🔬 Our Component-Level Repair & Testing Workflow
How every faulty PCB is diagnosed, restored, and calibrated inside our laboratory:
Checking switching DC voltages (3.3V, 5V, 12V, 15V) to protect main MCU processor.
Desoldering burnt power transistors; installing OEM modules with high-temp heat paste.
Oscilloscope testing of serial communication wave, replacing degraded optocouplers.
Run under real compressor & fan motor load on our test rig before return courier.
⚡ Common Faults & Symptoms Restored by Our Engineers:
We repair the following component failures with a 90-day warranty:
High-voltage oscilloscope testing and precision semiconductor replacement for inverter microwave power generation boards. We replace paired high-voltage IGBTs, damping diodes, and resonant tank capacitors with genuine OEM specifications.
🏢 Supported Inverter AC & Appliance Brands:
We stock original OEM power modules, IGBTs, bridge rectifiers, and microcontrollers for all brands:
❓ Frequently Asked Questions
Common questions regarding diagnostic bench testing, pricing, and courier handling:
Can a burnt or dead inverter AC PCB be repaired instead of buying a new one?
Yes, over 95% of burnt inverter PCBs can be fully restored by replacing the IGBT/IPM power module, gate drivers, and optocouplers at 60-70% lower cost than purchasing a brand-new board.
How long does the PCB testing and component-level repair take in your laboratory?
Standard diagnostics, infrared micro-soldering, and oscilloscope full-load bench testing take 24 to 48 hours before return courier dispatch.
How does the doorstep courier pickup and delivery work?
Wrap your board securely in 3 layers of bubble wrap. Our courier partners (BlueDart, Delhivery, DTDC) collect the parcel from your doorstep with transit barcode tracking across 19,000+ pin codes in India.
Do you provide a warranty on repaired inverter boards?
Yes! Every repaired board includes our 90-day replacement and repair warranty for complete peace of mind.
