How to control the humidity while producing PCB for SMD RGB LEDs?

I plan to produce large quantities of PCBs for the LEDs. But I have come across comments that they are very sensitive to the humidity. How do the manufacturers usually control the humidity?

Reduce the amount of process time and strictly regulate how long it is left in the air after it is molded.
Prior to production, raw materials that are suitable for hygroscopicity should undergo baking and dehumidification. The baking time and temperature should be determined based on the characteristics of the material.
Semi-products are kept in cabinetsthat are sealed against moisture, and the production site’s temperature and humidity are regulated.
Dehumidify and bakethe product.
Pack the product in a vacuum.
Before using, products that have been stored for a long period should be baked and dehumidified.
