Abstract

Disclosed is an HDD (Hard Disk Drive) part carrier for load/unload ramp. The said ramp is a molded part, and required a lot of 1/100 mm unit dimensions. This HDD part is also a required cleaning process. This carrier protects external damage from "Just after molding process" to "Just before assembling into HDD" via cleaning process. Then, draining structure and very few out gas levels are required.

Load/Unload Ramp Carrier

      Disclosed is an HDD (Hard Disk Drive) part carrier for
load/unload ramp.  The said ramp is a molded part, and required a lot
of 1/100 mm unit dimensions.  This HDD part is also a required
cleaning process.  This carrier protects external damage from "Just
after molding process" to "Just before assembling into HDD" via
cleaning process.  Then, draining structure and very few out gas
levels are required.

      Fig. 1 shows said ramp and sensitive locations, which are (1)
to (3).  These areas are protected from any contacts during
transportation and cleaning process.  Figs. 2 and 3 show three pins
for each ramp in the carrier.  One of them, marked as (7), passes
said ramp hole, which is marked (4).  The other two pins, marked as
(8) and (9) are very closed to (5) and (6), in Figure (1).  They
prevent said ramp rotation.

      At the bottom of pin (7), a small raised area is shown as (10)
in Fig. 2.  This area prevents direct contact of "Ramp and Carrier,
and helps draining after the cleaning process.  Figs. 2 and 3 show a
great deal of window at the bottom and side surfaces for draining.

      The ramp and carrier contact for a very long
time.  Consequently, just after molding, when the ramp's surface
temperature is high, the carrier material requires a very low out-gas
level at a long period and high temperature.
