Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What is the purpose of a burn-in test? **A**: Burn-in testing accelerates aging to identify early-life failures in motherboards. By subjecting boards to elevated temperatures and voltage variations, latent defects are revealed before the boards are integrated into final products, reducing field failures and warranty costs. ### Q: What are the key specifications to verify before purchase? **A**: Key specifications include temperature range (0–70 °C), temperature uniformity (±2 °C), accuracy (±0.5 °C), maximum power output (2–5 kW), voltage regulation (±0.5%), chamber capacity (10–50 boards), cycle time (30–120 hours), and communication interfaces (RS-485, Ethernet). Always confirm these values with the manufacturer for your specific model. ### Q: What standards does the equipment reference? **A**: The equipment references IEC 60529 for ingress protection (IP54) and ASTM A240 for stainless steel 304 chamber material. These standards are procurement references; they do not guarantee certification of the specific unit. Verify compliance with the supplier. ### Q: What are the installation requirements? **A**: The machine requires a three-phase 380 V AC ±10%, 50/60 Hz power supply. It operates in non-condensing environments with 20–80% relative humidity. Floor space needed is 2.5–4.5 m², and weight ranges from 800–1500 kg. Ensure the site meets these requirements. ## 6.
