Customized Alumina Ceramic Slice for Insulation, Spacing, and Fixturing

Alumina Ceramic Slice Applications

• Power electronics module assembly (IGBT/relay/heatsink isolation)

  ✅ Key Advantages

  1. Thickness tolerance controlled to ±0.05 mm ensures uniform clamp pressure across 20+ modules.
  2. Edge radius ≤0.2 mm reduces crack initiation under torque loads by up to 30%.
  3. Polished Ra 0.1 µm surfaces improve thermal paste contact, lowering resistance variation below 5%.

  ✅ Problem Solved

  In a relay assembly line, uneven shim thickness caused 12% of modules to fail breakdown tests. After switching to alumina ceramic slices with ±0.05 mm tolerance and 0.2 mm edge radius, rework dropped by 80% and QA pass rates stabilized at 99.3%. Lot-coded IDs simplified tracking, cutting inspection time by 15%.

• Laboratory fixtures & thermal carriers

  ✅ Key Advantages
  1. Flatness ≤0.05 mm across a 50 mm slice area maintains sample planarity in thermal exposure.
  2. Polished Ra 0.05 µm faces reduce particulate release, keeping contamination levels under 50 ppm.
  3. Laser-cut slots ±0.1 mm tolerance enable repeatable airflow and fixture alignment.

  ✅ Problem Solved

  A research lab found polymer carriers warped 0.2 mm after 10 cycles, leading to misaligned samples and repeat experiments. By adopting alumina ceramic slices with ≤0.05 mm flatness and low Ra polished surfaces, warping was eliminated and contamination was reduced by 40%. Repeat experiments fell sharply, saving two full test weeks per quarter.

• Automation & Machine Tooling shims & wear interfaces in assembly lines

  ✅ Key Advantages

  1. Hardness >13 GPa keeps gauge distances stable over 10,000 press cycles.
  2. Traceable laser IDs reduced tool set-up verification time from 20 min to 5 min.
  3. Bow limit ≤0.03 mm prevented tilt-induced dimensional errors in stack-ups.

  ✅ Problem Solved

  An automotive line experienced 7% dimensional rejects due to stack-up drift in metal shims. After replacing them with alumina ceramic slices with hardness >13 GPa and bow ≤0.03 mm, reject rates fell below 1%. Traceable IDs also cut set-up checks by 75%, improving uptime and ensuring tool calibration consistency.

Alumina Ceramic Slice Usage Instructions

• Use

  a. Always handle alumina ceramic slices with nitrile or latex gloves to prevent fingerprints, oil, or ion contamination.
  b. Place slices only on lint-free, anti-static mats; avoid rough or metallic surfaces that may scratch polished faces.
  c. Do not apply point loads or force directly on edges; always use distributed pressure clamping to avoid micro-cracks.
  d. Follow the recommended torque sequence during assembly to ensure stress is evenly distributed across the slice.
  e. For thin slices (<0.5 mm), use carrier trays or backing plates during handling to minimize flexural stress.

• Storage

  a. Keep slices in original interleaf paper, vacuum pouches, or cavity trays to maintain separation and avoid stack rubbing.
  b. Store in a dry, dust-free environment with stable temperature (15–30 °C) and controlled humidity (<60% RH).
  c. For long-term inventory, add desiccant bags or silica gel packs and use sealed vacuum packaging to prevent moisture uptake.
  d. Avoid direct sunlight, corrosive chemicals, or strong airflow that can introduce dust and accelerate surface degradation.
  e. Maintain batch separation with clear labeling to ensure traceability of thickness tolerance and lot numbers.

• Cleaning

  a. Use neutral detergent or isopropyl alcohol (IPA) with lint-free wipes for safe surface cleaning.
  b. Air-dry slices in a particle-controlled area; avoid compressed air unless filtered and oil-free.
  c. For polished surfaces (Ra ≤0.1 µm), avoid abrasive cleaners or pads, which can compromise flatness.
  d. Ultrasonic cleaning may be applied for unpolished slices but should be avoided for thin or edge-sensitive parts.
  e. After cleaning, store slices in interleaf or cushioned trays to avoid scratches from re-contact.

• Common Mistakes & Fixes

  a. Edge impacts → Use chamfered edge options and cushioned packaging; train operators to handle with carriers.
  b. Thickness mix-up → Specify laser-engraved IDs or lot codes; always separate storage by labeled trays.
  c. Surface scratches → Request polished face orientation and interleaf separation; prohibit sliding slices against each other.
  d. Moisture exposure → Use vacuum-sealed bags with desiccants; avoid storing in humid or unsealed cabinets.
  e. Improper clamping → Adopt torque-limited drivers and soft fixture pads; prevent over-tightening that causes micro-cracks.
  f. Static charge accumulation → Use anti-static mats and grounded trays to minimize electrostatic attraction of dust.

Alumina Ceramic Slice FAQ

1. Q: How do I request a quotation for alumina ceramic slice?
   A: Send drawing or size list, thickness and tolerance, surface finish (Ra), edge style, quantity (sample/batch), packaging preference, and target lead time. This enables an accurate alumina ceramic slice quote response.
2. Q: What drives alumina ceramic slice price differences?
   A: Tighter thickness bands, polished faces, micro-hole geometry and edge-chip limits increase cycle time and yield requirements, affecting unit price.
