23、 6-18: General rules for the preparation of outline drawings of surface mounted semiconductor device packages Design guide for ball grid array (BGA) FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnica
24、l committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Te
25、chnical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, govern
26、mental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or
27、 agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international
28、 use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to p
29、romote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly in
30、dicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies.
31、 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property da
32、mage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this pu
33、blication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all
34、 such patent rights. International Standard IEC 60191-6-18 has been prepared by subcommittee 47D: Mechanical standardization for semiconductor devices, of IEC technical committee 47: Semiconductor devices. This standard cancels and replaces IEC/PAS 60191-6-18 published in 2008. This first edition co
35、nstitutes a technical revision. The text of this standard is based on the following documents: FDIS Report on voting 47D/753A/FDIS 47D/758/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. 4 60191-6-18 IEC:2010 Thi
36、s publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all the parts in the IEC 60191 series, under the general title Mechanical standardization of semiconductor devices, can be found on the IEC website. The committee has decided that the contents of this publica
37、tion will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 60191-6-18 IEC:2010 5 MEC
38、HANICAL STANDARDIZATION OF SEMICONDUCTOR DEVICES Part 6-18: General rules for the preparation of outline drawings of surface mounted semiconductor device packages Design guide for ball grid array (BGA) 1 Scope This part of IEC 60191 provides standard outline drawings, dimensions, and recommended var
39、iations for all square ball grid array packages (BGA), whose terminal pitch is 1 mm or larger. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest ed
40、ition of the referenced document applies. IEC 60191-6, Mechanical standardization of semiconductor devices Part 6: General rules for the preparation of outline drawings of surface mounted semiconductor device packages 3 Terms and definitions For the purposes of this document, the terms and definitio
41、ns given IEC 60191 (series) and the following apply. 3.1 ball grid array BGA a package that has metal balls attached to one side of a substrate in a matrix of at least three rows and three columns; terminals may be missing from some row-column intersections NOTE BGA stands for “Ball Grid Array” in c
42、ompliance with the existing standards (See Annex A). 3.2 plastic ball grid array P-BGA BGA with an organic substrate 3.3 tape ball grid array T-BGA BGA with a polyimide tape substrate 3.4 ceramic ball grid array C-BGA BGA with a ceramic substrate 3.5 P-BGA (Flip chip interconnection) BGA with an org
43、anic substrate and a die bonded to a substrate through metal bumps 6 60191-6-18 IEC:2010 3.6 recommended BGA variation BGA variation with the specific dimensions and ball counts as the first choice for production packages other than recommended BGA variations are the least choice for production to a
44、void endless proliferation of BGA outlines. 4 Terminal position numbering When a package is viewed from the terminal side with the index corner in the bottom left corner position, terminal rows are lettered from bottom to top starting with A, then B, C, AA, AB, etc., while terminal columns are numbe
45、red from left to right starting with 1. Terminal positions are designated by a row-column grid system and shown as alphanumeric identification, e.g., A1, B1, or AC34. The letters I, O, Q, S, X and Z are not used for naming the terminal rows. 5 Nominal package dimension A nominal package dimension is
46、 defined as “the package width (E) length (D)”, which is expressed in the tenths place in millimetre. 60191-6-18 IEC:2010 7 6 Symbols and drawings BGA outline is shown in the Figure 1 and 2.

49、rows or columns of balls. (3) The hatched zone indicates the index-marking area where whole index mark will be contained.
