I need to measure temperature of HVAC inlet and outlet. I am looking for customized strips for connecting the chip as shown in the attachment. Appreciate your assistance.
Is it going to be placed within the air flow? or is it going to be attached to some other guy? If so, rememeber the exposed pad is the less thermal resistant path from the heat to go into the die. So, it the back of your flex is also a exposed pad you may want to attach it to your heat source.
In any case, please don't forget to place your decoupling caps as close as possible to the IC as stated on the datasheet.
I am going to place it in between the ducts i.e. within the air flow. I understand that back side i.e exposed end is thermally sensitive. Hence, I will be going for rigid PCB and cable to extend the connection rather than flexible PCB. Hence, all the circuitry will be with 2.1 cm X 1 cm area.
While going for rigid, are there any other consideration which needs to be considered?
Appreciate your assistance.
