During bakeout we recommend that you do not cover the external surface of the feedthrough with foil as the aluminium can rub off onto the ceramic and cause an electrical short. It is important not to exceed the feedthrough temperature and power ratings as this can damage the feedthrough, or cause vacuum leaks.
