5 ANTENNA INFORMATION 5 Antenna information 5.1 Antenna type ZT5 only uses the onboard PCB antenna. 5.2 Antenna interference reduction To ensure the optimal Zigbee 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 6.3.1 PCB footprint diagram-SMT 6.4 Production instructions 1. For the modules that can be packaged with the SMT or in an in-line way, you can select either of them according to the PCB design solutions of customers. If a PCB is designed to be SMT-packaged, package the module with the SMT. If a PCB is designed to be in-line-packaged, package the module in an in-line way. After being unpacked, the module must be soldered within 24 hours.
6 PACKAGING INFORMATION AND PRODUCTION INSTRUCTIONS needs to be put into the drying cupboard where the relative humidity is not greater than 10%; or it needs to be packaged again under vacuum and the exposure time needs to be recorded (the total exposure time cannot exceed 168 hours).
6 • • • • PACKAGING INFORMATION AND PRODUCTION INSTRUCTIONS There is no humidity indicator card (HIC) in the packaging bag. After unpacking, circles of 10% and above on the HIC become pink. The total exposure time has lasted for over 168 hours since unpacking. More than 12 months have passed since the sealing of the bag. 4.
