Reliability Verification Capability
Proven Under Stress
A complete environmental and aging test suite validating designs against real-world extremes.
Vibration Test
Check connections and assemblies under mechanical vibration.
High & Low Temp Operation
Verify powered operation in high- and low-temperature environments.
Temperature Step Cycling
Assess durability through repeated, controlled temperature changes.
High & Low Temp Storage
Evaluate unpowered assemblies after exposure to temperature extremes.
Salt Spray Test
Assess corrosion resistance under salt-laden conditions.
Steady-State Damp Heat
Evaluate performance under sustained heat and humidity.
Drop Test
Assess resistance to impact during handling and transport.
Aging Test
High-Temperature Aging
Expose assemblies to elevated temperatures over time to reveal latent defects and assess operating stability.
Burn-in (Powered Aging)
Run powered assemblies under controlled loads to identify unstable performance and early-life failures.
Early Failure Screening
Review test results and isolate units with early-life defects before they move on to shipment.
F & Q
Quality Questions
Standards, inspections, reliability and documentation — how we prove quality.
Factories operate under ISO 9001-based quality controls, with IATF 16949 and ISO 13485 processes available for automotive and medical programs.
Solder paste inspection, placement verification, AOI, X-Ray where required and SPC checkpoints are linked to each lot before release.
We can coordinate thermal cycling, humidity, vibration, solder-joint and electrical stress testing through our in-house and qualified partner laboratories.
Typical shipments include certificates of conformity, inspection summaries, electrical test results, material-lot traceability and customer-specific PPAP records when required.
We run containment, root-cause analysis and 8D/CAPA workflows, then feed corrective actions back into the control plan and production process.
