DISCO Product Lines We Repair
Our engineers are trained on the full DISCO product range. Below are the major product families we service.
DAD (Dicing Before Grinding) Saw Series
Precision wafer dicing systems using diamond-coated blades for silicon, GaAs, and SiC wafers. Common issues include spindle bearing wear, blade chatter, coolant contamination affecting cut quality, and spindle speed encoder faults causing dimensional runout.
DFD (Dicing For Display) Saw Series
Specialized dicing equipment for large glass and brittle substrates used in display manufacturing. Frequent repairs involve vacuum chuck failure, pneumatic valve leakage, blade vibration damping system malfunction, and spindle frequency modulation electronics.
DGP (Dicing And Grinding Planer) Series
Integrated dicing and grinding systems for compound semiconductor wafers. Common faults include spindle imbalance, grinding wheel glazing sensor malfunction, coolant flow rate instability, and precision XYZ stage servo encoder drift.
GrindLap Grinding and Polishing Systems
Precision back-grinding and polishing machines for wafer thickness reduction and surface finishing. Typical repairs address motor overload faults, polishing pad pressure uniformity issues, coolant delivery nozzle clogging, and Z-axis load cell calibration drift.
Spindle Motor and Drive Electronics
High-speed brushless DC spindle motors (15,000-60,000 RPM) and dedicated servo drives for DISCO equipment. Repair issues include commutation sensor failure, bearing preload loss, drive phase imbalance, and encoder signal dropout causing speed regulation errors.
Coolant Recycling and Filtration Unit
Closed-loop coolant management systems maintaining cutting fluid cleanliness below 3 micron particle size. Common failures include pump cavitation, magnetic filter saturation, conductivity sensor malfunction, and pressure relief valve stiction causing coolant bypass.

Common DISCO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DISCO equipment arriving at our workshop.
- ✓Spindle runout exceeding 2-5 microns TIR — DISCO spindle bearings accumulate particulate contamination from cutting fluid or blade wear debris, causing radial play and axial float. Preload springs weaken after 5,000+ operating hours.
- ✓Blade chatter and dimensional inaccuracy in kerf width — DISCO diamond-coated blades experience micro-vibration when spindle speed feedback (tachometer or encoder) drifts, or when coolant flow rate drops below minimum threshold, causing inadequate chip flushing and blade loading.
- ✓Vacuum chuck pressure loss during wafer holding — DISCO vacuum chucks use porous ceramic pads that clog with wafer debris (silicon dust, gallium arsenide particles) or develop micro-cracks from thermal cycling. Vacuum pump inlet filters become saturated.
- ✓Servo drive fault code or axis position offset error — DISCO XYZ stage servo encoders accumulate dust, stage ballscrews develop play from wear, or servo amplifier tuning drifts due to thermal expansion in humid Indian factory environments. Mechanical backlash increases dimensional scatter.
- ✓Coolant recycling pump cavitation and pressure fluctuation — DISCO coolant pump cavitates when inlet filter clogs, coolant viscosity increases (from water loss in dry climates) reducing pump inlet pressure, or when suction lines develop micro-leaks. Pressure regulation valve springs lose preload.
- ✓Blade height sensing error or Z-axis load cell malfunction — DISCO load cell (strain gauge bridge in blade height sensor) develops zero-drift from thermal gradients, coolant seepage into sensor electronics, or mechanical shock from blade binding. Sensor cable shielding may corrode in humid conditions.

Frequently Asked Questions — DISCO Repairs
Do you repair DISCO equipment anywhere in India?+
Yes. Synchronics repairs the full DISCO product range — dicing saws, grinding machines, spindle motors, servo drives, coolant recycling systems, and all control electronics. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Gujarat, and all major semiconductor hubs. Equipment arrives at our Vadodara facility for repair, calibration, and precision testing. Turnaround is 10-15 business days for most DISCO repairs.
Does DISCO dicing saw spindle require special calibration after bearing replacement?+
Yes. DISCO spindles demand precision re-preloading and runout verification. After bearing replacement, our engineers use dial indicators to measure radial runout (target below 1 micron TIR) and axial preload (typically 20-50 grams for grinding spindles, 10-20 grams for dicing spindles). We also verify spindle speed regulation accuracy within +/- 100 RPM across the operating range. Incorrect preload causes blade chatter and dimensional scatter.
What is the typical lifespan of DISCO diamond dicing blades, and how do I know when to replace?+
DISCO diamond blades typically last 500-2,000 wafer cuts depending on substrate hardness (silicon ~1,500 cuts, SiC ~500 cuts). Indicators for replacement: kerf width increase beyond tolerance, visible blade edge chipping under optical inspection, or spindle power draw increase (>20% above baseline). Synchronics stocks DISCO OEM blades and can advise on blade life optimization based on your material mix and cutting parameters.
Can Synchronics provide on-site maintenance support for DISCO equipment at semiconductor fabs?+
Yes. Synchronics offers preventive maintenance contracts for DISCO equipment including quarterly spindle inspections, coolant analysis, encoder and servo diagnostics, and blade condition assessment. We can also provide on-call emergency repair support at your fab location in Gujarat, Tamil Nadu, and Maharashtra, with parts stocked locally to minimize downtime.
What is the cost of repairing a DISCO vacuum chuck ceramic pad, and how long does repair take?+
Vacuum chuck pad replacement typically costs INR 15,000-25,000 (OEM pad + labor + testing), with a 3-5 day turnaround. Cost varies based on chuck size and availability of replacement pads. We verify vacuum seal integrity and pump displacement post-repair. For urgent repairs, Synchronics can often expedite within 48 hours if parts are in stock.
How do I send my DISCO unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a DISCO drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on DISCO repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your DISCO unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
