3. REQUIREMENTS
3.1. 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 tool to
the header pins, and to protect the pc board and
header posts from damage. Design a pc board
support fixture for your specific needs.
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 102 Newtons (N)
[23 lb] per contact. For available application tools, call
PRODUCT INFORMATION at the number at the
bottom of page 1.
CAUTION
!
Over-driving of the header assembly could cause
damage to the pc board.
4. SEATING
1. Set seating height to the dimension shown in
Figure 3 (applicator shut height will equal the
seating height PLUS the combined thicknesses of
the pc board and pc board support).
2. Position header into pc board so that header
contacts are properly aligned to the board and
board support.
3. Insert header into pc board until the compliant
sections of the contacts are resting securely on,
but have not fully entered, the pc board.
4. Position appropriate seating tool into header,
making sure tool is bottomed on housing floor.
5. Center seating tool and header under the
applicator ram of the power source; slowly lower
ram until it just meets the seating tool. Verify the
alignment of the board support, pc board, header,
and seating tool.
CAUTION
!
Damage to the pc board, tool, or header may
occur if the wrong size tool is used, if seating
height is improperly set, or if tool is not
properly seated in the header before cycling the
applicator ram.
6. Cycle applicator ram according to instructions
for the power source. Check assembly for proper
seating, using the requirements in Figure 3.
NOTE
i
For additional information on inspection
requirements, refer to Application Specification
114-1075.
7. Remove pc board and seated header, or
reposition board and board support for seating
additional headers.
5. TOOL INSPECTION
Each seating tool is assembled and inspected before
shipment. We recommend that the tool be inspected
immediately upon arrival at your plant to assure that it
has not been damaged during shipment.
