3.2. PC Board Support Fixture (Customer Supplied)
A pc board support must be used to provide proper
support for the pc board and alignment of the seating
tool to the header, and to protect the pc board and
header contacts from damage. Design a pc board
support fixture using the recommendations in
Instruction Sheet 408-6927.
4. SEATING
1. Set the seating height to the dimension shown in
Figure 2 (applicator shut height will equal the
seating height PLUS the combined thicknesses of
the pc board and pc board support).
2. Position the header onto pc board so that the
header contact posts are properly aligned with the
holes in the pc board and pc board support.
3. Insert the header onto the pc board until the post
sections of the contacts are resting securely on, but
have not fully entered, the pc board.
4. Position the appropriate seating tool into the
header, making sure that the seating tool is
bottomed on the housing floor.
NOTE
i
For Seating Tools -1 (not keyed), make sure that
the grounding arrow is pointing toward the end row
of ground blades of the header. 
5. Center the seating tool and header under the
applicator ram of the applicator; slowly lower the
ram until it just meets the seating tool. Verify the
alignment of the pc board support, pc board,
header, and seating tool.
CAUTION
!
Damage to the pc board, seating tool, or header
may occur if the wrong size seating tool is used, the
seating height is improperly set, the grounding
arrow (for Seating Tools -1) is oriented incorrectly,
or the seating tool is not properly seated in the
header before cycling the ram.
6. Cycle the applicator. Check the header for proper
seating using the requirements in the Application
Specification 114-13020.
7. Remove the pc board with the seated header or
reposition the pc board and pc board support to
seat additional headers.
CAUTION
!
Do not use damaged or defective headers. 
