM processes like lens bonding, IR filter sealing, and VCM fixation, where accuracy and cleanliness are critical.

Q2: What types of adhesives are commonly used with piezo valves in CCM production?
A2: Typical adhesives include UV-curable adhesives (for lens bonding and filter sealing), black epoxy (for light-blocking), and structural epoxy (for motor module fixing). These adhesives usually have viscosities between 30–1000 cP and require precise volume control.

Q3: Can piezo valves handle high-speed production lines in smartphone camera module assembly?
A3: Yes. Piezo jetting valves are designed for high-frequency operation, enabling high-throughput dispensing while maintaining consistent droplet size and placement, even on fast-moving assembly lines.

Q4: How does non-contact dispensing benefit CCM manufacturing?
A4: Non-contact dispensing prevents damage or contamination to sensitive optical components like lenses and filters. It also allows for greater flexibility in dispensing on uneven or hard-to-reach surfaces.

Q5: What factors influence the performance of a piezo jetting valve in CCM applications?
A5: Key factors include fluid viscosity, nozzle size, drive waveform settings, temperature control, and droplet volume calibration. Proper setup ensures repeatability, avoids clogging, and maintains long-term reliability.
