If metal materials are wrapped around the antenna, the wireless signals will be reduced greatly, deteriorating the RF performance. As a dual in-line package (DIP), ZS2S is through-hole mounted onto the PCB. Sufficient space needs to be reserved for the antenna. -
Page 12: Packaging Information And Production Instructions
6 Packaging Information and Production Instructions 6.1 Mechanical Dimensions and Rear Solder Pad Dimensions Figure 6-1 ZS2S mechanical dimensions and rear solder pad dimensions 6.2 Production Instructions Preferentially use the wave soldering machine to solder the module, which is recommended for Tuya-developed modules that are through-hole mounted onto PCBs. - Page 13 Electroless nickel immersion gold (ENIG) is used for the PCBs. If the solder pads are exposed to the air for over three months, they will be oxidized severely and dry joints or solder skips may occur. Tuya is not liable for such problems and consequences. Throughout the production process, take electrostatic discharge (ESD) protective measures.
