Abstract
This invention discloses a method for debounding a magnetic head transducer from a head gimbal assembly, said magnetic head transducer being bounded to said head gimbal assembly by a solder ball, which is formed by solder ball bounding process, said method comprising: loading the head gimbal assembly on a fixture; directing a hot air gun to the solder ball of the head gimbal assembly and turning on the hot air gun; and taking away the magnetic head when the solder ball melts. The slider can be debounded by this method within 3-6s and very easy to design fixture and machine for production.
Claims5
A method for debounding a magnetic head transducer from a head gimbal assembly, said magnetic head transducer being bounded to said head gimbal assembly by a solder ball, which is formed by solder ball bounding process, said method comprising:
- loading the head gimbal assembly on a fixture;
- directing a hot air gun to the solder ball of the head gimbal assembly and turn on the hot air gun;
- and taking away the magnetic head from the suspension when the solder ball melts.
A method for debounding a magnetic head transducer from an electrical conductor, said magnetic head transducer having been bounded in an electrical connection with said electrical conductor by solder ball bounding process, said method comprising:
- directing a hot air gun to the electrical connection of the head gimbal assembly;
- turning on the hot air gun;
- and
- taking away the magnetic head transducer when the connection melts.
A method for debounding a read/write electronic circuitry of a disk drive from an electrical conductor, said read/write electronic circuitry having been bounded in electrical connection with said electrical conductor by solder ball bounding process, said method comprising:
- directing a hot air gun to a solder connection existing between said read/write electronic circuitry and said conductor;
- turning on the hot air gun;
- and
- taking away the magnetic head transducer when the connection melts
