INTRODUCTION This specification covers the requirements for application of SFP and SFP+ surface mount PT connectors and cage assemblies to interconnect SFP and SFP+ fiber optic or copper transceiver modules to printed circuit (pc) boards. The connectors are available in 20, 30, 40, and 70 positions with contact spacing on 0.8 mm centerlines; however, ONLY the 20--position connector is designed to be used with these cage assemblies. The cage assemblies are available in single port or ganged 12, 14, or 16 configurations (two, four, or six adjoined ports), and with or without a light pipe. The light pipe is used to transmit light from an LED on the pc board to a panel (information for cage assemblies with light pipe is not included in this document). Each cage assembly is designed to be inserted into a bezel after being seated onto the pc board. The connector is supplied in tape--and--reel form for manual or high--speed automatic machine placement (typically vacuum pick and place). The cage assemblies are supplied in plastic tray packaging for manual placement.

Solder Paste Characteristics 1. Alloy type for tin--lead solder shall be 63 Sn/37 Pb, 60 Sn/40 Pb, or 62 Sn/36 Pb/2 Ag. Alloy type for lead--free solder shall be compatible with pure tin or gold; for example, SAC305 (96.5 Sn/3 Ag/0.5 Cu) or SAC405 (95.5 Sn/4 Ag/0.5 Cu). 2. Flux incorporated in the paste shall be rosin, mildly active (RMA) type. 3. Paste will be at least 80% solids by volume. 4. Mesh designation --200 to +325 (74 to 44 square micron openings, respectively). 5. Minimum viscosity of screen print shall be 510% cp (centipoise). 6. Minimum viscosity of stencil print shall be 7.510% cp (centipoise). 3.8. Solder Volume Minimum solder volume (V) (before curing) for each circuit pad is calculated by multiplying the pad length (L) by the pad width (W) by the stencil thickness (T): 2.0(L)0.5(W)0.15(T) = 0.15 mm3 (V) Solder volume for each connector must be 0.15 mm3 per contact solder tine. NOTE Solder volume may vary depending on solder paste composition. i 3.9. Solder Paste Thickness Solder paste thickness for the connector contact solder tines must be at least 0.15 mm. Rev C Tyco Electronics Corporation 7 of 17 SFP and SFP+ Surface Mount PT Connectors Cage Assemblies 114-- 13120 3.10. Stencil The stencil aperture is determined by the circuit pad size and stencil thickness. It may be any shape as long as it prevents solder bridging from one pad to another. Generally, a thinner stencil will need a larger aperture to maintain the given volume of solder paste. The stencil should be 0.15 mm thick. The stencil layout must be designed using the dimensions provided on the customer drawing for the specific connector. Sample stencil layout is provided in Figure 4. Sample Recommended Connector Stencil Layout Note: For Specific Circuit Pad Locations, Refer to the Customer Drawing for the Specific Connector Figure 4 3.11. Solder Mask When soldering, solder mask is recommended between all circuit pads to minimize solder bridging between pads. The mask must not exceed the height of the pad. If a trace is run between adjacent pads on the pc board, a solder mask must be applied over the trace to prevent bridging and wicking of solder away from the connector contact solder tines. Mask most suitable is Liquid Photo Imageable. CAUTION ! 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. 3.12. Connector Placement CAUTION ! NOTE Connectors should be handled only by the housing to avoid deformation, contamination, or damage to the contact solder tines. The connector must be soldered to the pc board BEFORE seating the cage assembly. i A. Registration The connector contact solder tines must be aligned with matching circuit pads and alignment posts aligned with matching holes before placing the connector onto the pc board. B. Position Optimally, the connector contact solder tines should be centered on the pc board circuit pads. However, slight misalignment is permissible as shown in Figure 5. 8 of 17 Tyco Electronics Corporation Rev C SFP and SFP+ Surface Mount PT Connectors Cage Assemblies 114-- 13120 Contact Solder Tine Overhang Up to 50% is Permissible PC Board Contact Solder Tine Centered on PC Board Circuit Pad Preferred Figure 5 C. Seating Because the connector alignment posts are for clearance and fit only, the force required to seat the connector is minimal. Apply only that force necessary to seat the contact solder tines into the top surface of the solder paste. The alignment posts must be inserted into the pc board holes and the standoffs must be seated on the board. See Figure 6. Connector Standoff (2 Places) Seated on Board Contact Solder Tine Seated on Circuit Pad PC Board Alignment Post (2 Places) Inserted into Hole in PC Board Figure 6 3.13. Soldering A. Process The connector must be soldered using non--focused infrared (IR) reflow or equivalent soldering technique. When mounting to both sides of the pc board, the surface tension of the solder, when it is in the liquid state, will hold the connector on the board. Reflow temperature and time may vary depending on the size of the pc board and placement of other components. The reflow temperature and approximate time to which the connector can be subjected is specified in Figure 7. CAUTION ! Rev C Excessive temperatures may cause connector housing degradation. It is recommended that component temperatures not exceed 230_C [446_F] when using tin--lead solder and 260_C [500_F] when using lead--free solder.

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. It is recommended cleaning the pc board on its edge. If using aqueous cleaner, standard equipment such as a soak--tank or an automatic in--line machine should be used. Common cleaning solvents that will not affect the connector for the time and temperature specified are listed in Figure 8. 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).

Cage Assembly Placement NOTE The connector must be soldered to the pc board BEFORE seating the cage assembly. i A. Registration The compliant pin contacts and EMI suppression pins must be aligned with matching holes in the pc board, then inserted into the pc board simultaneously to prevent twisting or bending of these parts. B. Seating Using proper seating force and seating height is essential to interconnection performance. The force used to seat the cage assembly must be applied evenly to prevent deformation or other damage to the compliant pin contacts. The force required to seat the cage assembly onto the pc board can be calculated by: Amount of Compliant Pin Contacts 44.5 N [10 lbs] (Force per Compliant Pin Contact) = Seating Force CAUTION ! Rev C Over--driving of the cage assembly will deform parts critical to the quality of the connection. Maximum force occurs prior to the cage assembly bottoming on the pc board. Tyco Electronics Corporation 13 of 17 114-- 13120 SFP and SFP+ Surface Mount PT Connectors Cage Assemblies When using tooling to seat a ganged cage assembly, the shut height of the application tool must be specifically set for proper seating of the cage assembly. The shut height can be calculated by: Seating Height (Cage Assembly Seated) + Height of Seating Tool + Combined Thicknesses of PC Board and PC Board Support Fixture = Shut Height (Ram Down) NOTE i The shut height may need to be adjusted to maintain the 0.10 mm maximum gap between the standoffs of the cage assembly and the pc board. The cage assembly must be seated on the pc board not exceeding the dimensions shown in Figure 11.
