This section provides acceptability criteria for several special printed board types. The distinctive features of these special printed board types
require supplementing the general acceptability criteria. For each special printed board type, this section outlines where and how the general
acceptability criteria are supplemented. The special printed board types are:
• Flexible
• Rigid-Flex
• Metal Core
• Flush
本节为几种特殊类型的印制板提供了可接受性准则。这些特殊类型印制板的某些特性要求，在通用验收准则之外还需补充若干规
定。对于每种特殊类型板来说，本节指出在通用验收准则的何处及怎样作补充。这些特殊类型板是：
• 挠性板
• 刚挠性板
• 金属芯板
• 齐平板

This section covers the acceptability requirements specific to flexible and rigid-flex printed boards. Parameters not covered in this section are
to be evaluated using the other sections of this document.
The numeric type designator for flexible and rigid-flex printed boards differs from that of rigid printed boards. The various types for flexible
and rigid-flex printed boards are defined as follows:
Type 1 Single-sided flexible printed boards containing one conductive layer, with or without stiffeners.
Type 2 Double-sided flexible printed boards containing two conductive layers with PTHs, with or without stiffeners.
Type 3 Multilayer flexible printed board containing three or more conductive layers with PTHs, with or without stiffeners.
Type 4 Multilayer rigid and flexible material combinations containing three or more layers with PTHs.
Type 5 Flexible or rigid-flex printed boards containing two or more conductive layers without PTHs.
The types referred to in this section on flexible and rigid-flex printed boards will use the definitions above.
The physical requirements for folding flexibility and flexibility endurance are not described in this document. If required by the procurement
documentation, refer to IPC-6013 for details.
本节涵盖了挠性和刚挠性印制板的可接受性要求。本节未涉及的参数可采用本文件其它章节来评定。
挠性和刚挠性印制板的数字类型代码与刚性印制板是不同的。挠性和刚挠性印制板的数字类型代码定义如下：
1型板 包含一层导电层的挠性单面印制线路,有或没有增强板。
2型板 包含两层导电层的挠性双面印制线路，有镀覆孔；有或没有增强板。
3型板 包含三层或三层以上导电层的挠性多层印制线路，有镀覆孔、有或没有增强板。
4型板 包含三层或三层以上导电层的刚性多层和挠性材料组合，有镀覆孔。
5型板 包含两层或两层以上导电层的挠性或刚挠印制线路，没有镀覆孔。
本节有关挠性和刚挠性印制板类型将采用上述定义。
本文件未涉及折叠挠曲性和耐挠折性的物理要求。如采购文件有要求，其详细要求参见IPC-6013。
