Ultraviolet Light Prolonged exposure to ultraviolet light may deteriorate the chemical composition used in connectors. B. Shelf Life The connectors should remain in the shipping containers until ready for use to prevent damage. They should be used on a first in, first out basis to avoid storage contamination that could adversely affect signal transmissions. C. Chemical Exposure Do not store connectors near any chemicals listed below, as they may cause stress corrosion cracking in the components. Do not store modular jacks near any chemicals listed below, as they may cause stress corrosion cracking in the components. Alkalies Ammonia Cittrates Phosphates Citrates Sulfur Compounds Amines Garbonates Nitrites Sulfur Nitrites Tartrates 3.2. Mating To ensure full mating of the connectors, the length between the mated connectors must be considered when determining the method of mounting and the panel thickness when the connector is fo be mounted to it.

Connector Shell Sizes There are five industry standard shell sizes available for these connectors. A composite of the five sizes with the overall dimension for each is provided in Figure 3. 52.324 [2.064] 16.33 [.643] Receptacle Shell Sizes + Figure 3 jeg 100 yd 3.4. Printed Circuit Board A. Thickness The connectors are designed for pc boards up to 3.18 [.125] thick. Those with post lengths of 3.18 [.125] are recommended for pc boards up to 2.36 [.093] thick. Those with post lengths of 4.32 [170] are recommended for pc boards up to 3.18 [.125] thick. B. Layout Patterns The connectors are placed on the pc board manually. Gare should be taken to prevent deformation of the contact solder tines prior to insertion into the pc board. It is important to note that the contact solder tines require precise hole dimensions. The pc board holes must be drilled and platedthrough to the dimensions provided in Figure 4.

Polarization and Keying Figure 6 The keystone configuration of the mating face prohibits the accidental inversion of mating connectors. To prevent mismating connectors of the same size, keying plugs may be placed in the receptacle connector. The matching pin in the mating plug connector must be omitted. See Figure 7.

Shielding The connectors feature tinplated steel shells that provide electromagnetic compatibility (EMC). When mated with another metal shell connector, both shielding and grounding continuity are achieved. Use of metallic hardware provides additional reinforcement of electrical continuity. 3.8. Mounting Hardware There are connectors with standard mounting hcles which can be attached to the pc board with long female screwlock kits or commercially available hardware. Also, there are connectors with threaded retention inserts to be attached with short female screwlocks, and there are connectors with fixed female screwlocks. The recommended application for each type of hardware is shown in Figure 8. A. Connectors with Screwlocks Mounting hardware used to secure cable connectors to pe board connectors that have screwlocks must not exceed the torque value of 0.23 Nem [2 inIb]. B.

Soldering 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.

Soldering Guidelines AMPLIMITE HD20 Straight Contact Tine Connectors can be soldered using wave or equivalent soldering techniques. The temperatures and exposure time shall be within the ranges specified in Figure 10. We recommend using SN60O or SN62 solder for these connectors. Neha AMP Corporate Bulletin 401-52 provides some guidelines for establishing soldering practices. SOLDERING TEMPERATURE TIME PROCESS CELSIUS FAHRENHEIT (At Max Temp) WAVE SOLDERING 26088 50088 5 Seconds 3 Wave Temperature Figure 10 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. The following is a listing of common cleaning solvents that will not affect the connectors for the time and temperature specified. See Figure 11. Cleaners must be free of cissolved flux and other contaminants. We recommend cleaning with the pc board on its edge. If using an aqueous cleaner, we recommend standard equipment such as a soaktank or an automatic in-line machine. Ey Consideration must be given to toxicity and other safely requirements recommended by the solvent manufacturer. Refer to the manufacturers Material Safety Data Sheet (MSDS) for characteristics and handling of cleaners. Trichioroethylene and Methylene Chioride can be used with no harmful affect to the connectors; however AMP does not recommend them because of the harmful occupational and environmental effects. Both are carcinogenic (cancer-causing) and Trichloroethylene is harmful to the earths ozone layer.
