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 Ammonia Citrates Phosphates Citrates Sulfur Compounds

Amines Carbonates Nitrites Sulfur Nitrites 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.

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.

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.

3.5. Socket Insertion

A. Hole Size Inspection

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).

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.

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.

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.

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.

Power Units

A power unit is an automatic or semi–automatic device used to assist in the application of a product.

Power unit includes the power source used to supply the force or power to an applicator.

Flat-Rock Tooling

Flat–rock press–in tooling may be used for mass insertion of the sockets into the plated–through holes

on the pc board. Removable carrier strips on 2.54 [.100] centerlines may be used with this type of mass

insertion. Flat–rock press–in tooling is customer designed.

Vibratory/Vacuum System

Commercially available, fully automatic mass loading machines which will accommodate a

vibratory/vacuum system may be used for application of this product. The assembly table (1437513–1)
