Things to consider before baking components
Moisture sensitive devices are packaged in a moisture barrier antistatic bag with a desiccant and a moisture indicator card which is sealed.

According to IPC, Moisture/reflow sensitivity classification for plastic Integrated circuit (IC) SMDs,floor life out of the bag for MSL 3 devices is 168 hours. So, you can mount them without baking even after 6 days of floor life.
