🛠 Chip-Level Repair of Industrial SMPS Units Over time, SMPS units can fail due to power surges, overheating, component fatigue, or manufacturing defects. While standard repairs often involve replacing the entire unit, chip-level repair focuses on diagnosing and restoring functionality at the component and circuit level—resulting in cost-effective and sustainable solutions. ✅ Key Areas in Chip-Level SMPS Repair: Power Stage Diagnosis: Testing and replacing damaged MOSFETs, IGBTs, or switching transistors Identifying short circuits or dead shorts in the high-voltage section PWM Controller & Logic IC Repair: Replacing damaged PWM ICs, voltage regulators, or startup circuits Troubleshooting overvoltage/undervoltage protection circuits Capacitor & Diode Testing: ESR testing of electrolytic capacitors and ceramic caps Replacing failed Schottky diodes or rectifiers Transformer & Inductor Analysis: Inspecting for insulation damage, winding failures, or magnetic saturation PCB & Solder Trace Repairs: Micro-soldering damaged traces, connectors, or burnt tracks Cold solder rework on high-heat stress areas Control & Feedback Loop Repair: Replacing op-amps, TL431 reference ICs, and opto-isolators Calibrating voltage/current regulation feedback circuits ⚙️ Benefits of Chip-Level SMPS Repair Services 💸 Cost-effective vs full unit replacement 🔄 Sustainability through reuse of existing hardware 🧰 Precise fault isolation for mission-critical industrial systems 🕒 Faster turnaround when new units are unavailable or obsolete 🛡️ Preservation of compatibility with legacy equipment 🚀 Applications Across Industries Chip-level SMPS repair is vital in: Industrial automation & control panels Textile machinery & CNC machines Medical instrumentation Telecom & server infrastructure Power supplies for PLC, HMI, and servo drives
