Abstract
A method of degassing a disk drive component including heating the drive component to a temperature ranging from about 70.degree. C. to 250.degree. C.; subjecting the drive component to vacuum pressure during heating, the vacuum pressure having a first pressure and a second pressure; and monitoring the vacuum pressure to determine the level of degassing of the disk drive component.
Claims24
A method of degassing a disk drive component, said method comprising the steps of:
- a) heating the drive component to the service temperature of the component, said temperature ranging from about 30.degree. C. to 250.degree. C.;
- b) subjecting the drive component to vacuum pressure during said heating, wherein said vacuum pressure comprises a first pressure and a second pressure;
- and
- c) monitoring said vacuum pressure to determine the level of degassing of the disk drive component.
