1) Tolerance for peak profile temperature (TP) is defined as a supplier minimum and a user maximum.
2) Depending on package thickness. For details please refer to JEDEC J-STD-020D.
3) Tolerance for time at peak profile temperature (tP) is defined as a supplier minimum and a user maximum.
Note: All temperatures refer to topside of the package, measured on the package body surface.
Number of reflow cycles: 3
