8. Precautions for use
The Wi-Fi & Bluetooth module exposed in the air (the core board inside the
module or the whole composed of the core board and the base board) shall at least
meet the service environmental conditions of general consumer electronic products,
including but not limited to:
Working temperature: - 20 ~ 85 ℃
Storage temperature: - 20 ~ 85 ℃
Working humidity: 0~95 %RH
Storage humidity: 0~98 %RH
Tolerance - 20 / + 85 ℃, every 2h a cycle, thermal shock, under the impact of the
cycle of at least 20 don't appear dysfunction or performance degradation, no
significant tin crack phenomenon.
When working for a long time, the temperature rise of the circuit components
should meet the requirements of their own specifications.
To simulate the transportation process and home application scenarios, the module
should be able to withstand a certain degree of mechanical impact and drop.
Through certain protective means, Wi-Fi & Bluetooth module can have higher
environmental adaptability.When designing a Wi-Fi & Bluetooth module, the
performance, size and process margin required for the implementation of protection
measures should be reserved.
FCC Certification Requirements.
