WBR1 Datasheet Figure 6-4 Layout of the PCB to which WBR1 applies 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.
WBR1 Datasheet iii. 2. Anti-static heat-resistant gloves Storage conditions for a delivered module are as follows: (1) The moisture-proof bag is placed in an environment where the temperature is below 30°C and the relative humidity is lower than 70%. (2) The shelf life of a dry-packaged product is six months from the date when the product is packaged and sealed. (3) The package contains a humidity indicator card (HIC). Figure 6-5 HIC for WBR1 3.
WBR1 Datasheet or solder skips may occur. Tuya is not liable for such problems and consequences. 6. Before SMT placement, take electrostatic discharge (ESD) protective measures. 7. To reduce the reflow defect rate, draw 10% of the products for visual inspection and AOI before first SMT placement to determine a proper oven temperature and component placement method. Draw 5 to 10 modules every hour from subsequent batches for visual inspection and AOI. 6.
