408-8810 Datasheet, PDF (2/3 Pages) Tyco Electronics – Read and understand these instructions before using the seating tool.

Seating Tools 91377-1 and 91378-1
408-8810
S it should have a flat surface with a cutout or
holes at least 28.5 mm [1.12 in.] deep (to allow
adequate clearance for the contacts)
3.2. Application Tooling
Power for the seating tool must be provided by
application tools (with a ram) capable of supplying a
maximum downward force of 890 Newtons (N)
[200 lb] per contact. For available application tools,
call PRODUCT INFORMATION at the number at the
bottom of page 1.
CAUTION
!
Over-driving of the connector could cause
damage to the pc board.
4. SETUP
When setting up equipment to seat the connector,
pay particular attention to the following:
S the seating tool must be matched to the
connector
CAUTION
!
If the seating tool and connector are mismatched
or are improperly aligned, damage could occur to
the tooling, connector, or both.
S the seating tool, connector, and application tool
ram must be properly aligned before cycling the
application tool
Set the seating height to the dimension shown in
Figure 2 (application tool shut height will equal the
seating height PLUS the combined thicknesses of the
pc board and support fixture). After seating, a gap of
no more than 0.10 mm [.004 in.] between the
connector housing and the pc board is allowed.
NOTE
i
Use the seating height as a reference starting
point. This height may need to be adjusted to
obtain the amount allowed (maximum of 0.10 mm
[.004 in.]) between the housing of the connector
and the pc board.
5. USING THE TOOL
1. Place the pc board on the support fixture.
2. Place the connector on the pc board so that the
contacts are aligned and started into the matching
holes in the pc board.
3. Position the seating tool onto the connector so
that the bottom surface sits flat on the connector.
4. Center the top of the seating tool (with the
connector) under the ram of the application tool.
Slowly lower the ram until it just meets the seating
tool. Verify alignment of pc board support, pc
board, connector, and seating tool.
CAUTION
!
Damage to the pc board, seating tool, or
connector may occur if the seating tool is not
properly inserted into the connector before
cycling the application tool.
5. Cycle the application tool to seat the connector
on the pc board. Then retract the ram, and remove
the seating tool from the connector.
