5 ANTENNA 5 Antenna 5.1 Antenna type ZTU uses only an onboard PCB antenna. 5.2 Antenna interference reduction To ensure the optimal Wi-Fi performance when the Zigbee module uses an onboard PCB antenna, it is recommended that the antenna be at least 15 mm away from other metal parts. To prevent an adverse impact on the antenna radiation performance, avoid copper or traces along the antenna area on the PCB.

6 PACKAGING INFORMATION AND PRODUCTION INSTRUCTIONS 6.5 Production instructions 1. Mount Tuya’s stamp hole package module with an SMT machine within 24 hours after unpacking and burning the firmware. Otherwise, the module must be packaged again under vacuum. The module must be baked before mounting.
6 PACKAGING INFORMATION AND PRODUCTION INSTRUCTIONS 4. Baking settings: • • • • • Baking temperature: 125±5°C Alarm temperature: 130°C SMT ready temperature: naturally cooling temperature: < 36°C The number of drying times: 1 Rebaking condition: The module is not soldered within 12 hours after baking. 5. Do not use SMT to process modules that have been unpacked for more than 3 months, because electroless nickel/immersion gold (ENIG) is used for PCBs and they are seriously oxidized for over 3 months.
