Hi Tom

Do you know what temperature rating a standard FR4 board have?


Best Regards

Henrik,

There is a chart available from IPC that discribes all the temperature ratings for all FR4 materials with different weaves and thicknesses. I'll try to dig it up and post it for you.

Iv'e attached the Environmental Properties of Common Dielectric Materials.

I found this "Worst Case Use Environments" data.
