27、uctor device packages 1 Scope This part of IEC 60191 gives general rules for the preparation of outline drawings of surface-mounted semiconductor devices. It supplements IEC 60191-1 and IEC 60191-3. It covers all surface-mounted devices discrete semiconductors with lead count of greater or equal to
28、8, as well as integrated circuits classified as form E in Clause 3 of IEC 60191-4. 2 Normative references The following referenced documents are indispensable for the application of this document.

31、 definitions apply. 3.1 seating plane plane which designates the plane of contact of the package, including any stand-off, with the surface on which it will be mounted NOTE This plane is often used as the reference plane. 3.2 reference plane plane parallel to the seating plane at a distance A3 above
32、 seating plane (does not apply to leadless package) NOTE 1 The distance A3 is known as the reference plane distance. It determines the terminal projection zone (see Figure 1). NOTE 2 This distance is a theoretical dimension which is not related to any feature of the package. Its value is chosen for
33、each package so the length of terminal projection zone Lpis a good approximation of the terminal length used for mounting, e.g. the length of the part of the terminal that is soldered to the substrate. BS EN 60191-6:200960191-6 IEC:2009 7 3.3 terminal position area maximum area on the seating plane

36、NOTE 2 The true positions of the centres of the terminal position areas are located on a grid with a modulus e / eD or e / eE NOTE 3 The pattern of terminal position areas does not include tolerances stemming from mounting substrates (printed board) design and placement machine accuracy. 3.5 coplana
37、rity of terminals profile tolerance controlling the location of the crowns of the bottom terminals with respect to the seating plane NOTE In all the other cases, the requirement for coplanarity of terminals is clarified by a note. 3.6 datum geometrical established planes for controlling the toleranc
38、e zone NOTE Datum S should be established by seating plane. 4 Design rules The outline drawing of a surface-mounted semiconductor device package shall comprise in the given sequence: the drawing (strictly speaking); the tables of dimensions; the notes to the tables and the drawings; the codification
39、. The drawing shall conform with the general rules for drawings laid down in IEC 60191-1, Clause 4 and Clause 5, as well as with the specific definitions of Clause 3 above. The following, Clause 5 and Clause 6 give, respectively, the tables of dimensions to be specified and the notes to be called, w
40、here relevant. Supplementary dimensions and notes may be added when required. BS EN 60191-6:2009 8 60191-6 IEC:2009 The codification of package outlines shall be in accordance with IEC 60191-4. 5 Dimensions to be specified Crosses in the Table 1 and Table 2 indicate where values have to be specified
41、. In the auxiliary right-hand column, a code indicates for which outline families each dimension is generally relevant, as follows: L: leaded packages packages with gull-wing leads for example; QFP, SOP,TSOP F: folded lead packages packages with J-bent leads for example; QFJ, SOJ P: leadless package
42、s packages with no leads for example; QFN B: ball grid array packages packages with ball leads for example; BGA 6 Notes Notes referred to in the tables and in the drawings appear after Table 2; in the auxiliary right-hand column, a code indicates for which outline families each note is generally rel
43、evant (with the same code as in Clause 5 above). For each particular outline package or package family, the applicable notes shall be numbered sequentially from 1 in the order they are in the tables and then on the drawing.
