HDC3021: Best practices when soldering

Dane Lennon
Prodigy 40 points
Part Number: HDC3021

Tool/software:

Hi there,
We are in the development phase of a project where we are going to integrate your HDC3021 sensor into a humidity sensor. We are seeking advice on best practices when soldering this chip to a rigid FR4 PCB. We note in your documentation that you have listed what you should NOT do, but you don't mention any recommended soldering processes (eg vapor phase, hot air reflow, radiated etc), solders to use, fluxes to use, and conformal coating. Could you please tell us what is safe to use (not just what isn't safe to use).

Thank you in advance

    Hello Dane,

    Thank you for your interest in our product. Since there are so many products on the market it is difficult to make a recommendation, however I will check with our team if we have any resources for that.

    For soldering/rehydration tips, I would consult pages 36-38 of the datasheet as it contains some information about soldering flows and rehydrations processes.


    Hope this helps!
