Baking of "ESP32-WROOM-32D"
Posted: Wed Jun 22, 2022 6:15 am
Hello.
I'm JK Park
I am contacting you because I have an inquiry regarding ESP32-WROOM-32D.
After purchasing 650 ESP32-WROOM-32D materials in reel packaging, we used 7 of them.
The packaging was opened when using 7 pieces, so it is currently in the same condition as the attached picture (more than 2 months have elapsed since opening)
Baking is required to use all the remaining quantities.
Through Datasheet, it was confirmed that MSL Level: 3, thickness: 3.10±0.15
Based on IPC/JEDEC J-STD-033D, we confirmed that it is stated that it should be baked at a low temperature of 40 degrees for 79 days.
- If I bake at a low temperature with a reel, I would like to inquire about the temperature/time. (Do I really have to bake at 40 degrees for more than 79 days?)
I'm asking because it seems difficult to bake at 125°C for 48 hours due to the large quantity.
Thank you.
