1、 EIA SPECIFICATION Specification for Mini Multilane 10 Gb/s 4X Common Element Connectors EIA-974 (Was SFF-8086, Rev 2.3, dated January 5, 2012) March 2015 Electronic Components Industry Association EIA-974 ANSI/EIA-974-2015 Approved: March 18, 2015 NOTICE EIA Engineering Specifications and Publicati
2、ons are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need.
3、 Existence of such Specifications and Publications shall not in any respect preclude any member or nonmember of ECIA from manufacturing or selling products not conforming to such Specifications and Publications, nor shall the existence of such Specifications and Publications preclude their voluntary
4、 use by those other than ECIA members, whether the standard is to be used either domestically or internationally. Specifications and Publications are adopted by ECIA in accordance with the American National Standards Institute (ANSI) patent policy. By such action, ECIA does not assume any liability
5、to any patent owner, nor does it assume any obligation whatever to parties adopting the Specification or Publication. This EIA specification is considered to have International Standardization implications, but the International Electrotechnical Commission activity has not progressed to the point wh
6、ere a valid comparison between the EIA standard and the IEC document can be made. This Specification does not purport to address all safety problems associated with its use or all applicable regulatory requirements. It is the responsibility of the user of this Specification to establish appropriate
7、safety and health practices and to determine the applicability of regulatory limitations before its use. (From Standards Proposal No. 5289, formulated under the cognizance of the CE-2.0 Committee on EIA National Connector and Socket Standards, and previously published by the SFF Committee as SFF-808
8、6.) Published by Electronic Components Industry Association 2015 EIA Standards the bits, bytes, fields and code values are set aside for future standardization. The default value shall be zero. The originator is required to define a Reserved field or bit as zero, but the receiver should not check Re
9、served fields or bits for zero. 3.17 Right angle A connector design for use with printed circuit board assembly technology where the mating direction is parallel to the plane of the printed circuit board. 3.18 SFP Small Formfactor Pluggable 3.19 Single row A connector design for use with surface mou
10、nt printed circuit board assembly technology where the termination side points are arranged in one line. 3.20 Single sided termination A cable termination assembly style and a connector design style where only one side of the connector is accessible when attaching wires. This style frequently has ID
11、C termination points that point in the same direction. EIA-974 Page 5 3.21 SMT Surface Mount Technology 3.22 Straddle mount A connector design style and a printed circuit board design style that uses surface mount termination points on both sides of the board. The connector is frequently centered be
12、tween the top and bottom surfaces of the board. 3.23 Straight A connector design for use with printed circuit board assembly technology where the mating direction is perpendicular to the plane of the printed circuit board. 3.24 Surface mount A connector design and a printed circuit board design styl
13、e where the connector termination points do not penetrate the printed circuit board and are subsequently soldered to the printed circuit board. 3.25 Termination side The side of the connector opposite the mating side that is used for permanently attaching conductors to the connector. Due to pin numb
14、ering differences between mating side genders the termination side shall always be specified in conjunction with a mating side of a specific gender. Other terms commonly used in the industry are: back end, non-mating side, footprint, pc board side, and post side. 3.26 Through hole A connector design
15、 and a printed circuit board design style where the connector termination points penetrates the printed circuit board and are subsequently soldered to the printed circuit board. Figure 3.1 - Mating side gender definition EIA-974 Page 6 3.27 Conventions The ISO convention of numbering is used i.e., t
16、he thousands and higher multiples are separated by a space and a period is used as the decimal point. This is equivalent to the English/American convention of a comma and a period.

17、ion The Mini Multilane Series relies on a receiving body and paddle card, which are the primary elements to construct connectors. The primary elements provide a flexible means to implement solutions for diverse applications e.g., direct board-to-board implementations can incorporate the plug into th
18、e side of one board and mate directly to a receiving body on the other. EIA-974 Page 7 4.1 General view Figure 4.1 is an example, which illustrates two styles of receiving bodies and how they become receptacles to receive the plug when encapsulated by the shell that is designed for an unshielded con
19、nector application. Figure 4.1 - General view of fixed (receptacle) configuration 4.1.1 EIA-975 defines the free (plug) cable connector that incorporates the paddle card and the shell, which is used to encapsulate the receiving body to form a complete receptacle for use in unshielded applications. 4
20、.1.2 EIA-976 defines the free (plug) cable connector that incorporates the paddle card and the shell, which is used to encapsulate the receiving body to form a complete receptacle for use in shielded applications. EIA-974 Page 8 4.1.3 The shell provides guidance and retention for the free (plug) cab
21、le connector, and absorbs the stress imposed by insertion and removal of the free (plug) cable connector. This protects the signal quality of the solder joints to the body. 5 Connector dimensions The dimensioning conventions are described in ANSI-Y14.5M, Dimensioning and Tolerancing. All dimensions
22、are in millimeters. Dimension related requirements for the connector system addressed in this document are specified in the tables and figures in this clause. 5.1 Free (plug) paddle card Figure 5.1 Free (plug) paddle card EIA-974 Page 9 Table 5.1 Free (plug) paddle card dimensions Designator Descrip
