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.
本节盖了齐平印制板的可接受性准则。在齐平印制板中,板表面、和其它性能的可接受性与常规的面及双面印制板相同
本节所及的是对齐平印制板的评定有要作用的参数
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.
齐平路要求体表面和基材表面必需处在面上。
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.
体与基材或所绝缘材料表面齐平
Acceptable - Class 1,2,3(可接受条件 - 1,2,3级)
Conductor is not flush but meets the minimum requirements.
齐平,但足最低要求。
Nonconforming - Class 1,2,3(不符合条件 - 1,2,3级)
Defects either do not meet or exceed above criteria.
缺陷不符合或出上述要求。
