In electronics packaging, semiconductor manufacturing, and optoelectronics, dispensing processes face increasingly stringent demands: micron-level line width precision, consistent shot-to-shot volume under high-speed operation, and compatibility with fluids of varying viscosities and properties. Traditional contact type dispensing valves, limited by needle wear, frequent alignment needs, and slow speeds, struggle to meet the requirements of modern production lines. The Piezoelectric Jetting Valve, driven by piezoelectric ceramic technology and non-contact jetting principles, delivers four core advantages—high efficiency, high precision, broad compatibility, and easy maintenance—making it the ideal choice in precision fluid control.
Core Drive: Audiwell Piezoelectric Ceramic for Stability and Long Life
The heart of the piezoelectric jetting valve is its drive unit, featuring high quality piezoelectric ceramics from Audiwell. This material offers excellent electrostrictive performance and fatigue life, ensuring outstanding stability and lot to lot consistency even during long term high frequency operation. Whether running for millions of cycles or coping with varying ambient temperatures, the piezoelectric ceramic delivers a stable, repeatable impact force, ensuring high uniformity in dot size, position, and shape. The ultra long service life dramatically reduces spare part replacement frequency, saving significant maintenance and operating costs.
Minimal Maintenance: Quick-Release Fluid Body + Fast Stroke Adjustment
Conventional jetting valves often require tedious disassembly and recalibration when cleaning or changing fluids, resulting in long production stoppages. This product features a quick release fluid body that allows tool less removal of the fluid path, making cleaning and fluid change over simple and fast. Additionally, the fast stroke adjustment mechanism enables operators to precisely set the plunger stroke with a simple rotation, eliminating complex calibration. Together, these two design innovations drastically reduce routine maintenance time and significantly improve overall equipment effectiveness (OEE).
High Efficiency: Up to 1500 Hz Jetting Frequency
In high volume production such as solder paste jetting for smartphones, chip underfill, or LED phosphor dispensing, cycle time directly determines throughput. The Piezoelectric Jetting Valve achieves a maximum operating frequency of 1500 Hz—meaning 1500 non contact jetting events per second. Droplets are ejected at high speed from the nozzle and land precisely on target. Compared to pneumatic or solenoid driven valves, the piezoelectric jetting valve responds faster and operates at a higher frequency, easily keeping pace with high speed motion platforms and vision systems, enabling customers to achieve substantial productivity gains.
Broad Compatibility: Works with Any Dispensing Platform
Dispensing systems from different manufacturers often use differing control signals and mechanical interfaces. This piezoelectric jetting valve features standardized electrical and mounting interfaces, allowing seamless integration with any dispensing platform on the market—whether a 3 axis desktop robot, a gantry system, or a six axis arm. This plug and play compatibility means that equipment upgrades or line retrofits do not require replacing existing platforms, maximizing protection of the customer’s current investment.
High Precision: Minimum 1 nL Shot Size, 0.15 mm Line Width
In precision dispensing, excessive fluid volume can cause short circuits, sagging, or interference, while insufficient volume leads to adhesion failure. This product achieves a minimum shot size of 1 nanoliter (nL) , enabling 0.15 mm ultra fine line width with a dispensing accuracy of 99% . Whether printing fine line conductive silver paste or performing precise underfill penetration into tiny gaps, the piezoelectric jetting valve delivers consistent droplet size with no stringing or satellite drops. Combined with high precision vision alignment and closed loop feedback, it easily handles chip scale packages with pitches as fine as 0.2 mm.
