In March 2026, VintechME successfully handled a repair case for a Thermal Shock Test Chamber for a major electronics components manufacturer in Vinh Phuc. With a highly experienced engineering team, VintechME quickly resolved the issue, ensuring the equipment returned to stable operation and met its original technical specifications.
1. Overview of the Issue
During operation, the customer observed abnormal behavior:
- The chamber could only increase temperature and was unable to perform cooling
- The thermal shock cycle was interrupted and could not meet testing requirements
- The compressor was still operating normally
Impact:
- Affected thermal durability test results of components
- Disrupted QA/QC testing schedules
- Impacted production and delivery timelines
2. On-Site Inspection & Diagnosis
Upon receiving the request, VintechME engineers:
- Arrived promptly at the customer’s factory
- Conducted a full system inspection, including:
- Refrigeration system (compressor, expansion valve, refrigerant)
- Heating system
- Temperature sensors
- Control system (controller)
Diagnosis result:
- Root cause identified as controller failure, leading to loss of control over the cooling cycle
Although the compressor was running:
- It did not receive proper control signals
- Failed to activate correct hot–cold switching cycles
→ Resulting in loss of thermal shock functionality
3. Optimal Repair Solution
Based on extensive experience with thermal shock chambers (2-zone and 3-zone), VintechME implemented the following solution:
✔️ Controller Replacement
- Selected a compatible controller (PID / PLC / HMI depending on configuration)
- Ensured:
- High accuracy
- Long-term stability
- User-friendly operation
✔️ System Configuration & Calibration
- Reconfigured all critical parameters:
- Hot zone / cold zone temperatures
- Transfer time
- Cycle time
- Synchronized with original OEM specifications
✔️ System Interlock Verification
- Ensured proper coordination between:
- Compressor
- Heater
- Damper / Basket mechanism
- Optimized thermal shock cycle performance according to testing standards
4. Testing – Handover – Acceptance
After repair completion, VintechME performed:
- Multiple full-cycle tests (hot ↔ cold)
- Evaluation of:
- Temperature transition speed
- Temperature stability
- Deviation from setpoint
Results:
- ✅ Stable operation restored
- ✅ Fully meets original technical requirements
- ✅ Successfully accepted by the customer on-site
