The insertion tool assemblies listed in Figure 1 are
used to seat a Z–PACK TinMan header assemblies
(reference part number 1469660–1). These header
assemblies have eye–of–needle compliant pin
contacts to allow solderless pc board installation.
Reasons for reissue of this instruction sheet are
provided in Section 8, REVISION SUMMARY.
Each insertion tool consists of a holder, insert plates
(quantity based on number of connector columns),
and two dowel pins. Some insertion tools also include
a special insert plate(s). The dowel pins hold the
insert plates in place. See Figure 1.
The holder provides a surface to accept the force
applied by the application tool to seat the header
assembly onto the pc board. During seating, the
insertion tool sits inside the header assembly and the
insert plates prevent the contacts from pushing out of
the header assembly.
A pc board support must be used to provide proper
support for the pc board and to protect the pc board
and header assembly from damage. The board
support fixture must be designed for specific needs
using the following recommendations:

it should be at least 25.4 mm [1 in.] wider than
the pc board
it should have a flat surface with a cutout of at
least 28.5 mm [1.12 in.] deep (to allow
adequate clearance for the header assembly)

Power for the insertion tool must be provided by
application tools (with a ram) capable of supplying a
downward force of 44.5 N [10 lb] per contact.
For available application tools, call PRODUCT
INFORMATION at the number at the bottom of
page 1.
When setting up equipment to seat the header
assembly, pay particular attention to the following:
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 insertion, a gap of
no more than 0.10 mm [.004 in.] between the header
assembly standoffs and the pc board is allowed.
i
the insertion tool must be matched to the
header assembly
the insertion tool, header assembly, and
application tool ram must be properly aligned
before cycling the application tool

damage to the pc board.
If the insertion tool and header assembly are
mismatched or are improperly aligned, damage
could occur to the tooling, header assembly, or
both.
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 standoffs of the header
assembly and the pc board.
