关于UL8750-2015距离的问题
7.8.2 Minimum spacings on printed wiring boards and for board-mounted components shall be not lessthan those shown in Table 7.5 between:
a) Uninsulated live parts of opposite polarity,
b) Uninsulated live parts and a grounded dead-metal part, and
c) Uninsulated live parts and an accessible dead-metal part.
7.8.2 里面说的是不同极性距离，但是在table 7.5里面根本没有啊
table 7.5 里面的这些是什么意思
Live parts reliably positioned AND
insulator with CTI ³ 600 (PLC = 0)b; i.e.:
adjacent PWB traces, lead pins of
semiconductors to their mounting, etc.
Live parts reliably positioned AND
insulator with CTI ³ 100 (PLC £ 4)c; i.e.:
adjacent PWB traces, lead pins of
semiconductors to their mounting, etc.
