I have several separate identical PCBs with identical ICs on them. It's fairly critical for this application that all the IC's are synchronized in regards to temperature. E.g. if one increases by 1 deg, they should all increase by 1 deg.
There's two solutions i'm thinking of. One is to simply enclose everything in an enclosure, and create an oven like effect, but this may also create cooling issues.
The other is to use a heat pipe that is snaked across the PCBs and thermal pasted to each of the IC's. I assume that this will help synchronize the temperatures as the heat pipe should stabilize to the mean temperature?
Is there anything else I should be looking at doing?
