Device for assembling base and main board assembly for hard disk drive

An apparatus, comprising:

• a base of a hard disk drive, said base having a surface with at least one position determining projection and at least one stopper projection;
• and
• a board unit being coupled to said base, said board unit having a surface forming at least one orifice, said at least one position determining projection of said base being inserted into the at least one orifice of said board unit when said board unit is moved in a first direction with the surface of said base facing toward the surface of said board unit, said board unit being moved in a second direction to bring said board unit into contact with said at least one stopper projection of said base, the moving of said board unit in the second direction being performed with the surface of said board unit positioned to face toward the surface of said base, the second direction being perpendicular to the first direction.

An apparatus, comprising:

• a first unit having at least one guiding unit;
• and
• a second unit having at least one positioning unit and at least one stopping unit, said at least one positioning unit being engaged with said at least one guiding unit when said first unit is moved in a first direction toward said second unit, said first unit being moved in a second direction to bring said first unit into contact with said at least one stopping unit, the first direction being substantially perpendicular to the second direction, said first unit corresponding to a board of a computer system.

An apparatus, comprising:

• a first unit having at least one guiding unit;
• and
• a second unit having at least one positioning unit and at least one stopping unit, said at least one positioning unit being engaged with said at least one guiding unit when said first unit is moved in a first direction toward said second unit, said first unit being moved in a second direction to bring said first unit into contact with said at least one stopping unit, the first direction being substantially perpendicular to the second direction, said first unit corresponding to a base of a hard disk drive, said second unit corresponding to a board unit.

An apparatus, comprising:

• a first unit having at least one guiding unit;
• and
• a second unit having at least one positioning unit and at least one stopping unit, said at least one positioning unit being engaged with said at least one guiding unit when said first unit is moved in a first direction toward said second unit, said first unit being moved in a second direction to bring said first unit into contact with said at least one stopping unit, the first direction being substantially perpendicular to the second direction, said at least one guiding unit corresponding to an orifice formed by said first unit, said at least one positioning unit being engaged with said at least one guiding unit when said at least one positioning unit is inserted into said at least one guiding unit.
