Polarization of connecters is achieved by a slotted feature on the header housing and a matching key on the mating wire-to-board receptacle housing. 4.6. A V-shaped recess in the connector housing provides a means of circuit identification. Typically this recess is used to locate the number one circuit, but another method may be used if desired (See Figure 1). 4.7. AMPMODU System 50 headers mate to receptacles as shown in Figure 5.

Fig. 5. Mating Connectors 4.8. Seated connector requirements are as follows: A. Solder tines may be clinched to the pe board in order to hold the connector assembly in place during handling and soldering, and to | ensure the integrity of the solder joints. The pe board and the connector assembly shall both be supported during the clinching operation. NOTE: The methods used to provide support and to clinch the tines is left to the customer's discretion, but the chosen method shall not apply pressure against the tines in a direction perpendicular to the board. Failure to comply may result in contacts being dislodged from their proper position in the housing. B. Seated, clinched connectors shall be completely flush to the pe board and shall appear as illustrated in Figure 6. AVR | 4M? Incorporated 114-25031 Harrisburg, Pa. 17105 AMP 1251-15CAUTION: Connectors are not to be used as the sole mechanical support between pc boards. The use of commercially available standoffs or card guides is recommended to ensure the mechanical integrity of the system.

Seated Connector Requirements 1414-25031 AMP INCORPORATED Harrisburg, Pa. 17105 aaa ume acCleaning and soldering shall be according to the following guidelines: A, Solder tines shall be fluxed prior to soldering using a non-activated to mildly activated rosin. Proper flux selection depends on the type of printed circuit board and any components already mounted. Flux must also be compatible with the customer's flow solder line and with manufacturing and safety requirements. Removal of fluxes, residues, and activators is mandatory. Cleaning procedures are chosen by the customer and depend on the type of flux used on his solder line. Extra consideration must be given to wave soldering parameters and pc board design to minimize solder bridging between adjacent leads due to the .050 centerline spacing on the connectors. When a trace must be run on the solder side of the board between adjacent pads as shown in Figure 2, mask must be applied over the trace. Recommended masks are: (1) Photo-imageable liquid mask. (2) Dry film solder mask. Orient the boards so that the length of the connector is perpendicular to the solder wave. Solderability of the board is also critical in the successful soldering of the connector. NOTE: The wave soldering process will vary among customers and equipment. It is recommended that each customer perform experi- mental runs to determine an optimum process providing maximum yields, Typical parameters are: Conveyor speed......... 6 feet per minute. Pre-heat temperature... 220F (Top Surface Of Board) Solder..ccscscacecesess 63/37 (495F Pot Temperature) D. AMP Corporate Bulletin No. 52 is available upon request and can be used as a guide in soldering. This bulletin gives various flux types and characteristics along with commercial designation and flux removal procedures. A checklist is attached to the bulletin to aid in obtaining information pertaining to soldering problems. 4.10. The following workmanship standards shall apply to the completed pe board assembly: A. The solder tines and hold-down features shall protrude through the pe board and be correctly soldered. B. The plastic connector housing aud pe board shall not sustain damage during the clinching or soldering processes to the extent that performance is affected. C. The assembly shall conform to all the requirements of the appropriate product drawing. " 114-2503] Arie | AMP inconporaten Harrisburg, Pa. 17105Cee ee | 5. TOOLING TYPES 5.1.
