很难找到与验收准则很多案当本标准中的
照片或示意图与文字说明不一时,以文字描述为优先,并
应该遵文字说明的规定。
应该 意到本文件中某些照片可能时用表示一示
例的种状况。因此,本文件的使用要特别注意每节的主
题,以免产生解。
对于给定的不符合条件,应该理解为凡缺陷程低于不符合
条件的所有其它条件是可接受的。因此,例如某准则规
定不符合条件为表面50%出现麻点,这意味着在该级的印
制板中,要产生麻点的表面50%,对该特性说是可
接受的。显,对于1级板是不符合的状况,意味着对于2
板和3级板也均为不符合;同样,对于2级板是不符合的状况
味着对于3级板是不符合的状况。
检验员不应当对所检验产品归属哪一级作出选择。在作出
接受和/或不符合决定时,必须有意地遵文件优先顺序
在所有情况下,应该检验员提供确定交付检验产品
一级的文件。
与该文件关的目视检验程和要求,应当与所适用性能规
范的要求
果发冲突应当采用下列优先顺序
1. 文件(如有,包括针图的例外条件)
2. 映客详细要求的采文件(如图)
3.
户指定的其它文件
4. 户要求引用的最产品的性能规范,例如IPC-6010系列
文件
5. 本可接受性文件。印制板应该具有一的质量,并应当
IPC-6010系列文件的规定。
IPC-6010系列文件规定了印制板的最低可接受性要求。
文件,即IPC-A-600,则是为上述要求提供图示解的一种
及补充文件,不推荐用作印制板生产或采的性能规范。
IPC-A-600可作为检验支持性文件。它没有规定对在制品的检
频次和对最产品的检验频次时,没有规定所允许
的不符合的制程示的量,没有规定对缺陷的修/
允许次数
对适用特性进行目视检查应当3个屈1.75

倍数逐步调高直至40)以确其是否为缺陷。对于
尺寸检验,例如间距宽度的测量,可能要求采用其它
倍数和使用有字线或刻度线的仪器,以便能对规定的
尺寸进行确测量。合或规范可能对倍数有其它要
求。
应当100倍数下对内部的铜箔镀层完整

This section addresses those characteristics which are observable from the surface. This includes those characteristics that are external and
internal in the printed board but visible from the surface as follows:
Surface Imperfections such as burrs, nicks, scratches, gouges, cut fibers, weave exposure and voids.
Subsurface Imperfections such as foreign inclusions, measling/crazing, delamination, pink ring and laminate voids.
Imperfections in Conductive Pattern such as loss of adhesion, reduction of conductor width or thickness due to nicks, pinholes, scratches,
surface plating or coating defects.
Hole Characteristics such as diameter, misregistration, foreign material, plating or coating defects and scratches.
Marking Anomalies including location, size, readability, and accuracy.
