5 ANTENNA INFORMATION 5 Antenna information 5.1 Antenna type ZT3L only uses the 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 16 / 23
6 PACKAGING INFORMATION AND PRODUCTION INSTRUCTIONS 6.4.1 PCB packaging diagram-SMT 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 • Baking equipment: – Cabinet oven – Anti-static heat-resistant trays – Anti-static heat-resistant gloves 2. Storage conditions for a delivered module are as follows: • The moisture-proof bag must be placed in an environment where the temperature is below 30°C and the relative humidity is lower than 70%. • The shelf life of a dry-packaged product is 6 months from the date when the product is packaged and sealed.
6 PACKAGING INFORMATION AND PRODUCTION INSTRUCTIONS and they are seriously oxidized for over 3 months. SMT is very likely to cause pseudo and missing soldering. Tuya is not liable for such problems and consequences. 6. Before using SMT, take electrostatic discharge (ESD) protective measures. 7.
