Overview
With the continuous miniaturization and high-precision upgrading of modern manufacturing, micro fluid dispensing has become a core process for semiconductors, 3C electronics, optoelectronics, medical devices and new energy industries. Traditional pneumatic and contact dispensing valves can no longer meet production requirements due to low accuracy, slow response and easy generation of dispensing defects. The SZLKTE Piezoelectric Precision Micro Dispensing Valve is a professional non-contact jet dispensing solution developed to solve industry micro-dispensing pain points, helping manufacturers achieve high-precision, high-speed and high-stability micro-dot dispensing.
Core Pain Points of Traditional Micro-Dispensing Technology
Traditional dispensing equipment faces multiple bottlenecks in micro-volume and high-precision production:
- Poor dispensing consistency: Affected by air pressure fluctuation, needle wear and fluid viscosity change, traditional valves have large dot volume deviation, which cannot meet the tolerance requirements of micro-components.
- Stringing and tailing defects: Slow mechanical response easily causes adhesive wire drawing and tailing during dispensing, resulting in product contamination and low yield rate.
- Substrate damage & contamination: Contact dispensing scratches fragile substrates such as FPC and wafers, and residual glue on the needle causes cross-contamination of products.
- Low production efficiency: Pneumatic valve has slow response speed and low dispensing frequency, which restricts the capacity of high-volume automated production lines.
- Frequent maintenance & high cost: Short service life of mechanical structures leads to frequent replacement and shutdown maintenance, increasing overall production costs.
SZLKTE Piezoelectric Valve Core Advantages
Adopting advanced piezoelectric driving technology, our micro dispensing valve converts electric pulse signals into precise micro-vibration, realizing non-contact high-speed jet dispensing, and perfectly solving the above industry pain points:
- Ultra-high precision & consistency: Minimum dispensing dot size up to 0.18mm, volume accuracy within ±1%, stable and uniform micro-dot molding.
- Zero defect dispensing: Non-contact jetting effectively eliminates stringing, tailing and overflow problems, improving product yield significantly.
- Microsecond-level high speed: Far faster response than traditional pneumatic valves, with working frequency up to 1000Hz, adapting to high-speed mass production.
- Wide fluid compatibility: Steadily dispenses various fluids with viscosity from 1 to 1,000,000 mPa·s, including UV glue, epoxy resin, solder paste, thermal grease and biochemical reagents.
- Long service life & stable operation: Low wear structural design, with service life up to 1.5 billion cycles, reducing maintenance frequency and production cost.
- Intelligent adjustable control: Support programmable pulse and waveform parameter adjustment, flexible adaptation to different products and process requirements.
