1. INTRODUCTION
This specification covers the requirements for application of AUGAT HOLTITE Sockets. These manually
applied or reel–mounted machine applied solderless spring sockets are designed to be contained within the
barrel of a plated–through hole. The design allows the socket and plated–through hole to form a zero–profile
component socket which provides an interconnect for a broad range of electronic parts and components. The
sockets are available in a variety of different series and sizes based on printed circuit (pc) board hole diameter.
They are also available normally on mylar strips which can be reeled on custom socket patterns for ease of
application.
When corresponding with personnel, use the terminology provided in this specification to facilitate your
inquiries for information. Basic terms and features of this product are provided in Figure 1.

3. REQUIREMENTS
3.1. Storage
A. Ultraviolet Light
Prolonged exposure to ultraviolet light may deteriorate the chemical composition used in the socket.
B. Shelf Life
The sockets should remain in the shipping containers until ready for use to prevent deformation to the
sockets. The sockets should be used on a first in, first out basis to avoid storage contamination that could
adversely affect signal transmissions.
C. Chemical Exposure
Do not store sockets near any chemicals listed below, as stress corrosion cracking in the sockets may
occur.
Alkalies
Amines
Ammonia
Carbonates
Citrates
Nitrites
Phosphates Citrates
Sulfur Nitrites
Sulfur Compounds
Tartrates
3.2. Material
All sockets are made of beryllium–copper with gold, tin/lead, or tin plating.
3.3. PC Boards
A. Material and Thickness
1. Board material will be glass epoxy (FR–4, G–10).
2. Board thickness shall be 0.75 [.030] minimum for all socket sizes except for 12P which is used in a
1.27 [.050] minimum thick pc board.
Contact the Product Information number listed at the bottom of page 1 for suitability of other board
materials or thicknesses.
B. PC Board Hole Dimensions
The socket holes in the pc board must be precisely drilled to ensure proper placement and optimum
performance of the socket. The drilled holes must be on 2.54 [.100] centerlines (minimum). The
dimensions provided in Figure 2 must be observed when preparing a pc board for AUGAT HOLTITE
Sockets.

CAUTION
Holes should be drilled from the component insertion side of the pc board, whenever possible, to avoid creating
drill-exit burrs on the press-fit portion of the through-hole.
CAUTION
Finished hole tolerances should NOT be maintained by drilling over-sized holes and then plating down to the correct
size, because plating alone will not create the compressive forces necessary to retain the socket over time and
temperature ranges. Drilling undersized holes may introduce problems such as excessive socket insertion forces,
board warpage, and crazing around the hole.

The appropriate AUGAT HOLTITE Socket is selected based on the cross–section size of the leads to be
inserted. The diameter of a round lead or the diagonal of a rectangular lead determines the appropriate socket.
The table in Figure 3 lists which socket should be used for certain common lead sizes.

AUGAT HOLTITE Sockets
3.5. Socket Insertion
A. Hole Size Inspection
114-13033
Using the red NO–GO gage, part number 5–1437514–1, end of the tool provided in the AUGAT HOLTITE
Printed Wiring Contact Kit, check to ensure the hole dimensions are correct. If not, rework may be
necessary or socket selection may need to be re–checked.
B. Insertion
Sockets are inserted into the pc board using a spring loaded hand tool, a pneumatic hand tool system,
flat–rock press–in tooling, or commercially available vibratory/vacuum systems using fully automatic
machines. Two different tips may be used for socket insertion into the pc board. The blue tip is used for
the 5P, 14P, and 27P series sockets. The other insertion tip is white and is used for the 6P, 8P, and 12P
series sockets. Refer to Section 5, TOOLING for specific related tooling part numbers.
3.6. Checking Installed Socket
Once the socket is installed, verification may be made to a correct installation according to the information and
dimensions provided in Figures 2 and 4.
A. Referee Test
Inspection may reveal that some of the hole diameters are at the high limit of the tolerance. If this marginal
condition occurs, a “referee test” should be performed to determine if the holes are suitable for 5P
AUGAT HOLTITE Socket insertion.
Selectively load the sockets into the suspect holes and perform a push–out test using an adequate axial
force gauge (e.g., a hand held CHATILLON Force Gauge). Force should be applied to the socket fingers
only in an axial direction. Socket retention forces will vary with each application due to differences in
socket population density, substrate materials, and number of PC layers. The minimum acceptable
push–out force for all 5P AUGAT HOLTITE Sockets is [4 lbs.] (conforming to MIL–S–83505/6).
t
B. Insertion Verification
Tyco Electronics suggests verifying that the sockets have been loaded into all of the desired locations.
This procedure could be accomplished visually or with any type of available automatic non–contacting
inspection system.
For visual inspection, place a light source under the pc board an examine the holes form above. A small
point of light indicates the socket is present. A large point of light indicates the socket may be missing. The
light pattern may be compared to a chart showing socket locations.

For the alternate method, use an opaque inspection template drilled in a pattern matching the socket
locations. There should be no large points of light with the template in place. A loading mask used in
conjunction with a mass loading machine will serve this purpose.
3.7. Wave Soldering Consideration
Both AUGAT HOLTITE Sockets and soldered components may be loaded on a pc board. However, either the
AUGAT HOLTITE Sockets or their respective plated through holes must be masked to avoid being filled with
solder during wave soldering. If the socket can be contained within the pc board, it may be loaded first, and
then masked with heat–resistant tape or liquid solder mask prior to soldering to other components. If the socket
would protrude through the pc board, the appropriate plated through holes should be masked and wave
soldering performed first. Then, the masking is to be removed, and the AUGAT HOLTITE Sockets may be
installed. See Figure 5.

3.8. Repair/Replacement
If a socket has been damaged, it must be removed and replaced with a new one. In order to remove a
damaged socket, lay the circuit board flat, circuit fingers up on a suitable backing material such as a dense
foam board or pad. Place a drill blank on top of the socket fingers, making sure it is properly aligned, and tap it
gently with a small hammer until it releases from the pc board. See Figure 6.

It may be necessary, if the socket fingers are damaged, to break off the individual finger elements before
removing the socket barrel using the previous technique. Installation of a single replacement socket can then
be accomplished.
4. QUALIFICATIONS
These sockets are qualified to MIL–S–83505/6D. However, they are not required to be Recognized by
Underwriters Laboratories Inc. (UL); or Certified to CSA International.
5. TOOLING
Tyco Electronics has existing tooling and tooling concepts for applying these sockets. Part numbers of
available tooling and the applicable instructional material for each is provided in Figure 7.
S
PC Board Support
A pc board support must be used to prevent bowing of the pc board during insertion of the sockets. It
should have a flat surface with holes or a channel large enough to receive the sockets during installation.
S
Hand Tool
The insertion portion of the tool is designed to remove the sockets from their respective carrier cards
and selectively insert them into the plated–through hole on the pc board. Individual pressing and seating
is then accomplished using the correct insertion tip and hand tool.
S
Pneumatic Hand Tool System
The pneumatic tooling system is designed to individually seat the sockets after they have been inserted
into the plated–through hole on the pc board. The tip of the pneumatic hand tool is inserted into the
socket and the impact button is depressed. The socket is accurately seated into the plated–through
hole. Pressure adjustments and variable tip sizes on the pneumatic hand tool allow this system to work
with any size socket.
