Easy maintenance Piezo Jet valve​ in FATP / Final Assembly, Test and Pack


Piezo jet valves play a crucial role in modern smartphone and PCB assembly, especially during the FATP (Final Assembly, Test and Pack) stage. Their non-contact, high-speed, and ultra-precise dispensing capabilities make them ideal for bonding and sealing delicate components such as camera modules, fingerprint sensors, flexible PCBs, and EMI shields. They are also widely used in applying underfill, thermal interface materials, UV adhesives, and conformal coatings on densely populated mainboards.

These valves excel in dispensing micro-dots of high-viscosity fluids (up to tens of thousands of mPa·s), supporting fast cycle times with jetting frequencies over 300Hz. Their contactless operation avoids damage to sensitive components, and their ability to maintain consistent dot size improves product quality and reduces rework.
With rising demand for miniaturization, automation, and production consistency, piezo jet valves are becoming essential in next-generation electronics manufacturing lines.

FAQ

Q1. What factors should I consider when selecting a piezo jet valve for my application?
A1: Key factors include the viscosity of your adhesive, required dispensing volume, dot size tolerance, jetting speed, compatibility with your automation system, and maintenance requirements.

Q2. Can the piezo jet valve handle high-viscosity materials like thermal paste or epoxy?
A2: Yes. Piezo jet valves are designed to handle a wide range of viscosities, including high-viscosity materials such as thermal interface compounds, UV adhesives, and epoxies, while maintaining consistent dispensing performance.

Q3. What maintenance is required for long-term valve performance?
A3: Routine cleaning of the nozzle, proper adhesive filtration, and regular system calibration are essential. Some models offer self-cleaning features or clog detection to reduce downtime.
