INTRODUCTION NOTE Recommendations in this document are intended only for Tyco Electronics MICTOR SB product lines. i This specification covers requirements for application of MICTOR SB (Single Beam) Vertical Board-to-Board Plug and Receptacle Connectors for Surface Mount Technology (SMT) Printed Circuit (PC) Board Applications. The connectors have in-row contact centerline spacing of 0.50 mm [.0197 in.] and 0.80 mm [.0315 in.]. Depending on the contact centerline, the connectors are designed to accommodate 38 through 300 contact positions. Connectors are designed for manual or robotic placement on pc boards of various thicknesses. Plug connectors are available in various stack heights. The stack heights describe the board-to-board distance when assembled with a standard vertical receptacle. Plugs and receptacles have polarized mating faces, and are polarized for alignment to the pc boards by means of alignment pegs on the housing bottoms. Date codes are marked on the sides of the housings. Figure 1 provides connector features and terms used throughout this specification. Use these terms when corresponding with Tyco Electronics Personnel to facilitate assistance.

Product Materials MICTOR SB SMT Connector Housings are constructed of a high temperature thermoplastic - Liquid Crystal Polymer, UL94V-0. The plug and receptacle signal contacts, and the ground buses are made of phosphor bronze. The mating interface of the signal contacts and ground buses are underplated with nickel and finished with gold plating or with gold flash. The solder leads and tines have gold or gold flash plating. 3.2. Storage Connectors are packaged and shipped in protective anti-static trays or pocket tape which can be used for automated placement of the connector to the pc board. Connectors should remain in the containers until ready for use to prevent physical damage to the housings and contacts. The connectors should be used on a first in, first out basis to avoid storage contamination that could adversely affect signal transmissions and solderability of the contact tines. 3.3. Polarization Both the vertical plug and receptacle connectors are prevented from reverse mating by an orientation feature located at the ends of the connector that interfaces with the orientation holes in the pc board. See Figure 1. 3.4. Circuit Identification MICTOR SB SMT Vertical Plugs and Receptacles are not marked with a No. 1 pin identifier. Refer to Figure 1 and the following notes for recommendations regarding circuit identification. NOTE There is no industry standard for the callout of the pin number numbering sequence for MICTOR SB SMT Connectors. It is up to the customers' discretion. However, the most common method is to start with pin number 1 (reference i recommended pc board pad identification in Figure 5, with alignment pegs aligning connector to the pc board pattern) and proceed to number 2 pin directly on the opposite side of the connector. Pin number 3 would then be adjacent pin number 1, with pin number 4 adjacent to pin number 2, and so on. NOTE The ground bus contacts of all MICTOR SB true SMT style connectors are internally commoned within each module, with each module having four surface mount style leads. MICTOR SB SMT Connectors come in three contact i 2 of 16 centerline versions, with each version having a different number of contacts per module as listed in the table in Figure 2.

Spacing A. Connector Alignment CAUTION To prevent solder joint damage, care should be used when mating connectors to ensure they have the freedom to self align themselves to each other without binding in any manner that may result in axial forces being transferred through ! CAUTION the solder joints. Tyco Electronics does NOT recommend the use of more than one mating connector between two pc boards. The use of multiple connectors on one board mating to multiple connectors on another board may be plagued with issues ! regarding connector-to-connector positional tolerances that may result in unfavorable solder joint stress. B. Board-to-Board Spacing Board-to-board stacking heights for the MICTOR SB SMT Vertical Connectors are provided in the table in Figure 3.

PC Boards for MICTOR SB SMT Connectors A. Tolerance At the time of connector placement, the coplanarity of the pad pattern must be held to 0.05 mm [.002 in.] maximum. We recommend 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.]. Maximum allowable bow of the pc board shall be 0.10 mm [.004 in.] over the length of the connector. 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 ! Rev A would not provide long term performance for the connector.

Material and Thickness Since MICTOR SB SMT Vertical Connectors for Surface Mount Technology are true SMT parts, the pc board thickness is irrelevant. However, special caution should be taken to ensure the pc boards are at least thick enough to ensure board stability, (flatness, etc.) throughout the reflow process and be rigid enough to support mate and unmate cycling. C. PC Board Layouts The recommended pc board patterns depend on the appropriate connector centerline, (0.50 mm [.0197 in.], 0.635 mm [.025 in.], or 0.80 mm [.0315 in.]), and type, (receptacle or plug) are provided in Figure 4.

Placing holes at the ends of the connectors may cause the ends of ! 6 of 16 the connectors to act as fulcrum points to pry apart the opposite end or mid-portion of the connector as the hold-down or spacer hardware is tightened. Tyco Electronics Corporation Rev A MICTOR SB SMT Vertical Connectors CAUTION 114-13116 Tyco Electronics does NOT recommend the use of more than one mating connector between two pc boards; if such a configuration is necessary to meet design requirements, consult the Product Information number located at the bottom of page 1. ! 3.7. Mechanical Supports To ensure the pc board does not bow during placement and a misapplication occurs, the pc board should be supported along the full length of the connector. 3.8. Processing NOTE PC Boards must meet the solderability requirements of IEC 60512-12-1 (512-6: 1984 Test 12a). i A. Stencil The recommended 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, the thinner stencil will need a larger aperture to maintain the given volume of solder paste. The formulas for calculating the apertures for the MICTOR SB SMT Connector pads are as follows. Refer to Figure 6.

Exposed traces could cause bridging and create a short, or wick solder away from the solder tines, producing a weak solder joint. ! CAUTION 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. ! NOTE The recommended aperture width is 0.43 mm [.017 in.] for the vertical connector circuit contact pads. It may be wider; however, care must be given to ensure against solder bridging during processing. i The recommended solder stencil layouts for MICTOR SMT Connectors are shown in Figure 5.

Solder Mask Solder mask is recommended between all pads, ground bus vias, and angular rings. 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 surrounding the bus lead solder deposit. Liquid photo imageable or dry film solder masks, in step with modern processing techniques are recommended. C. Recommended Solder Paste Characteristics 1. Alloy type shall be either 63 Sn/37Pb or 60 Sn/40Pb. 2. Flux shall be RMA type. 3. Solids by weight shall be 85% minimum. 4. Mesh designation -200 to +325 (74 to 44 square micron openings, respectively). 5. Minimum viscosity of screen print shall be 5 x 105 cp (centipoise). 6. Minimum viscosity of stencil print shall be 7.5 x 105 cp (centipoise). D. Solder Volume Solder volume for each circuit pad and bus tine opening is calculated by multiplying the pad length by the pad width by the stencil thickness (Volume=LxWxT). The recommended volume for these connectors is determined with a mean stencil thickness of 0.15 mm [.006 in.]. Refer to the table in Figure 6.

NOTE More technical information may be available from the manufacturer of the stencil. i E. Connector Placement Vertical Connectors The vertical plugs and receptacles are positioned on the pc board by matching the orientation feature on the bottom of the housing to the unplated holes. NOTE The pc board should be firmly supported in the area directly beneath the connector during placement to prevent the pc board from flexing. Refer to Paragraph 5.1. i NOTE Connectors are available in shipping trays or on tape reels and should be placed directly from the package to the pc board. Tyco Electronics does NOT recommend emptying them from the package into piles or in bowl feeders prior to i placement. CAUTION Connectors should be handled only by the ends. DO NOT touch the solder tines, as moisture from the hands will contaminate the soldering process and lead position or coplanarity may be compromised. ! NOTE Optimally, the connector solder tines should be centered on the pc board pads. However, slight misalignment is permissible. See Figure 7. i Typical for MICTOR SB SMT Vertical Connectors Tine Centered on PC Board Pad is Preferable Solder Tine Tine Overhang up to 50% Max is Acceptable Per ANSI J-STD 001A (Class 2) PC Board Pad PC Board Figure 7 F.

Connector Capacity Connectors will withstand the maximum temperature time limits specified in Figure 8. 3. 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. G. Cleaning After soldering, removal of fluxes, residues, and activators is necessary. Consult with the supplier of the solder paste and flux for recommended cleaning solvents. The following is a listing of common cleaning solvents that will not affect the connectors. The connectors will be unaffected by any of these solvents for 5 minutes at 105_C [221_F]. See Figure 9. Cleaners must be free of dissolved 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 soak-tank or an automatic in-line machine CAUTION 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 even with no clean" paste.

Thermal flexing of the pc board will result in either the connector body following the pc board contour or lifting off the board. ! Rev A Tyco Electronics Corporation 13 of 16 MICTOR SB SMT Vertical Connectors DANGER 114-13116 Consideration must be given to toxicity and other safety requirements recommended by the solvent manufacturer. 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. NOTE If you have a particular solvent that is not listed, contact the Product Information number at the bottom of page 1. i H. Drying Air drying of cleaned connectors is recommended. Temperature for the connectors should not exceed -55 to 105_C [-67 to 221_F]. Degradation of the housings could result from extreme temperatures. 3.9. Mating and Unmating CAUTION Uneven or off-angle forces during mating and unmating of MICTOR SB SMT Connectors may cause overstress and damage to the contacts, housings or solder joints. Severe side-to-side rocking motions should be prohibited. ! Unmating MICTOR SB SMT Connectors by lifting one end of the connector (peeling) is permitted. However, this should only be done to initiate separation of the mated contacts at one end of the connector. The separation angle should be kept as low as possible as the contacts continue to unmate, thereby spreading out the unmating forces over the length of the connectors. The connectors should not be "peeled" beyond a 20 angle. Miniaturization is a design feature of these connectors and the systems in which they are used. Component density, connector location, and pc board size may make it difficult to remove the connector. Two methods are recommended to facilitate removal. If unmating board-to-board connectors, the preferred method is to have one of the pc boards securely fastened and adequately supported to withstand the pulling force applied to the other pc board. The second method is to construct a tool for your system design that will produce a straight-away separation of the connectors. See Figure 10. CAUTION Application of unmating forces to the pc boards should be done within close proximity of the connector (preferably within 25.4 mm [1.000 in.] on 1.57 mm [.062 in.] thick pc boards). Stress on the solder joints will increase as the force ! is applied further from the connector. Preferred _Max. 20 Permissible _Max. 4 Lift Evenly Figure 10 3.10. Repair/Removal Connectors may be removed from the pc board by standard SMT de-soldering methods. Damaged connectors must be replaced. 4.

TOOLING 5.1. PC Board Support A pc board support must be used to prevent bowing of the pc board during the placement of a connector on the board. 5.2. Robotic Equipment MICTOR SB SMT Connectors are pick-and-place compatible. They are normally packaged in trays, but vertical receptacles and plugs are also available in pocket tape (with or without vacuum pick-up dots). MICTOR SB SMT Vertical Receptacles and Plugs may be applied using robotic grippers or vacuum heads. Robotic placement equipment should be capable of accurately locating connectors for pc board insertion using the connector datum surfaces detailed on the customer drawing. Several robotic companies have experience with placing MICTOR SB SMT Connectors and can be called upon for assistance. They are: Rev A Universal Instruments Corporation P.O.
