PLC Repair Center Panchkula

Direct access to our primary diagnostics lab in Sector 20, Panchkula.

Local Support for Panchkula

Our main laboratory and workshop are located in Sector 20, Panchkula. Here, our engineers use specialized diagnostic tools, signature analyzers, oscilloscopes, and load testing benches. Local clients in Panchkula, Chandigarh, and Mohali can drop off their faulty VFDs, PLCs, and servo drives directly at our facility for immediate assessment and faster repair times.

Located at S.C.F-11, Ground Floor, New Grain Market, near Agro Mall, Sector 20, Panchkula. We are the regional repair center for Haryana and Punjab. Our Panchkula laboratory handles direct shipping, express transit networks, and quick turnaround processing to minimize the downtime of industrial sectors in Panchkula.

Our Premium 6-Step Component-Level Repair Process

How we restore electronic components to manufacturer specifications

Incoming Visual & Thermal Inspection

Every unit is registered and subjected to high-definition visual inspection and thermal scanning. We identify blown trace lines, scorched resistors, swollen capacitors, and signs of liquid ingress before applying any power.

In-Circuit Analog Signature Analysis

Using advanced Tracker/Signature Analyzers (such as Huntron Trackers), we test passive components (resistors, diodes, capacitors, inductors) and active ICs while in-circuit. This safe, power-off testing compares component electrical signatures against known-good standards.

Semiconductor Power-Stage Diagnostics

For VFDs and servo drives, we test the high-power rectifier and IGBT inverter stages. We check the gate-drive circuit paths, desaturation protections, and replace gate optocouplers to prevent catastrophic future failures.

Microscopic Solder & SMT Reflow

Using ISO-certified temperature-controlled desoldering stations, our IPC-trained technicians replace damaged components. We execute precision micro-soldering under stereo-zoom microscopes for multi-layer PCBs.

Controlled Bench & Load testing

After repair, units are powered on via variable-voltage current-limiting power supplies. We run full closed-loop tests under real load conditions—testing communication links, analog/digital feedback loops, and thermal efficiency.

Final QC Certification & Protective Coating

The repaired PCB is cleaned in an ultrasonic chemical bath to remove flux residues. We apply a high-grade conformal coating to protect against moisture, dust, and corrosive industrial oils before releasing the unit with our warranty.
