因为各种电子元器件，内部暴露在外，容易损伤，也不容易包装、运输、使用，所以很多厂家经过多年的探索，把各种电子元器件外面用一些绝缘非绝缘材料包裹起来。就是封装。
基本的封装材料有金属，陶瓷，塑料。
不同的封装形式还给起来不同的名字，大部分是根据外形尺寸区别的：
封装的分类
具体各大引擎搜索“封装”，我们课程是索引大于解释，方向路线为主，知道从哪里获取资料就够了。
1.12.2 电路板 封装库
我们经常听到PCB这个词，去搜索也能知道大概，印刷电路板的意思。
电路板给各个电子元器件一个骨架，不至于连在一起东倒西歪，类似于楼盘的地基。
早期的电路板是各种孔，因为原先的电子元器件都是带金属引脚的，这样装在电路板中，再焊接上就很牢固。
后来发现，这种金属引脚的电子元件，组装困难，很多时候必须人工操作，效率很低。后来发明了贴片工艺。
电子元件的封装从直插件变成了贴片件。从此有了SMT的说法，叫做表面贴装技术。
SMT就是把贴片的电子元器件焊接到电路板上的技术。
SBS-6AH
Because various electronic components are exposed internally, easy to damage, and not easy to package, transport, and use, many manufacturers after years of exploration have wrapped various electronic components with some insulating non-insulating materials. It’s encapsulation.
The basic packaging materials are metal, ceramic, plastic.
Different packaging forms are also given different names, most of which are different according to the outline size:
Classification of package
Specific to the major engine search “package”, our course is more index than explanation, direction route based, know where to get information is enough.
1.12.2 Circuit Board Package Library
We often hear the word PCB, to search can also know the meaning of the printed circuit board.
The circuit board gives each electronic component a skeleton, so that it is not linked together, similar to the foundation of the real estate.
The early circuit boards were all kinds of holes, because the original electronic components were with metal pins, so that they were installed in the circuit board and then welded on it was very strong.
It was later found that the electronic components of this metal pin were difficult to assemble, and many times they had to be manually operated, which was very inefficient. Later, the patch process was invented.
The packaging of electronic components has changed from straight plug-ins to patch pieces. Since then, there is the word SMT, called surface mount technology.
SMT is the technology of welding the electronic components of the patch to the circuit board.
