Minimum dielectric thickness is the maximum material condition used for the electrical voltage dielectric strength requirements.
压介质强要求的最大材料条件。
Target Condition - Class 1,2,3(⽬标条件 - 1,2,3级)
The minimum dielectric thickness meets the requirements of the
procurement documentation.
足采文件的要求。
Acceptable - Class 1,2,3(可接受条件 - 1,2,3级)
The minimum dielectric thickness meets the minimum require-
ments of the procurement documentation.
If the minimum dielectric spacing and the number of reinforcing
layers are not specified, the minimum dielectric spacing shall be
0.09 mm [0.0035 in] and the number of reinforcing layers shall be
selected by the supplier.
Low profile copper foils should be used with dielectrics below
0.09 mm [0.0035 in].
足采文件的最低要求。

应该使用质低于0.09mm[0.0035in]的低粗糙度铜箔
Nonconforming - Class 1,2,3(不符合条件 - 1,2,3级)
Defects either do not meet or exceed above criteria.
缺陷不符合或出上述要求。
Notes:
1: Products designed for transmission line impedance applications may have special requirements and measurement method specified on
procurement documentation.
2: When the nominal dielectric thickness on the drawing is less than 90 µm [3,543 µin], the minimum dielectric spacing is 25 µm [984 µin]
and the number of reinforcing layers may be selected by the supplier.
注:
1. 传输线应用设计的产品,可在采文件中规定特要求和测量方法。
2. 当图上的标度小90μm[3543μin]时,则最间距25μm[984μin]层数可以由供应商选择
