I am working with the module electronic cooling on a heatsink for several electronic components, such as Cpu, DDR3, MOS, etc..
However, I am having difficulties with the manufacturers for the thermal resistance "junction to board".
On many website, I am able to find the "junction-to-case" and the "junction-to-ambiant" resistances but rarely the other one.
So, my question: is there a website (like matweb for instance) where we can find these values ?
Thank you all in advance.
Best regards, Seb.
