Industrial maintenance is the set of practices aimed at ensuring the reliable, safe, and efficient operation of machines, equipment, and production systems. It goes beyond simple fault correction: it involves prevention, planning, and continuous improvement.
There are three main types of maintenance:
- Corrective: performed after the failure
- Preventive: done based on schedules and cycles
- Predictive: based on data, sensors, and trend analysis
Maintaining is not just fixing — it’s avoiding downtime and ensuring performance with predictability.
🧩 Types of maintenance and their characteristics
| Type | Main characteristics | Example in testing context |
|---|---|---|
| Corrective | After failure. May cause unplanned downtime | Replacement of burnt relay or damaged power supply |
| Preventive | Periodic cycles or estimated usage | Monthly check of jig contacts |
| Predictive | Based on sensors, data, and trends | Failure analysis, abnormal cycle time |
⚙️ Commonly monitored items
- Power supplies, multimeters, PXI modules, relays, and switches
- Test benches, test jigs with actuators, presence sensors, and interlocks
- Cables, connectors, backplanes, and reference units
- Temperature, electrical noise, operation cycles, communication response
🔧 How AJOLLY Testing supports Maintenance
AJOLLY Testing integrates maintenance practices directly into its testing and production systems, focusing on predictability, traceability, and reliability.
🛠️ Digital preventive maintenance
- Electronic checklists with reminders by time or number of cycles
- Integration with MES or internal maintenance systems
- Automated verification of calibration, connectivity, and firmware
📊 Predictive monitoring
- Collection of metrics such as cycle time, FPY, CPK/PPK
- Automatic alerts for deviations or performance degradation
- Analysis of Pareto of failures and dashboards by station or equipment
📁 Technical traceability
- Complete record of interventions with date, reason, and solution applied
- History by serial number of jig, equipment, or test station
- Documentation compatible with ISO, IATF, GMP, FDA audits
With AJOLLY Testing, maintenance becomes a strategic part of the process, increasing availability, productivity, and confidence in testing.
