These are Batch 8th terms . Please review them and give your opinions.  



 

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。

  

Maximum Material Condition (MMC) 最大实体情况 (MMC)      22.0747

A drawing defining certain characteristics of the printed board, such as
material within the stated limits of size.

定义特定印制板特征参数的图纸，如在定义实体的尺寸界定范围。

 

Mealing                                              麻点
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。

 

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树脂织物上分离的情况 (通常表现为基材表层下面出现白色离散
斑或“十字叉”，一般与热应力有关) (参见“微裂纹，基材”)。

 

Mechanical Stress                            机械应力         95.1755

To subject a mechanical component to a process of physical stress. 

物理过程对机械件产生的应力。

 

Mechanical Wrap                              机械卷包         75.0749

The physical securing of a wire lead or component lead around a solder
terminal. 

导线或元件引脚可焊端的物理封装。

 

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.)

A string of characters encoded into a bar code symbol of a specific length.


一串字符编译为特定长度的条形代码。

 

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。

 

Metal Core Printed Board                金属芯印制板       61.1587

A printed board having a metal core as the support for the printed board
structure, usually used as a heat sink or power supply grounding layer.

以金属芯为结构支撑的印制线路板，通常用作为散热片或电源接地层。
