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.
(1) SMT placement equipment
i. Reflow soldering machine
ii. Automated optical inspection (AOI) equipment
iii. Nozzle with a 6 mm to 8 mm diameter
(2) Baking equipment
i. Cabinet oven
ii. Anti-static heat-resistant trays
iii. Anti-static heat-resistant gloves
