ANP AMP INCORPORATED CUSTOMER HOTLINE APPLICATION 114-6036 Harrisburg, Pa. 17105 1 800 722-1111 SPECIFICATION REV | REASON ENGINEERING RELEASE DATE CHAMP* PRINTED 12-14-88 CIRCUIT BOARD APPROVAL MOUNTED CONNECTORS ROGER FLAHERTY 1. INTRODUCTION This specification covers the requirements for application of AMP* CHAMP printed circuit (PC} board mounted connectors. The connectors are available in shielded and unshielded versions and are designed for right-ang!e-, vertical-, and edge-mount applications. The follawing are product features and terms that will be used throughout this specification. The illustrations repre- sent the available mounting options and show unshielded connectors for simplicity (plug and receptacle, shielded and unshielded are essentially the same). NOTE Alf dimansions in this specification are given in inches and have a decimal tolerance of +.005 and an angle tolerance of +2 unless otherwise specified. Metric equivalents frm) can be obtained by multiplying the given dimension by 25.4. .072 Centerline {Typ) =] .085 RIGHT-ANGLE-MOUNT Genterline CONNECTOR (Typ) Contact Tines (Typ) EDGE-MOUNT CONNECTOR VERTICAL-MOUNT CONNECTOR Fig. 1.

Customer Drawings Customer Drawings for specific products are available from the responsible AMP Engineering department. The information on Customer Drawings takes priority if there is a conflict with this specification or with any other techni- cal documentation supplied by AMP Incorporated. 3.5. Product Number and Product Code Product Part Number 552725 and Product Code 1252 are assigned to the AMP CHAMP PC board connector product line. Use of these numbers will identify the product line and expedite your inquiries through an AMP service network established to help you obtain product and tooling information. Such information can be obtained through a local AMP Representative (Field Sales Engineer, Field Application Engineer, etc.) or, after purchase, by calling the CUSTOMER HOTLINE at the top of Page 1. 3. REQUIREMENTS 3.1. Printed Circuit Board 4. Material The board should be composed of glass/epoxy material, use of less dimensionally stable material may pre- sent problems when inserting the components. B. Thickness The connectors may be installed on .062- to .125-in.-thick PC Boards for vertical- and right-angie-mount connectors and on .062-in.-thick PG Boards for edge-mount connectors. Board thickness may vary depend- ing upon application, however, terminal length becomes important for wave solder operations. A recommended minimum of .040 terminal should protrude through the PC Board. PC Boards are divided into three categories, Class A, Class B, and Class C, depending on hole location tolerances (see Figure 2). HOLE LOCATION TOLERANCES RELATED BOARD SIZE CLASS A CLASS B CLASS C Greatest dimension is less than +.006 +.004 +.002 12,00 inches. Greatest dimension is greater than +.008 +.006 +.004 12.00 inches.

Polarizing By its very design, the connector is polarized. The keystone configuration of the mating face prohibits the acciden- tal inversion of a mating connector. 3.5. Methods of Attaching Connector to PC Board The connector should be secured to the PC Board prior to soldering. This can be done by using any of the following methods: A. Commercially Available Hardware Most connectors are to be attached to the PC Board with commercially available screws, washers, and nuts, rivets, or similar devices. The hardware should ba attached prior ta soldering and soldered in place when the solder posts are soldered. B. Boardilocks Some connectors include boardlock features that contain two gripping shoulders which lock into position as the solder posts are inserted into the PC Board.

Fastening Hardware CHAMP PC BOARD MOUNTED CONNECTORS Hardware such as screwlock kits, bail lock kits, and CHAMP-LOK* kits are available to secure mated unshielded connectors. Shielded connectors are available in kit form and will accept standard fastening hardware or the con- necitors are available in preassembled form with fastening hardware also preassembled.

Soldering A. Flux Selection The connector solder tails and attaching hardware (if applicable} must be fluxed prior to soldering with a medium active rosin base flux or a medium to highly active organic flux. Selection of the proper flux will depend on the type of PC Board and other components, if any, mounted on the board. Additionally, the choice of flux will have to be compatible with the flow solder line, manufacturing, and safety requirements. B. Cleaning Removal of fluxes, residues, and activators is mandatory. Cleaning procedures are dependent upon the type of flux used on the solder line. c. Orying When drying cleaned assemblies and PC Boards make certain that temperature limitations of -55 to 105 C are not exceeded. Excessive temperatures may cause housing degradation. D. Soldering Guidelines AMP Corporate Bulletin 52 is available upon request and can be used as a guide in soldering. This bulletin provides information on various flux types and characteristics along with the commercial cesignation and flux removal procedures. A checklist is attached to the bulletin which is intended to serve as a guide fer obtaining information on soldering problems. Special Filter Connector This receptacle connector filters out unwanted frequencies by capacitive parallel circuits to ground. Fig. 8.
