3. REQUIREMENTS
3.1. Safety
Do not stack component packages so high that the shipping containers buckle or deform.
3.2. Limitations
These connectors are designed to operate in a temperature range of -55° to 85°C [-67° to 185°F].
3.3. Material
The connector housing is made of glass-filled polyester. The contacts are made of phosphor bronze plated with
nickel; contact areas are plated with gold, and the tips are plated with tin-lead or matte tin.
3.4. Storage
A. Ultraviolet Light
Prolonged exposure to ultraviolet light may deteriorate the chemical composition used in the connector
material.
B. Shelf Life
The connectors should remain in the shipping containers until ready for use to prevent deformation to the
contacts. The connectors should be used on a first in, first out basis to avoid storage contamination that
could adversely affect performance.
3.5. Chemical Exposure
Do not store connectors near any chemical listed below as they may cause stress corrosion cracking in the
contacts.
Alkalies
Amines
Ammonia
Carbonates
Citrates
Nitrites
Phosphates Citrates
Sulfur Nitrites
Sulfur Compounds
Tartrates
3.6. PC Board (Motherboard)
A. Material and Thickness
The pc board material shall be glass epoxy (FR-4 or G-10). The pc board thickness range shall be
1.37 mm [.054 in.] min.
NOTE
Contact Product Information at the number listed at the bottom of page 1 for suitability of other board materials and
thicknesses.
i
B. Tolerance
Maximum allowable bow of the pc board shall be 0.03 mm [.001 in.] over the length of the connector.
Maximum allowable recycle of the pc board holes shall be three times.

C. Hole Dimensions
The holes in the pc board for the contacts must be drilled and plated through to specific dimensions. The
plating type and thickness and finished hole size must be as stated to provide unrestricted insertion. See

D. Layout
The holes in the pc board must be precisely located to ensure proper placement and optimum performance
of the connector. The pc board layout must be designed using the dimensions provided on the customer
drawing for the specific connector. A sample of the recommended pc board layout is shown in Figure 3.

3.7. Daughter Card Configuration
The circuit pads of the mating daughter card shall be made of gold. The daughter card thickness range shall be
1.37 through 1.78 mm [.054 through .070 in.].

The mating daughter card configuration must be in accordance with the dimensions and tolerances provided on
the customer drawing for the specific connector. A typical recommended daughter card configuration is shown in
Figure 4.

3.8. Connector Spacing
Care must be used to avoid interference between adjacent connectors and other components. The minimum
allowable distance between connectors to ensure proper mating is provided in Figure 5.
NOTE
This requirement is for manual placement of connectors. If robotic equipment is used, other space allowances will be
required for the grippers.

3.9. Connector Placement
CAUTION
Connectors should be handled only by the housing to avoid deformation, contamination, or damage to the contacts.
!
When placing connectors on the pc board, contacts must be aligned and started into the matching holes before
seating the connector onto the board. The force required to seat the connector onto the board can be calculated
by:
Number of connector positions x 35.6 N [8 lb] (maximum seating force per contact) =
connector seating force N [lb]

3.10. Polarization
The connectors are available with a polarization feature. These connectors are polarized to the mating daughter
card by the molded-in key. The daughter card must be slotted to accept the molded-in key. This prevents the
daughter card from being incorrectly inserted into the connector.
3.11. Keying
A key plug is available to insert into any of the inter-contact keying slots in the connector. The daughter card
must be slotted to accept the key plug. This prevents the daughter card from being incorrectly inserted into the
connector. The key plug must be inserted into the card slot with the flat end facing up, then fully seated. Keying
can be done before or after the connector is installed onto the pc board. See Figure 6.

3.12. Checking Installed Connector
The widest section of each contact must be inside the pc board hole. The housing must be seated on the pc
board not exceeding the dimension shown in Figure 7.

3.13. Daughter Card Mating and Unmating
CAUTION
!
When mating or unmating the daughter card, care should be taken to prevent longitudinal rocking of the daughter card
with respect to the connector. Angles greater than 3° could cause damage to the housing or misregistration of the
contacts and daughter card circuit pads.
The daughter card must be mated to the connector according to the following.
1. For connectors with a key plug, the keying slot of the daughter card must be aligned with the key plug. For
connectors with a molded-in key, the keying slot of the daughter card must be aligned with the molded-in key.
Refer to Figure 8, Detail A.
2. The daughter card must be inserted straight into the connector card slot until the card is fully seated. See
