Long-term stability Dispense Valve Jetting type for Car light
control motherboard
Piezo jet valves enable precise, non-contact adhesive dispensing on automotive
headlamp control PCBs. Ideal for underfill, thermal paste, and
conformal coating applications, they support high-viscosity
materials and fine dot control. With high-speed jetting and
excellent repeatability, piezo valves improve production efficiency
and reliability in LED and ADB headlight module assembly.
Core Advantages
- High dispensing accuracy and consistency: glue spraying scattering rate <0.5%
- High spraying speed/frequency: match SMT beats and improve beat efficiency
- Strong valve body compatibility: can be adapted to existing automation platform integration
Main appliaction
Most of the car lighting control motherboards are complex PCB
structures, including multi-channel LED drivers, power management,
CAN communication, inductor and capacitor devices, etc.
Piezoelectric injection valves are mainly used for the following
precision dispensing processes:
Chip/component reinforcement (Underfill or Corner Bond) to prevent
thermal expansion or vibration from causing solder joint cracking;
Thermal conductive glue dispensing to improve heat dissipation
efficiency and ensure long-term stable operation of the entire lamp
module.
Tri-contamination coating (local precision spraying) to accurately
control the coating thickness and range to prevent short circuits
or corrosion.
Structural parts bonding/sealing dispensing to meet structural
fixation and waterproofing requirements.

FAQ
Q1: What are the key benefits of using a piezo jet valve in
automotive headlamp control PCB assembly?
A1: Piezo jet valves provide precise, non-contact dispensing for
high-viscosity adhesives like thermal paste and epoxy. They ensure
accurate dot placement on densely packed PCBs, improve production
yield, and meet automotive reliability standards.
Q2: Can piezo valves handle high-viscosity materials used in
thermal management and sealing?
A2: Yes. Piezo valves are designed to dispense materials with
viscosities ranging from low to over 50,000 mPa·s, including
thermal interface compounds, underfill epoxies, and conformal
coatings used in LED driver circuits.
Q3: How does a piezo jet valve help meet automotive-grade quality
requirements?
A3: By delivering consistent dot volume, minimizing air entrapment,
and enabling precise control in confined areas, piezo valves help
manufacturers meet stringent automotive standards like IP67
sealing, anti-vibration stability, and long-term thermal
reliability.
Q4: What maintenance or cleaning is required for long-term stable
operation?
A4: Routine cleaning of the nozzle and valve chamber, proper
adhesive filtering, and scheduled calibration help maintain
performance. Some systems include self-diagnostics and clog
detection for predictive maintenance.
Q5: Is integration with existing automotive production lines
possible?
A5: Yes. Most piezo jet valves support integration with vision
systems, motion platforms (XYZ tables or robots), and MES systems.
Their compact design makes them ideal for inline dispensing in
high-throughput automotive PCB assembly lines.
