11.电容的GND端**直接通过过孔进入内层地，不要通过铜皮连接，后者不利于焊接，且小区域的铜皮没有意义12.电源的连接，特别是从电源芯片输出的电源引脚**采用覆铜的方式连接13.PCB，有大量空白区域，如果信号线的间距足够大，无需表层覆铜铺地。表层局部覆铜会造成电路板的铜箔不均匀平衡。且如果覆铜距离走线过近，走线的阻抗又会受铜皮的影响。14.由于空间紧张，GND不能就近通过过孔进入内层地，这时可通过局部覆铜，再通过过孔和内层地连接。
它的使用特性经国家检测为煤矿用控制电缆导体的长期允许工作温度为70℃，电缆敷设温度应不低于0℃。煤矿用控制电缆允许的弯曲半径：对有铠装或铜带屏蔽结构的电缆应不小于电缆外径的12倍。对有屏蔽层结构的软电缆，应不小于电缆外径的6倍。对无铠装层的电缆应不小于矿用电缆外径的6倍。MKVVR42矿用铠装控制电缆
