As modern manufacturing continues to trend toward miniaturization and higher precision, microfluidic dispensing has become a core process in the semiconductor, 3C electronics, optoelectronics, medical device, and new energy industries. Traditional pneumatic valves and contact-type dispensing valves, due to their low precision, slow response, and tendency to produce dispensing defects, can no longer meet production demands. The SZLKTE piezoelectric precision microdispensing valve is a specialized non-contact jetting dispensing solution developed specifically to address the pain points of microdispensing in these industries, helping manufacturers achieve high-precision, high-speed, and highly stable microdispensing production.
Traditional dispensing equipment faces multiple bottlenecks in micro-volume, high-precision production:
• Poor dispensing consistency: Affected by air pressure fluctuations, needle wear, and changes in fluid viscosity, traditional valves exhibit large deviations in dispensed volume, failing to meet the tolerance requirements of miniature components.
• Stringing and trailing defects: Due to slow mechanical response, stringing and trailing often occur during dispensing, leading to product contamination and reduced yield.
• Substrate damage and contamination: Contact-type dispensing can scratch fragile substrates such as FPCs and wafers, while residual adhesive on the needle may cause cross-contamination of products.
• Low production efficiency: Pneumatic valves have slow response times and low dispensing frequencies, limiting the throughput of automated production lines.
• Frequent maintenance and high costs: With short mechanical lifespans, frequent replacements and downtime for maintenance drive overall production costs sky-high.
By adopting advanced piezoelectric drive technology, our microdispensing valve converts electrical pulse signals into precise micro-vibrations, enabling non-contact, high-speed jetting dispensing and perfectly resolving the aforementioned industry pain points:
• Ultra-high precision and consistency: Minimum dot diameter can reach 0.18 mm, with volumetric accuracy controlled within ±1%, ensuring stable and uniform micro-dot formation.
• Zero-defect dispensing: Non-contact jetting effectively eliminates stringing, trailing, and overflow issues, significantly improving product yield.
• Microsecond-level high-speed response: Response speed far exceeds that of traditional pneumatic valves, with operating frequencies up to 1000 Hz, making it ideal for high-speed mass production.
• Wide fluid compatibility: Capable of stably dispensing various fluids with viscosities ranging from 1 to 1,000,000 mPa·s, including UV adhesives, epoxy resins, solder pastes, thermally conductive greases, and biochemical reagents.
• Extremely long lifespan and stable operation: Featuring a low-wear structural design, it boasts a service life of up to 1.5 billion cycles, reducing maintenance frequency and lowering production costs.
• Intelligent adjustable control: Supports programmable pulse and waveform parameter adjustments, flexibly adapting to different product and process requirements.
Addresses the challenges of microdispensing underfill adhesives, encapsulation adhesives, and solder pastes in flip-chip and wafer-level packaging. Non-contact dispensing protects delicate chips and wafers, ensures uniform filling without voids, and meets stringent packaging precision requirements.
Suitable for precision dispensing and sealing of camera modules, FPC flexible boards, PCB components, and miniature connectors. High-speed dispensing greatly boosts production efficiency while preventing component scratches and overflow defects.
An ideal choice for die bonding, lens fixation, and phosphor coating of Micro/Mini LED chips. Ultra-fine dispensing ensures uniform glue dots and consistent light output, supporting large-scale, high-precision production of optoelectronic devices.
Non-contact dispensing avoids cross-contamination and is applicable to biochip spotting, diagnostic reagent dispensing, and medical device bonding. It can stably dispense trace amounts of biochemical fluids, meeting medical-grade cleanliness standards.
Suitable for dispensing high-viscosity thermally conductive greases, sealants, and potting compounds used in lithium battery and photovoltaic module assembly. Maintains stable dispensing precision even during prolonged continuous operation, ensuring the safety and stability of new energy products.
