Acceptable - Class 1,2,3(可接受条件 - 1,2,3级)
• Wicking, radial cracks, lateral spacing or voids in the hole-fill
insulation material does not reduce the electrical spacing between
adjacent conductive surfaces to less than 100 µm [0.003937 in].

Target Condition - Class 1,2,3(⽬标条件 - 1,2,3级)
• Complete bond on both sides.
• 两侧均完全粘接。
Acceptable - Class 1,2,3(可接受条件 - 1,2,3级)
• Interconnection separation not more than 50% of the non-copper
core thickness. If copper clad core is used it shall not have any
separation in the copper portion of the interconnect.
• 互连处的分离不大于非铜金属芯厚度的50%。如采用覆铜金
属芯,则在互连处的铜部分不应当出现任何分离的现象。

This section covers acceptability criteria for flush printed boards. In flush printed boards, the surfaces, holes and other parameters for accept-
ability are the same as in standard single-and double-sided printed boards. This section covers the additional parameters that are important to
the evaluation of flush printed boards.
本节涵盖了齐平印制板的可接受性准则。在齐平印制板中,板表面、孔和其它性能的可接受性与常规的单面及双面印制板相同。
而本节所涉及的是对齐平印制板的评定有重要作用的附加参数。
4.3.1 Flushness of Surface Conductor(表⾯导体的平整性)
The application of flush circuitry requires that the conductor surfaces and the base material be essentially in the same plane.
齐平电路要求导体表面和基材表面必需处在同一平面上。
Target Condition - Class 1,2,3(⽬标条件 - 1,2,3级)
• Conductor is flush to the base material or surrounding insulating
material surface.
• 导体与基材或所围绕的绝缘材料表面齐平。
Acceptable - Class 1,2,3(可接受条件 - 1,2,3级)
• Conductor is not flush but meets the minimum requirements.
• 导体虽不齐平,但满足最低要求。
Nonconforming - Class 1,2,3(不符合条件 - 1,2,3级)
• Defects either do not meet or exceed above criteria.
• 缺陷不符合或超出上述要求。
