DISCO DAD3350 Precision Dicing Saw in Common Chase

Process: This is a high-precision automatic dicing saw used for cutting wafers and substrates into individual dies or pieces. It employs a high-speed diamond blade with programmable X/Y/Z control for accurate, repeatable cuts with minimal chipping or kerf damage.

Hardware: 1.8 kW high-torque spindle for fast blade rotation. X/Y axes with 260 mm travel range. Z-axis max stroke 32.2 mm with 0.00005 mm resolution. High-accuracy linear motors and vision alignment system. Programmable cutting speed (0.1–600 mm/s) and index step (0.0001 mm). Repeatability 0.001 mm.

Key Features:

  • Substrate size: Up to 8" wafers or 250×250 mm substrates
  • Spindle power: 1.8 kW
  • X/Y travel: 260 mm each axis
  • Z-axis: Max stroke 32.2 mm, resolution 0.00005 mm
  • Repeatability: 0.001 mm
  • Cutting speed: 0.1 to 600 mm/s
  • Index step: 0.0001 mm

Applications:

  • Wafer dicing into individual dies (Si, GaAs, SiC, glass, etc.)
  • Singulation of MEMS, photonic, or sensor devices
  • Cutting of ceramic or composite substrates
  • Precision sectioning for failure analysis or cross-section prep
  • High-volume or prototype die separation

Usage: Mount wafer/substrate on dicing tape/frame, align using vision system, load program (cut depth, speed, step size), set blade height, run automatic or step-by-step cuts, unload after completion. Clean blade/chuck after use. Follow SOP for blade change and safety.

Recipes & Data

  • Standard Cutting: Common parameters include:
 * Si wafers: Blade speed 30,000–60,000 rpm, feed rate 5–50 mm/s, depth 50–100 µm past substrate
 * Glass/ceramics: Lower feed rate (2–20 mm/s) to minimize chipping
 * Step size: Match die size (e.g., 1–10 mm streets)
  • Process Control: Perform test cuts on sample pieces. Check kerf width, chipping, and die quality via microscope/SEM. Adjust blade height/depth for full cut without damaging tape.
  • Notes: Use appropriate blade (hubbed or hubless) for material. Coolant (DI water) required. Secure tape/frame properly to avoid vibration. Blade dressing may be needed for new blades.
