3.2. Application Tooling
Power for the seating tools must be provided by a
machine capable of supplying a downward force of
89 Newtons (N) [20 lb] per contact. Manual Electric
Servo Press (MEP 6T) 2--1399500--5 and Bench Top
Electric Servo Presses (BMEP 3T) 1--1399400--5 and
(BMEP 5T) 2--1399401--4 are available for these
seating tools. For information on the presses, visit the
press--fit assembly equipment website at
http://tooling.tycoelectronics.com/pressfit.asp.
4. SEATING
1. Set 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 support.)
2. Position the connector onto the pc board so that
the contacts are properly aligned with the holes in
the pc board and the holes or slots in the pc board
support fixture. See Figure 2.
3. Sit the connector onto the pc board until the tips
of the contacts are resting securely on, but have
not fully entered, the holes in the pc board.
4. Position the seating tool onto the connector with
the slanted surface oriented as shown in Figure 2.
5. Center the seating tool and connector under the
applicator ram, and slowly lower the ram until it just
meets the seating tool. Verify the alignment of the
pc board support fixture, pc board, connector, and
seating tool.
CAUTION
!
Damage to the pc board, seating tool, or
connector may occur if seating height is
improperly set, if the pc board is not properly
positioned with the seating tool, or if the seating
tool is not properly seated on the connector
before cycling the applicator ram.
6. Cycle the applicator ram according to
instructions for the application tooling.
7. Remove the pc board with the seated connector,
and check the connector for proper seating
according to the following:
a. the widest section of each contact is inside its
intended pc board hole
b. the connector is seated on the pc board with
the seating height given in Figure 2.
