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 Tyco Electronics 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.

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. Lift Evenly 5_ (Max) 3_ (Max) 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.

Drying Air drying of cleaned connectors is recommended. Temperature for the connectors should not exceed --55 to 105_C [--67 to 221_F]. Degradation of the housings could result from extreme temperatures. 3.11. Repair Connectors with damaged solder--type contacts can not be repaired. The solder must be removed and the entire connector replaced. Connectors with damaged ACTION PIN Contacts can be repaired by removing the damaged contact(s) and replacing it using the tool kit provided in Paragraph 5 and the appropriate replacement contact, of which there are three: offset, straight, and bus. When extracting or inserting contacts, make sure you use a backup plate suitable to support the housing with a slot or hole deep enough to receive the contact. NOTE i The extraction of contacts removes some of the pc board material. We recommend three times as the maximum number of times that a contact should be extracted and replaced in any one cavity. 4.
