CNI Repair Services India

Yes, absolutely. Synchronics Electronics repairs the complete CNI laser product range - diode drivers, fiber-coupled modules, temperature control units, power supplies, wavelength stabilization boards, and alignment systems. We operate pan-India service with door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all major industrial cities. All repairs are processed at our Vadodara, Gujarat facility where our 180+ engineers maintain CNI-specific test benches and calibration equipment.

CNI laser driver board repairs typically require 5-7 working days depending on component availability and complexity of circuit diagnosis. Photodiode feedback circuit repairs and calibration are fastest (3-4 days), while complete power supply module rebuilds may take 8-10 days. Synchronics maintains stock of common CNI components (photodiodes, TEC modules, connectors, laser drivers) to minimize wait times. We offer expedited 48-hour turnaround on critical production downtime situations for automotive and pharmaceutical clients.

Yes. Synchronics possesses CNI wavelength calibration protocols and maintains calibrated reference photodiodes traceable to Indian Standards for laser metrology. We recalibrate WSB series boards to maintain wavelength accuracy within ±0.05nm, ensuring your laser marking and spectroscopy systems meet original equipment tolerance. Recalibration includes thermal cycling verification (-10°C to +50°C) and 8-hour stability testing with full data documentation.

Synchronics maintains strategic stock of CNI spare parts including laser driver ICs, photodiode modules, thermoelectric cooling elements, high-voltage capacitors, and fiber-optic connectors. For common failures (capacitor replacement, photodiode swaps, TEC module substitution), we source matched components and complete repair without requiring customer-supplied parts. For rare or discontinued CNI modules, we coordinate with authorized distributors and can expedite sourcing to minimize production downtime in your facility.

Synchronics employs comprehensive CNI test protocols: laser power stability testing across 0-100% current range with <2% variation, wavelength drift measurement over 8-hour thermal cycles using calibrated spectrometers, photodiode feedback linearity verification, and EMC stress testing to 10V/m field strength simulating factory floor conditions. All CNI repaired equipment is returned with detailed test certificates documenting output power, wavelength accuracy, thermal response, and protection circuit functionality - essential documentation for precision manufacturing environments.

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.

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.

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.

Yes. If we cannot repair your CNI 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.
