5 Industries Where FADOS Board Testers Are…

The Board Repair Challenge in India

India’s electronics repair and maintenance industry faces a fundamental challenge: as PCBs become denser, multi-layered, and increasingly populated with BGA and fine-pitch components, traditional multimeter-based troubleshooting becomes impractical. A modern automotive ECU or industrial PLC has thousands of components across 8–12 layers, finding a single faulty component with a multimeter is like finding a needle in a haystack.

FADOS circuit board testers from CBT Electronic solve this by using VI curve tracing, a power-off comparison technique that identifies faulty components in seconds without requiring schematics, functional knowledge, or powered test fixtures. Here are five industries in India where FADOS is making a measurable impact.

1. Automotive: ECU and Powertrain Module Repair

Modern vehicles contain 30–100+ electronic control units. When an ECU fails out of warranty, the OEM repair path is often “replace the entire module”, costing ₹15,000 to ₹2,00,000 depending on the module. Component-level repair using FADOS can recover 60–80% of these boards at a fraction of the replacement cost.

Common automotive FADOS applications:

Engine Control Module (ECM) repair
Transmission Control Unit (TCU) diagnostics
Body Control Module (BCM) troubleshooting
ABS/ESP module fault isolation
Instrument cluster repair

The FADOS 9F1’s built-in programmable power supply is particularly valuable for automotive work, it can simulate the vehicle’s 12V/24V supply while the IR sensor detects overheating components, a common failure mode in automotive electronics exposed to engine bay temperatures.

2. Aerospace & Defence: Depot-Level Maintenance

India’s defence establishments maintain radar systems, communication equipment, avionics modules, and weapon system electronics that may be decades old, often without available schematics or OEM support. FADOS enables depot-level repair by comparing faulty boards against a reference unit, bypassing the need for documentation that may be classified, unavailable, or obsolete.

Defence-specific advantages:

No schematic required, compare against any known-good reference board
Reference signatures stored in encrypted databases for security
Power-off testing eliminates risk to sensitive military electronics
FADOS MUX enables batch testing of spares inventory

GSAS has delivered FADOS systems to multiple Indian defence R&D laboratories and depot-level repair facilities.

3. Industrial Automation: PLC and Drive Repair

Manufacturing downtime caused by a failed PLC or variable frequency drive costs Indian factories ₹50,000–₹5,00,000 per hour depending on the production line. Replacing the entire board takes days (import lead time); component-level repair with FADOS can restore operation in hours.

Industrial automation applications:

PLC CPU and I/O module repair
Variable Frequency Drive (VFD) power stage diagnostics
HMI/SCADA controller board troubleshooting
Servo drive and stepper driver repair
Power supply module fault isolation

The FADOS 7F1 portable unit is ideal for industrial field service, maintenance technicians carry it to the factory floor, connect to the failed board in-situ, and diagnose without removing the board from the cabinet.

4. Medical Device Service: Third-Party Repair

India’s growing third-party medical equipment service industry relies on board-level repair to maintain diagnostic imaging systems, patient monitors, laboratory analysers, and surgical equipment. OEM service contracts are expensive; component-level repair using FADOS provides an alternative revenue stream for independent service organisations.

Medical device repair scenarios:

Patient monitor main boards and power supplies
Ultrasound system processor boards
X-ray generator control electronics
Laboratory analyser interface boards
Infusion pump controller boards

Traceability is critical in medical device repair, FADOS software generates fault reports with VI curve data, component identification, and repair actions taken, providing the documentation trail required for regulated medical device maintenance.

5. Electronics Manufacturing: Production QC

Electronics manufacturers and contract assemblers use FADOS with the MUX multiplexer for automated incoming inspection and end-of-line testing. The MUX scans 96 test points per board automatically, comparing each against a golden reference and generating pass/fail reports.

Production applications:

Incoming PCB inspection (verify boards from contract manufacturers)
End-of-line functional test augmentation
Post-rework verification
Warranty return analysis and failure classification
Process quality monitoring (trend analysis of VI curve deviations)

FADOS + GSAS Digital Microscopes: The Complete Repair Workflow

Many GSAS customers pair their FADOS tester with a GSAS digital microscope, the FADOS identifies the faulty component through VI curve analysis, then the microscope provides the magnification needed for precise rework on fine-pitch packages. The GSAS 2422 4K autofocus microscope is the most popular pairing, providing 230x magnification with measurement overlay for BGA and QFN rework.
