NOTE 6 The values v, w are stipulated as v or w M without A, B as a datum line, and eliminate datum A and datum B from figure 1a. The reasons are as follows. a) Generally, in the
42、 case of ceramic packages, a tolerance of the outside dimensions is wider than that of plastic moulded package. Therefore, the lead true position based on ceramic body dimension is a rather large value like 0,6 mm, generally. These large values v and w are not useful for users. b) E and D, the packa
43、ge outside dimension of G-QFP, do not include seal mismatching and glass protrusion according to note 4, so it is meaningless to specify E and D as datum planes. c) In the semiconductor industry, QFP type packages are handled not by package body, but by the tip of the lead frame, in general. For ins
44、tance, QFP is handled in electrical tests or mounting onto printed circuit board by lead frame as a base point, not by package body, especially for a high-pin-count/fine-pitch QFP. Therefore, it is not so significant to stipulate package width/length as a datum line. NOTE 7 These values include the
45、thickness of finish plating. NOTE 8 Since in the G-QFP the part corresponding to this dimension is not the outermost side of the package, the seal mismatching and the glass protrusion are not included, and only the standard values are stipulated. NOTE 9 The pin layout is determined as follows. E D i
