Note: The default dimensional tolerance is ±0.3 mm. If a customer has other requirements,
clearly specify them in the datasheet after communication.
6.3 Production Instructions
1. Use an SMT placement machine to mount the stamp hole module that Tuya produces
onto the PCB 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 it
onto the PCB.
