Dear Jose-san,
Thank you for your special support.
In the HDC 1080 of the customer, there is an error in the accuracy of the output,
I am looking for ways to solve this.
As one of the factors, we believe that the reflow temperature is attributable to it.
I have two questions.
①
The customer implements the HDC 1080 with the attached reflow profile.
The peak temperature is low compared to TI's recommendation, but if this temperature is low,
Is there a possibility that the moisture absorption of the device is insufficient and the IC absorption value varies after mounting?
②
This IC absorbs moisture because it is a capacitive coupling type, but even with an IC that was deviated by about 5% in humidity precision,
by removing moisture againIs it possible to think that the accuracy of humidity returns to 1-2% based on it?
If so, does the same phenomenon occur with the heater function of the HDC1080?
Best,Regars.
