Our Process

How We Work

1

Free Inspection & Quotation

Send us your unit via courier or WhatsApp the model. We inspect it free of charge and send you a fixed-price quote within 24–48 hours.

2

Component-Level Diagnosis

Our engineers trace faults at the IC and component level using oscilloscopes, thermal imaging, and original schematics — not just board swaps.

3

Quality Repair

We use genuine or compatible components from trusted suppliers. Every soldered joint is inspected under magnification.

4

Full-Load Testing

Each repaired PLC is tested under real working conditions — power cycles, I/O verification, communication tests — before it leaves our workshop.

5

Warranty & Return

Repairs come with up to 6 months warranty. We document the work and ship the unit back insured.

FAQ

How long does a typical PLC repair take?+

Most PLC repairs are completed within 3–7 working days from the time we receive the unit. Urgent jobs can be prioritized — let us know on WhatsApp.
