A burn in process is when you first change semiconductors they are cold of course you want to bring the temp up as slow as possible to avoid cracking the core it's like pouring cold water on a hot glass it cracks! so when I change semiconductors I allow them to run and monitor the temp on all of them to make sure they won't fail for my customers........
