Fellow TechNetters:
Perhaps the third time is the charm:
Is there any data out there regarding the integrity of a Thermal Header Solder Attachment/Bottom Termination Component solder joint integrity over time. Most BTC that I have x-rayed exhibit some degree of voiding. Can the solder joint voiding degrade the solder connection to a point that it would result in a shorted device internally due to heat build. Is a solder joint a considered a Thermal Insulator?

Fellow TechNetters:
My original post last week did not generate any feedback. Therefore, I post again in hope of reaching more audience the beginning of the week. The holidays are over with and the serious work begins.
