Dimensions are in millimeters [and inches]. Unless otherwise specified, dimensions have a tolerance of +0.13 [+.005] and angles have a tolerance of +2_. Figures and illustrations are for identification only and are not drawn to scale. 1. INTRODUCTION This specification covers the requirements for application of MULTI--BEAM XL connectors onto printed circuit (pc) boards for use in power supplies. These connectors consist of vertical receptacle assemblies, right--angle receptacle assemblies, vertical header assemblies, and right--angle header assemblies. The connectors are available with either precision formed press--fit (compliant pin) contacts or solder type contacts. Each connector consists of a housing with power modules containing one power contact and signal modules containing 4 rows of signal contacts, either pin or socket. The signal pin contacts (only in header assemblies) are available in two contact mating lengths: standard and mate--last break--first (MLBF) (post mate), and the power contacts (only in receptacles) are available in two contact mating lengths: standard and mate--first break--last (MFBL) (pre--mate) for sequencing applications. NOTE i The amount of power and signal contacts in a connector is customer specified. Any connector configuration can be designed to meet customer requirements--provided it is within the limitations stated in this document. 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.

Figure 1 (End) The maximum overall length allowed for the connector is 203 [8]. Combinations of up to 36 power contacts and 148 signal contacts can be used--provided the maximum allowable length is not exceeded. Power modules are available with contact centerline spacing of 5.08 [.200], 6.35 [.250], 7.62 [.300], 9.53 [.375], and 10.8 [.425], and signal modules have a contact centerline spacing of 2.54 [.100]. End modules and center modules are available with features that provide blind mating, misalignment, and polarization. End modules contain a guide post, guide hole, or latch receiver with key slot and a hold--down clip, and/or mounting hole, and center modules contain a hold--down clip or mounting hole. End modules without guides are also available. Guides (posts on receptacles and holes in headers) have rounded edges for ease of mating and are offset to prevent improper mating of connectors. The latch receiver with key slot ensures proper orientation of connectors when mating and that the connectors do not accidentally back--out. The hold--down clips help to align the connector to the pc board for installation then secure the connector for soldering. The mounting holes (which accept commercially--available standard screws) are also used to secure the connector to the pc board. The mounting holes are available with 3.10 [.122] or 3.81 [.150] diameter. The connectors feature standoffs (one located at each contact) to facilitate pc board cleaning after soldering. Convection windows and cored lances located on the housing provide air flow for power modules. The connectors are supplied in tray form for manual placement. These connectors mate with MULTI--BEAM XL cable receptacle assemblies (covered in Application Specification 114--13112) and MULTI--BEAM XL cable plug assemblies (covered in 114--13164). 2.

Soldering Observe guidelines and procedures when soldering contacts. Contact solder tails must be soldered, cleaned, and dried according to the following: A. Flux Selection Contact solder tails must be fluxed prior to soldering with a mildly active, rosin base flux. Selection of the flux will depend on the type of pc board and other components mounted on the board. Additionally, the flux must be compatible with the wave solder line, manufacturing, health, and safety requirements. Flux that is compatible with these connectors are provided in Figure 9. Rev H Tyco Electronics Corporation 7 of 15 MULTI- BEAM XL Connectors 114- 13038 COMMERCIAL DESIGNATION KESTER 186 ALPHA 611 FLUX TYPE RMA ACTIVITY Mild RESIDUE Noncorrosive Figure 9 B. Process The connectors can be soldered using wave soldering or equivalent soldering techniques. It is recommended using tin or tin--lead solder for these connectors. Refer to Manual 402--40 for soldering guidelines. The temperatures and exposure time shall be as specified in Figure 10. SOLDERING PROCESS Wave WAVE TEMPERATURE 265_C [509_F] Figure 10 TIME (At Maximum Temperature) 10 Seconds C. Cleaning After soldering, removal of fluxes, residues, and activators is necessary. Consult with the supplier of the solder and flux for recommended cleaning solvents. Cleaners must be free of dissolved flux and other contaminants. Common cleaning solvents that will not the affect connectors for the time and temperature specified are listed in Figure 11. DANGER Consideration must be given to toxicity and other safety requirements recommended by the solvent manufacturer. Refer to the manufacturer's Material Safety Data Sheet (MSDS) for characteristics and handling of cleaners. Trichloroethylene and Methylene Chloride is not recommended because of harmful occupational and environmental effects. Both are carcinogenic (cancer--causing). Even when using "no clean" solder paste, it is imperative that the contact interface be kept clean of flux and residue, since it acts as an insulator. Flux may migrate under certain conditions with elevated temperatures and therefore, cleaning is necessary. CAUTION !
