Thermal Clad Long Term Reliability
New materials undergo a rigorous 12 to 18 month qualification pro-
gram prior to being released to the market.
In state-of-the-art laboratories and test facilities, Bergquist performs
extensive testing on all their thermal materials for electrical integrity.
Bergquist utilizes stringent development procedures.The lab facilities at
Bergquist are U.L. cer tified and manufacturing facilities are ISO
9001:2000 certified.

Chamber Ovens – Over 3000 cubic feet (85 cubic meters)
of oven capacity is dedicated to long term thermal bias age
testing. The ovens take material to temperatures above T g .
At selected intervals, samples are removed and tested to
verify material integrity.

Thermal Clad Reliability
Extensive qualification testing consists of mechanical property valida-
tion, adhesion, temperature cycling, thermal and electrical stress. To
validate long term reliability, electrical testing is performed at selected
intervals to 2000 hours where final evaluation is completed.
To ensure consistent product performance with manufactured materi-
als, we couple the up-front qualification test with regular audits. Audits
include physical, electrical and thermal property tests.
