of electrical performance during the test, the samples were
removed from the chamber for connect resistance measurements
after 250, 500, 750, and 1000 h. The thermal shock
test was also performed using an Espec Temp. & Humid
SH-240 chamber, and the specimens were subjected to 1000
heating and cooling cycles from −15 to 100 ◦C. The holding
time at each temperature extreme was 60 min and the
