请教各位， 怎样才能把PCB的压合层一层一层的剥离下来。

支撑孔（supported hole）和非支撑孔(non-supported hole)的定义最初来自美国
50-60年代。当时主要用来区分PTH（镀通孔）和非PTH（非镀通孔）。
这些定义一直流传到现在，在一些标准和文件中被翻译并一直延续使用。例如
IPC-A-600和610等文件。
以上是来自行业内国外专家和IPC-A-600美国专业讲师的解释。
现在通常指孔内有电镀层的孔和没有电镀层的孔。

PCB上的孔无非是PTH和NPTH，前者主要用于元件安装孔和导通孔；后者主要是定位孔
和PCB安装孔。在DFM中，并不关心什么是支撑孔、什么是非支撑孔。只要明白我们做
什么，留出合理的间隙即可。
如果简单理解，可以认为装元件的孔为支撑孔，不装元件的孔为非支撑孔。这样就比
较明确了。

有的PCB板的支撑孔&非支撑孔是根据PCB板的PTH物料的特性区分的

我们工厂是按照:
1、 支撑孔：需要通孔吃锡的板子，一般为双面板或者多层板
2、 非支撑孔：只是单面吃锡的，焊点没有通孔，一般为单面板

主题: [TGAsia] 支撑孔和非支撑孔的定义
各位专家，
请教一下：PCB行业中支撑孔和非支撑孔的定义具体是如何区分的？目前个人掌握的也
不唯一，有的说按电镀性质区分，有的说按孔的功能区分。
目前在IPC-A-600H和IPC-6012C中都出现过支撑孔和非支撑孔的名称，但IPC-T-50H中
也没有具体的定义，特请教各位！
