1.1 SCOPE
This document describes the preferred, acceptable, and noncon-
forming conditions that are either externally or internally observ-
able on printed boards. It represents the visual interpretation of
minimum requirements set forth in various printed board specifica-
tions, e.g.; IPC-6010 series, J-STD-003, etc.
1.1 范围
本文件描述了可从印制板外部或内部观察到的理想的、可接
受的和不符合的条件,给出了在各种印制板规范,即IPC-6010
系列文件、J-STD-003等文件中描述的最低要求的图示说明。
1.2 PURPOSE
The visual illustrations in this document portray specific criteria of
the requirements of current IPC specifications. In order to properly
apply and use the content of this document, the printed board
should comply with the design requirements of the applicable IPC-
2220 series document and the performance requirements of the
applicable IPC-6010 series document. In the event the printed
board does not comply with these or equivalent requirements, then
the acceptance criteria should be as agreed between user and sup-
plier (AABUS).
1.2 ⽬的
本文件中的目检示意图描述了现有IPC规范要求的具体准则。
为了适当用和使用本文件内容,印制应该符合适用的
IPC-2220系列文件的设计要求和适用的IPC-6010系列文件的
性能要求。在印制线路板不符合这些要求或等效要求的情况
下,验收准则应该由供需双方协商确定(AABUS
1.3 APPROACH TO THIS DOCUMENT
Characteristics are divided into two general groups:
Externally Observable (section 2)
Internally Observable (section 3)
‘Externally observable’’ conditions are those features or
imperfections which can be seen and evaluated on or from the exte-
rior surface of the board. In some cases, such as voids or blisters,
the actual condition is an internal phenomenon and is detectable
from the exterior.
‘Internally observable’ conditions are those features or imper-
fections that require microsectioning of the specimen or other
forms of conditioning for detection and evaluation. In some cases,
these features may be visible from the exterior and require micro-
sectioning in order to assess acceptability requirements.
Specimens should be illuminated during evaluation to the extent
needed for effective examination. The illumination should be such
that no shadow falls on the area of interest except those shadows
caused by the specimen itself. It is recommended that polarization
and/or dark field illumination be employed to prevent glare during
the examination of highly reflective materials.
The illustrations in this document portray specific criteria relating
to the heading and subheading of each page, with brief descriptions
of the acceptable and nonconforming conditions for each product
class. (See 1.4.) The visual quality acceptance criteria are intended
to provide proper tools for the evaluation of visual anomalies. The
illustrations and photographs in each situation are related to spe-
cific requirements. The characteristics addressed are those that can
be evaluated by visual observation and/or measurement of visually
observable features.
Supported by appropriate user requirements, this document should
provide effective visual criteria to quality assurance and manufac-
turing personnel.
This document cannot cover all of the reliability concerns encoun-
tered in the printed board industry; therefore, attributes not
addressed in this issue shall be AABUS. The value of this docu-
ment lies in its use as a baseline document that may be modified by
expansions, exceptions, and variations which may be appropriate
for specific applications.
When making accept and/or reject decisions, the awareness of
documentation precedence must be maintained.
This document is a tool for observing how a product may deviate
due to variation in processes. Refer to IPC-9191.
IPC-A-600 provides a useful tool for understanding and interpret-
ing Automated Inspection Technology (AIT) results. AIT may be
applicable to the evaluation of many of the dimensional character-
istics illustrated in this document.
1.3 本⽂件的使⽤⽅法
本文件中的有关特性可分为两大类:
外部可观察特性(第2章)
内部可观察特性(第3章)
“外部可观察特性”是指那些可在或可从板外表面观察到并
进行评定的特征或瑕疵。在某些情况下,例如空洞或起泡,
其实际状况是一种内部现象,但可从外部进行检查。
“内部可观察特性”是指那些需要对试样进行显微剖切片或
采用其它方法处理才能检查和评定的特征或缺陷。在某些情
况下,这些特征可从外部观察到,但仍需要进行显微剖切,
以确定其是否符合可接受性要求。
为了有效地进行检查,在评定过程中应该保证试样有足够照
明,即除试样本身引起的阴影外,照明不应该在所观察的区
域产生阴影。建议采用偏振光和/或暗场照明,防止在检验强
反射材料的过程中受反光的影响。
本文件中的示意图描述了与每页主标题和副标题有关的具体
则,并以文字了每级产品的可接受条件和不符合条件
(见1.4节)。目量验收准则旨在为评定可见异常情况提供
