Subject: Theta (jc) by Package Type
I am a Reliability Engineer performing stress analyses on medical and computer equipment. Stress analysis requires Theta (jc) as a data entry field. Many specification sheets do not have Theta (jc), C/W. Also, 217F Theta (jc) by package type is very inadequate. Is there a current Theta (jc) by package type available?

Just to note that the Theta jc values can often be found on the manufacturer's website, on either the parts spec sheet or sometimes as part of a general application note on thermal analysis or packaging reports.
