REQUIREMENTS 3.1. Storage A. Ultraviolet Light Prolonged exposure to ultraviolet light may deteriorate the chemical composition used in the housing material. B. Reel Storage When using reeled contacts, store coil wound reels horizontally and traverse wound reels vertically. C. Shelf Life Each connector is packaged and shipped in an individual antistatic tube container or tape and reel (SMT only). To prevent damage to the housings and contact solder tines, the connectors should remain in the container until ready for installation. Also, to prevent possible storage contamination and ensure maximum solderability, the connectors should be used on a first in, first out basis. D. Chemical Exposure Do not store contacts near any of the following chemicals as they may cause stress corrosion. Alkalies Amines NOTE i Ammonia Carbonates Citrates Nitrites Phosphates Citrates Sulfides Nitrites Sulfur Compounds Tartrates Where the above environmental conditions exist, phosphor--bronze contacts are recommended instead of brass if available. 3.2. Materials AMPMODU MTE Receptacle and Header Connectors are constructed of black glass--filled thermoplastic, UL94V--0. The receptacle and header contacts are made of phosphor bronze with the mating interface of the contacts underplated with nickel and finished with gold or tin--lead plating. The MTE header's solder tines have a matte tin--lead plating on gold plated posts, and bright tin--lead plating on tin--lead plated posts. 3.3. Circuit Identification AMPMODU MTE Connectors are marked with a V--shaped circuit number one identifier. See Figure 1. 3.4. Cable and Wire Selection and Preparation Contact types, sizes, and tooling choices will effect the range of wire size available as shown in Figure 2. These values apply whether using discrete wire, jacketed cable, slit ribbon cable, or slit round conductor flat cable. NOTE i 4 of 20 Discrete wires require no preparation for termination, but insulation displacement contacts must be used. Do not cut the individual conductor insulation when stripping the outer cable jacket or braided shield.

The following special considerations apply to terminated contacts. A. Terminating Head In all tools except the terminating head used for the pistol--grip hand tool and pneumatic power assembly, final contact insertion is done automatically by the tooling. Using the terminating head requires manual removal of the carrier strip and manual contact insertion. NOTE i Tyco Electronics recommends that contacts be inserted after carrier strip removal. However, when using 8--position or smaller housings, contacts may be mass inserted before removal of the carrier strip. See Figure 3.

Connector Placement for Through- Hole Configurations CAUTION ! Connectors should be handled only by the housing to avoid deformation, contamination, or damage to the contact tines. When placing through hole connectors on the pc board, make sure the contact solder tines are aligned and started into the matching holes before seating the housing on the pc board. 3.9. Soldering Through- Hole Connectors A. Flux Selection Contact solder tines 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. Call the Product Information phone number at the bottom of page 1 for consideration of other types of flux. Some fluxes that are compatible with these connectors are provided in Figure 9. FLUX TYPE ACTIVITY RESIDUE Type RMA (Mildly Activated) Mild Noncorrosive COMMERCIAL DESIGNATION KESTER ALPHA 186 611 Figure 9 B. Cleaning After soldering, removal of fluxes, residues, and activators is necessary. Consult with the supplier of the solder and flux for recommended cleaning solvents. The following is a listing of common cleaning solvents that will not affect the connectors for the time and temperature specified. See Figure 10. DANGER NOTE i Rev D 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 can be used with no harmful affect to the connectors; however Tyco Electronics does not recommend them because of the harmful occupational and environmental effects. Both are carcinogenic (cancer--causing) and Trichloroethylene is harmful to the earth's ozone layer. If you have a particular solvent that is not listed, contact the Tooling Assistance Center or Product Information number at the bottom of page 1.

Stencil Stencil aperture will be determined by the thickness of the stencil being used. Generally, the thinner stencils will have a larger aperture to maintain a given volume of solder paste. Solder deposition should be within the pad area of the contact solder tines. A typical aperture opening is provided in Figure 13. CAUTION ! CAUTION ! NOTE i Rev D All traces must be covered by solder mask in the solder deposit area. Exposed traces could cause bridging and create a short, or wick solder away from the solder tines, producing a weak solder joint. If a hold--down aperture is required other than that specified, the design must ensure that the connector housing will not sit on the solder deposit. The recommended aperture width is 0.064 mm [.025 in.] , It may be wider, however, care must be given to ensure against solder bridging.

Solder Screen Generally, we do not recommend screen application of solder paste because of the limited volume of paste that can be deposited. If a screen application is required, we recommend removal of all screen from the solder tine and hold--down pad areas. Consult your supplier for compatibility of screen and paste, and for application techniques. E. Solder Mask Solder mask is recommended between all pads. If a trace is run between adjacent pads on the solder side of the pc board, a solder mask must be applied over the trace to prevent bridging and wicking of solder away from the contact solder tines. Additionally, there should be solder mask covering any traces in the area of the hold--down solder deposit. Liquid photo imageable or dry film solder masks are recommended. 14 of 20 Tyco Electronics Corporation Rev D AMPMODU MTE Interconnection System 114- 25026 F. Connector Placement SMT header connectors can be placed on the pc board by hand or by pick and place equipment. If doing so by hand, grip the connector at the ends of the housing without touching the contact to prevent contamination and deformation of the solder tines. See Figure 14. At the time of connector placement, the coplanarity of the pad pattern must be held to 0.05 mm [.002 in.] maximum. Tyco Electronics recommends a solder mask to minimize solder bridging between pads. The mask must not exceed the height of the pad by more than 0.05 mm [.002 in.]. CAUTION ! Since the connector housings may rest on top of the solder mask, an excessively high mask will allow too much space between the solder tine and pad for a good solder joint. A solder joint under these conditions would be weak, and would not provide long term performance for the connector. Connector Housing Tine Centered on Pad is Preferable Solder Tine Tine Overhang May be Acceptable for Some Performance Classifications Per IPC-- S-- 815 PC Board Pad PC Board Figure 14 G. Solder 1. Fluxing Selection Refer to Paragraph 3.9.A for flux selections. 2. Techniques It is recommended that the connector be soldered using convection, vapor phase (VPR), double sided non--focused infrared (IR), or equivalent soldering technique provided the temperatures and exposure time are within the ranges specified in Figure 15. Higher temperatures can be withstood for short periods of time as indicated in Figure 15 for the IR reflow. Tyco Electronics recommends using a Corpane Batch Vapor Phase (Model VVP 10 BU) and Vitronics IR (Model SMD 718) equipment.

Reflow Parameters Due to the many variables involved with the reflow process (ie, component density, orientation, etc), we recommend that the user conduct trial runs under actual manufacturing conditions to ensure product and process compatibility. H. Cleaning Refer to Paragraph 3.9.B for cleaning information. I. Drying Air drying of cleaned connectors is recommended. Temperature for the connectors should not exceed --65_C to 105_C [--83_F to 221_F]. Degradation of the housings could result from extreme temperatures.
