High Speed Jetting Valve​ PCB FPC Dispensing Electronics Pulse Jet Valve

High-speed Jetting Valves Applicable for PCB/FPC Dispensing in Electronics

Piezo jet valves are advanced adhesive dispensing valves widely used in PCB and FPC manufacturing processes, offering fast, precise, and non-contact micro-dispensing capabilities. These jetting valves use piezoelectric actuation to deliver high-frequency adhesive droplets without touching the substrate, making them ideal for sensitive electronics and fine-pitch circuit assembly.

These valves are compatible with a wide range of adhesives including epoxy, UV-curable adhesives, and can operate at viscosities ranging from 1 to 500,000 cps. Their high-speed jetting capability (up to 1200Hz) ensures fast cycle times, while non-contact dispensing reduces the risk of component damage and contamination.

Globally, piezo jetting valves are adopted by leading manufacturers in China, South Korea, Vietnam, and Europe, supporting mass production in consumer electronics, automotive modules, and industrial control systems. OEMs and EMS providers value their reliable performance, compact design, and easy integration into automated production lines.

Core Advantages

• Non-contact jetting technology, suitable for small spaces and fine structures
• High controllability of dispensing, suitable for high-precision/high-consistency processes
• Supports a variety of glues, adapting to various application requirements
• Easy to automate and integrate, suitable for mass production line deployment

Main appliaction

• Packaging and bonding in the field of precision electronics manufacturing. Glue dispensing is mainly used for component fixing, waterproofing and dustproofing, stress buffering, etc.
• PCB/FPC assembly
• Consumer electronics (such as mobile phones, wearable devices)
• Automotive electronics

FAQ

Q1: Why are piezo jet valves ideal for adhesive dispensing in PCB/FPC applications?
A1: Piezo jet valves provide non-contact, high-precision dispensing, which is critical for delicate and densely populated PCB/FPC assemblies. They offer consistent micro-droplet control, reducing the risk of damage, overflow, or contamination.

Q2: What types of adhesives are compatible with piezo jet valves for PCB/FPC processing?

A2: Common adhesives include UV-curable adhesives, epoxy, silicone, and conductive pastes. These valves can handle a wide viscosity range and offer reliable performance across various materials used in FPC stiffening, underfill, and localized sealing.

Q3: What are the typical applications of piezo jet valves in the PCB/FPC industry?
A3: Key applications include FPC stiffener bonding, underfill for chip packaging, dot/line dispensing of conductive or insulating adhesives, and local silicone sealing for moisture protection. All require micro-precision, which piezo valves excel at.

Q4: How does piezo jetting improve production efficiency in PCB/FPC lines?
A: With jetting frequencies up to hundreds of Hz and non-contact operation, piezo valves support high-speed, automated dispensing with minimal downtime. This leads to faster cycle times, higher yields, and lower maintenance compared to traditional contact systems.
