浙江东胜物联技术有限公司 Zhejiang Dusun electron Co., Ltd. 7 Antenna 7.1 Antenna type DSM-055 uses an onboard PCB antenna 7.2 Antenna interference reduction To ensure the optimal RF performance, it is recommended that the antenna be at least 15 mm away from other metal parts. Because DSM-055 is mounted to the main control panel through SMT, the placement location and manner of the PCB directly affect the RF performance. The following are placement positions recommended and not recommended.
浙江东胜物联技术有限公司 Zhejiang Dusun electron Co., Ltd. 8 Production Instructions Use an SMT placement machine to mount components to the stamp hole module that Dusun produces within 24 hours after the module is unpacked and the firmware is burned. If not, vacuum pack the module again. Bake the module before mounting components to the module.
浙江东胜物联技术有限公司 Zhejiang Dusun electron Co., Ltd. Baking settings: Baking temperature: 125±5℃ Alarm temperature: 130℃ SMT placement ready temperature after natural cooling:<36℃ Number of drying times: 1 Rebaking condition: The module is not soldered within 12 hours after baking. 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.
