Quality is the lifeline of electronics manufacturing. Rays-Power runs a full-chain quality system across design, manufacturing, validation and after-sales for both FFU group control systems and BMS products.
Design validation: every hardware revision ships a 50-unit pilot batch with full-load + burn-in testing; reliability processes such as inductor bonding; software strategies such as no auto-recovery after protection and lock after 3 failed starts prevent fault escalation.
Lifetime evaluation: in July 2026, the FFU controller completed 85/85 (85℃/85%RH) accelerated aging tests with equivalent-lifetime assessment reports, supporting warranty decisions.
After-sales loop: all returned units are analyzed, producing a "fault cause — repair record — improvement action" matrix, with improvements flowing back to next-generation design and production test standards.
Reliable products come from obsession with details and honest treatment of every field feedback.
