2. DESCRIPTION (See Figure 1)
Each seating tool kit consists of a seating tool and a wall support. The seating tool and wall support are also
available separately. The seating tool has cutouts (two located on each side) to accept the protruding part of
the standoffs of the cage assembly. The wall support must be installed into the port(s) of the cage assembly.
The top of the seating tool provides a surface to accept the force applied by the application tool to seat the
product onto the pc board. During seating, the back and sides of the seating tool protect the cage assembly
from damage. The wall support supports the individual port(s) of the cage assembly.
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 to protect the pc board and
product from damage. The support fixture must be designed for specific needs using the following
recommendations:
 it should be at least 25.4 mm [1 in.] longer and wider than the pc board
 it should have flat surfaces with holes or a channel large enough and deep enough to receive any
protruding components of the product
3.2. Application Tool
Power for seating tools must be provided by an application tool (with a ram) capable of supplying a downward
force of 44.5 N [10 lb-force] per contact. For available application tools, call PRODUCT INFORMATION at the
number at the bottom of page 1.
CAUTION
Over-driving of the product will deform parts critical to the quality of the connection. Maximum force occurs prior to the product
bottoming on the pc board.
4. SETUP
When setting up equipment to seat the product, pay particular attention to the following:
 the seating tool must be matched to the product
CAUTION
If the seating tool and product are mismatched or are improperly aligned, damage could occur to the tooling, product, or both.
 the wall support must be properly installed, and the seating tool, product, and application tool ram must be
properly aligned before cycling the application tool
1. Set tool seating height to the dimension shown in Figure 2 (application tool shut height will equal the
tool 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 cage assembly standoffs and the pc board is
allowed.
NOTE
Use the tool 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 cage assembly and the pc board.
2. Slide the wall support into the port(s) of the cage assembly until the wall support is secure.
5. SEATING (Figure 2)
NOTE
For a cage assembly using a surface mount connector, the connector must be mounted on the pc board BEFORE seating the
cage assembly.
1. Place the pc board on the support fixture.
2. Orient the seating tool over the product so that the back is aligned with the back of the product. Then
lower the seating tool onto the product, making sure that the cutouts slide over the protruding
components of the product, until the seating tool bottoms on the top of the product.
