Features of Zirconia Ceramic Piezoelectric Injector Pin
- The injector pin achieves a flexural strength of >1,200 MPa, enabling reliable operation under continuous high-frequency impact. This strength ensures long-term stability in production lines.
- With a fracture toughness of ~10 MPa·m¹ᐟ², zirconia resists sudden breakage under vibration or thermal shifts. This property reduces downtime caused by part failure.
- Independent testing shows hardness above HV 1,200, which protects the pin from abrasion when dispensing filled adhesives and conductive pastes.
- Zirconia Ceramic Piezoelectric Injector Pin withstands over 10 million dispensing cycles before significant wear occurs. This extended lifecycle reduces replacement frequency and cost.
- The ceramic is chemically stable in pH 2–12 environments, allowing safe use with acids, bases, and aggressive solvents. This compatibility expands its application range.
- Field reports confirm that zirconia pins maintain 95% performance after six months of continuous use, outperforming metal alternatives in longevity.
- The pin surface can be polished to Ra ≤0.5 µm, ensuring smooth jetting and consistent droplet formation. This level of finish improves product quality in sensitive assembly lines.
- Tests show micro-droplet ejection accuracy within ±2% volume variation, which supports high-yield production in LED and IC packaging.
- The injector pin operates reliably at frequencies up to 1,000 Hz, providing stable dispensing even in rapid automated processes.

Surface Mount Adhesive Dispensing
✅Key Advantages
1. Tight volume control at speed — Achieves ±2% droplet volume at 600–1000 Hz. Polished Ra ≤0.5 µm impact surface reduces stringing and dot variability on fast SMT lines.
2. Extended wear life under fillers — Sustains >10 million cycles before measurable wear. Changeover frequency drops by ≥40%, stabilizing upstream placement accuracy through reflow.
3. Yield and rework improvement — Dot-to-dot CV held at ≤3%, which lifts first-pass yield by +1.5–3.0 pp. Rework time falls by 25–35% on adhesive stations.
✅ ️Problem Solved
A German EMS line dispensing glue for 0201 components recorded misalignment defects of 2.8% due to inconsistent dots and frequent pin wear. After switching to the ADCERAX® Zirconia Ceramic Piezoelectric Injector Pin, defects dropped to 0.8% and adhesive rework time decreased 32%. Tool change intervals moved from 1.5 weeks to 6 weeks, cutting stoppages across three shifts. Overall OEE improved by +6.2 points, with stable placement through reflow.

Conductive Silver Paste Jetting
✅Key Advantages
1. Abrasion resistance for Ag pastes — Vickers hardness > HV1200 limits diameter growth to <1 µm after 5 million Ag-paste shots. Jet stability is maintained despite high solids content.
2. Chemical robustness to binders/solvents — Mass loss <0.01% after 72 h in MEK/IPA blend; stable from pH 2–12. Surface integrity prevents pitting that triggers instability.
3. Lower clog incidence — Mirror polish reduces paste adhesion, cutting unplanned clogs by 50–70%. Droplet CV stays at ≤4% with viscosities 25–80 Pa·s.
✅ ️Problem Solved
A Japan LED module plant jetting 60–75 wt% silver paste faced clogs every ~20k shots and widening droplet variation. With ADCERAX® Zirconia Ceramic Piezoelectric Injector Pin, mean time-to-clog extended to ~220k shots and scrap fell from 4.5% → 1.2%. Unplanned maintenance dropped by 48 h/month, while paste waste reduced by 9.3 kg/month. Line takt was preserved during peak runs without sacrificing conductivity targets.

Conformal Coating of Electronic Boards
✅Key Advantages
1. Uniform film build — Coating thickness uniformity held to ±5 µm across 250×250 mm panels. Edge beading is reduced by >25% for clean keep-out zones.
2. Thermo-mechanical stability — Reliable jet path through 150–200°C cure zones with trajectory variance <1° under fixture vibration. Consistent windows on dense boards.
3. High-frequency selective patterning — Stable at up to 800 Hz, reducing overspray events by 30–45%. Repeatable film deposition over long runs.

User Guide for Zirconia Ceramic Piezoelectric Injector Pin
The following user guide provides essential recommendations for handling, operation, and maintenance of Zirconia Ceramic Piezoelectric Injector Pin. These guidelines help customers achieve stable performance, reduce unexpected downtime, and extend the service life of the product in demanding applications.
-
Handling and Storage
1. Always handle the injector pin with care and avoid dropping or collision with hard surfaces. Impact damage can cause micro-cracks that reduce performance stability.
2. Store the product in a clean, dry, and vibration-free environment to protect it from dust and moisture. Uncontrolled humidity increases the risk of corrosion and contamination during use.
3. Use protective gloves when handling to prevent oils and particles from adhering to the surface. Contaminants on the surface can compromise jetting accuracy in sensitive dispensing tasks.
-
Pre-Operation Preparation
1. Clean the surface of the injector pin before installation using approved solvents or ultrasonic cleaning. Residues left behind can disrupt fluid flow and affect droplet size control.
2. Inspect the product visually for chips, cracks, or scratches that could impact sealing and jetting. Even minor surface defects can lead to leakage during high-frequency cycles.
3. Verify compatibility with the dispensing fluid type before use. Chemical mismatch may reduce the lifespan of the injector pin in aggressive pastes or coatings.
-
In-Process Operation
1. Ensure stable alignment of the injector pin with the jetting valve during installation. Misalignment can generate inconsistent droplets and increase system wear.
2. Operate within the recommended frequency range to avoid excessive stress. Exceeding 1,000 Hz may accelerate wear and shorten the operational lifetime.
3. Monitor dispensing performance periodically during runs. Early detection of droplet variation allows timely intervention and prevents costly rejects.
-
Maintenance and Replacement
1. Schedule routine cleaning after every production cycle to remove adhesive or paste residues. Regular cleaning prevents clogging and ensures smooth fluid flow.
2. Replace the injector pin immediately if significant wear, erosion, or fracture is observed. Delayed replacement risks unplanned stoppages in high-throughput lines.
3. Keep records of usage cycles and replacement intervals. Tracking wear data improves predictive maintenance and helps optimize cost efficiency.
