We are evaluating the Apalis dual core industrial temp SOM. I have provided the datasheet to our mechanical engineer. He has these additional questions:
Can you request from the supplier the 2 thermal resistances listed below? Often these are not on the datasheet, but the manufacturer can provide them. With this information we could then track the actual junction temperature of the SOM in the thermal model.
- Junction-to-Board (theta Jb)
- Junction-to-Case (theta Jc) – They do list on their datasheet a Junction-to-Top with a typical and max value. Not sure if this is considered the Junction-to-Case, which is the common terminology.
