By integrating various sensors and AI algorithms, Tortai Technologies enables devices to recognize different treatment scenarios and automatically select optimal treatment modes.
Trend 4: Ultra-High Reliability Design – Fortifying the Foundation of Medical Safety
The fundamental distinction between medical devices and consumer electronics is that any failure can directly endanger patient lives. Therefore, ultra-high reliability is a core requirement in medical PCBA design.
Tortai Technologies adheres to the IPC-A-610J CLASS III standard for electronic acceptance, the highest quality level in the electronics industry. In producing motherboards for brain function physiotherapy devices, they implement a comprehensive quality control system, ensuring a product yield rate exceeding 99.5%.
Robustness in Harsh Environments:Medical PCBAs must operate stably under demanding conditions like temperature variations, humidity, and electromagnetic interference. Through rigorous EMC (Electromagnetic Compatibility) design, Tortai Technologies ensures device stability across various environments.
Comprehensive Safety Mechanisms:Multiple safety mechanisms, including fault self-detection, safety isolation, and redundancy design, ensure that a single component failure does not lead to system failure. Tortai Technologies employs a dual safety circuit design in its medium-frequency pulse physiotherapy device PCBA, effectively preventing overload risks.
A case study from a top-tier hospital in Shanghai showed that after equipping 3,200 hospital devices with medical-grade PCBAs produced by Tortai Technologies, downtime caused by electrical failures decreased by 92%. A leakage protection PCBA module certified to IEC 61010 blocked 427 risks over a 7-year service period, with a false alarm rate of only 0.7%.
