What is importance of the reflow profile? I was reading the MPU6050 datasheet to understand all the type of errors that affect the accelerometer, after finding information on the Reflow Profile i look up on wikipedia the Reflow Soldering Definition

As a noob i can't understand the importance, initially i though it was correlated with the temperature effect on the accelerometer bias, but i was wrong. 

Why is important?

How do you read this values?(or when you use this data)
Reflow soldering is an assembly process for printed circuit boards (PCBs) in which surface-mount parts are placed on a PCB prepared with solder paste.  The solder is melted by heating in a temperature-controlled oven, which then electrically connects component leads to pads on the PCB.  ICs can be damaged by high temperatures/rapid changes in temperatures, so the thermal profile defines the acceptable limits on the temperature of the reflow to avoid damaging the component.
