1. INTRODUCTION
This specification covers requirements for application of Micro--Strip Board--to--Board Plug and Receptacle
Connectors designed for printed circuit (pc) board applications. The connectors have in--row contact spacing
on 1.27 mm [.050 in.] centers and row--to--row contact spacing on 2.54 mm [.100 in.]. There are designs to
accommodate 40 thru 240 contact positions. The connectors are designed for manual placement on pc boards.
Figures 1 and 2 provide connector features and terms used throughout this specification. Use these terms
when corresponding with TE Connectivity Representatives to facilitate assistance.
1.1. Plug Connectors
Plug connectors are vertical configurations. There are designs with ACTION PIN* contacts which provide a
force fit and eliminate the need for soldering, and there are designs with straight contact tines for solder
applications. Some of the solder--type connectors have two retentive contacts at both ends and on both sides
of the connector, that will help hold the connector in the pc board prior to soldering, and some have only
straight contact tines where customer hold--down will be used to hold the connector in place. One version has
mounting flanges. All plugs have two polarizing slots that match polarizing ribs in the mating receptacle. A
single rib on the housing indicates the number 1 pin position and two ribs on the housing indicate the number 2
position. See Figure 1.
1.2. Receptacle Connectors
Receptacle designs are available in vertical and right--angle designs with various solder tine lengths. The
right--angle connectors have mounting flanges and the vertical connectors do not. Each housing has two
polarizing ribs that match the polarizing slots in the plugs. A single marker on the housing indicates the
number 1 contact position and a double marker indicates the number 2 position. See Figure 2.

2.2. Customer Assistance
Reference Product Base Part Number 536254 and Product Code 3591 are representative of Micro--Strip
Board--to-- Board Plug and Receptacle Connectors. These numbers are used in a customer service network to
access tooling and product application information. This service is provided by your local TE Representative or,
after purchase, by calling the Tooling Assistance Center or the Product Information number at the bottom of
page 1.
2.3. Engineering Drawings
Customer Drawings for specific products are available from the responsible Engineering Department via the
service network. The information contained in the Customer Drawing takes priority if there is a conflict with this
specification or any other technical documentation supplied by TE.
2.4. Specifications
Product Specifications 108--17 and 108--1272 describes performance tests for these connectors.
2.5. Technical Publications
The following list includes available instruction sheets (408--series) that provide assembly procedures for
product, operation, maintenance and repair of tooling; and customer manuals (409--series) that provide setup,
operation, and maintenance of machines.

2.6. Manuals
Manual 402--40 is available upon request and can be used as a guide in soldering solder--type connectors. The
manual provides information on various flux types and characteristics along with commercial designations and
flux removal procedures. A checklist is included in the manual as a guide for information on soldering
problems.
3. REQUIREMENTS
3.1. Product Materials
Micro--Strip Connector housings are constructed of high--temperature thermoplastic. The receptacle and plug
connector contacts are made of copper alloy. Contacts are underplated with nickel. They have tin plating on the
solder tines and gold plating in the contact interface area.
3.2. Storage
Connectors are packaged and shipped in either protective anti--static tube or tray containers. They should
remain in the containers until ready for use to prevent physical damage to the housings and contacts. The
connectors should be used on a first--in/first--out basis to avoid storage contamination that could adversely
affect signal transmissions and solderability of the solder--type connectors. If a receptacle has a tine organizer,
it should remain on the contacts through the entire process of handling and final assembly.
3.3. Polarization
The receptacle connectors have two polarizing ribs with a tapered lead--in and the plug connectors have two
mating slots to prevent reverse mating.
3.4. Circuit Identification
Plug and receptacle housings have a single rib molded into the sidewall at one end to indicate the number 1
position. They have two ribs on the other side to indicate the number 2 position.

3.5. Mating Dimensions
Full mating of connectors is essential to assure a good connection. The required mating dimensions for the
various connector styles are provided in Figure 3. Note that the connectors are shown unmated for clarity, but
the dimensions given are for fully mated connectors. Contact the Tooling Assistance Center or the Product
Information number listed on page 1 for other mating dimensions.

3.6. Mating/Unmating Technique
The pressure used to mate and unmate connectors must be applied evenly and in--line with the connectors to
prevent deformation or other damage to the contacts, housing, or surrounding board components. The knifing
or peeling action of applying force to one end or one side must be avoided. The end--to--end and side--to--side
limitations are provided in Figure 4.

NOTE
i
Guards will help prevent uneven disengagement of connectors which could damage the contacts, housing, or other
components on the pc board. The preferred location is one at each of the four corners of the pc board; however, a
guard can be centered at each end of the first (polarized row of contacts in the connector. Guards can be mounted to
either the plug or receptacle pc board. Suggested guard designs and required spacing are provided in Figure 5.
