 Metal-Clad Base Material                覆金属箔基材  41.1609

Base material covered with conductive foil on one or both sides. 

基材的一侧或两侧以导电箔包裹。

Measling                                            白斑                 55.0748

A condition that occurs in laminated base material in which internal glass fibers are 

separated from the resin at the weave intersection. (This condition manifests itself

 in the form of discrete white spots or "crosses" that are below the surface of the 

base material. It is usually related to thermally-induced stress.) (See also "Crazing, Base Material.")

▲ 层压基材内，玻璃纤维从编织交点的树脂上分离的状态(这种状态通常表现为

基材表层下面出现离散的白色斑点或“十字叉”，一般与热应力有关) (参见“微裂纹，基材”)。



Meniscus                                           弯月面             92.0750

The contour of a shape that is the result of the surface-tension forces that take place during wetting. (See Figure M-2.)

在焊接润湿时由于表面应力所产生的焊接形状轮廓。



▲由于在焊料润湿过程中产生的表面张力而形成的外形轮廓。



Mealing                                                                     76.1814

A condition in the form of discrete spots or patches that reveals a separation at the interface between a conformal coating and a base material on the surface of a printed board, on the surface of an attached component, or both.

覆形涂层和在印制板上或元器件上的基材间存在表示分层的离散斑或碎片的情况。

▲斑片---以离散的斑点或碎片形式出现的状态，它表现为覆形涂层与印制板表面或被焊元器件表面界面上的分层。



 



Master Drawing                                 标准图纸                26.0744

A control document that shows the dimensional limits or grid locations 



that are applicable to any and all parts of a product to be fabricated,



 including the arrangement of conductors and nonconductive patterns 



or elements; the size, type, and location of holes; and all other necessary information.



用以描述投产产品部分或全部元件的尺寸范围或网格位置的作业图纸，



包含导体和非导体元件的排布，孔的形状、形式和位置，还有其他必须的信息。



▲布设总图---用以描述被制作产品所用任何和所有要素的尺寸范围或网格位置

的控制文件，包括导体和非导电图形或元素的排布，孔的尺寸、类型和位置，

以及所有其他必要信息。

说明：在现有的国家标准中“Master Drawing    ”的中文意思是“布设总图”。我认为最好不要将人们

头脑中已建立的概念词汇转换成其他的字或词。除非由原则性错误。

▲斑片---以离散的斑点或碎片形式出现的状态，它表现为覆形涂层与印制板表面或被焊元器件表面界面上的分层。

说明：在现有的国家标准中“麻点 ”的英文是“pit”
