Nominal dimensions, i.e. , dimensions without tolerances, may be used, but shall be followed either by the letters “RFE“ when used for general information or by “TP“ 0r;“BSC“ when used to specify true geometrical positions by means of linear or angular di
16、mensions. ANSI document ANSI Y14.5 Dimensioning and Tolerancing (latest ievision) will be used as the definitive reference on all outlines. Outline drawings may be submitted for balloting on either the derimalired-inch or the metric system. Conversions to the other system must be made to the other s

Each table and drawing shall have a note as follows: Note - 1/ Control 1 ing dimension: MILLIMETERS Note - 2/ Controlling dimension: INCH or Indexes (Indices) The outlines sha

These outlines w
34、ill be in two categories: (a) Registered Outlines which indicate that there is some use of the part in the electronics industry and (b) Standard Outlines which have acquired broad usage in the industry and are accepted as highly representative of the type of parts described. The committee will attem
35、pt to discourage proliferation of outlines and will serve to encourage cooperation between manufacturers and users to provide the best possible descriptions. Special effort will be made to encourage new technology and new techniques for packaging parts. HEHBERSHIP All individuals representing the el
36、ectronic industry are encouraged to participate. Broad representation is planned from parts users, parts manufacturers, governmental agencies, and general interest industry members. Members of the EIA Parts Division may participate by requesting committee membership for their representative. Compani
37、es not members of the parts division may request membership and pay a participation fee. All committee members are expected to participate actively by attendance at meetings and by the return of mail ballots. ORGAHIZATIOH Committee will be directed by a Chairman appointed by the Chairman of the Part
38、s Engineering Panel. The term of the Chairman is for one year which may be extended on a yearly basis, based on the formal recommendation of the committee membership and the approval of the Parts Engineering Panel Chairman. A Vice-chairman will be appointed to serve in the absence of the Chairman. S
39、ubcommittee or working groups may be appointed by the Chairman to work on specific product areas and/or to perform specific tasks. All subcommittees and task groups must report in writing at each committee meeting. The committee organization and activity is responsible to the Parts Engineering Panel
40、 and the EIA Parts Division. -16- EIA PDP-LOO 87 3234600 0554742 T84 EIA-PDP-100 HEETINGS Will be held on a regularly scheduled.basis several times per year in order to coordinate similar outlines, to expeditiously resolve negative ballots or to resolve conflicts. -17- - _ EIA PDP-LOO 7 3234600 0554

Numerical Format This character identifies the type of numbering system used for the following four numerical digits. Format identifiers are as follows: M - The four digit nupiber
47、is used as follows: The first two digits indicate the approximate length of the part in tenths of a millimeter. The third and fourth .digits indicate the approximate width of the part in tenths of a millimeter. Example: A part 3.2ain by 1.h has a numerical descriptor of 3216 C - The four digit numbe
48、r is used as follows: The first tm, digits indicate the approximate length of the part in millimeters. The third and fourth digits indicate the approximate width of the part in llimeteir. N - The four digits are not significant- The numbers are issued sequen- tially and indicate a position in a numb
49、er of designations whose features are otherwise similar. 6. Out1 ine Variations variations of outlines may be listed on a single sheet. Variations must not require changes in the pdnciple drawing but may only use one or two variations in the table of dimensions. Examples are variations in the number of terminations, variations in the seated height, etc. Variations shall be designated by 2 alphabetic characters starting with the letter AA, AB, etc., in the sequence assigned by the editorial comnittee. -19- - _I_ EIA PDP-LOO 7 = 3234600 0554745 793 = ELECTR
