请问电路板背面变压器一次侧和二次侧的距离
是遵守IEC60950标准还是IEC950标准啊?
还有UL1950好像也可以是吗?
请问哪位好心人可以发一份标准给我啊?如果可以请注明哪一页呀

好可怜,没人理你.:)至于说要符合哪个标准,要看你的这个产品应用在什么方面,你说的标准都是旧版的了,最新的是IEC60950-1或UL60950-1你所说的距离要求,是需要具体测试之后才能确定的,大概的话8mm应该差不多了,标准在其它帖子里有呀.一份耕耘一份收获哟.
个人觉得8MM也是足够的
不过我拿五六个其他许多ADAPTER拆开了量一下
发现它们的距离竟然有4.5MM,5.6MM,5.4MM的都有哦
但是查以前的标准EN60950或者UL60950
其表格所给出的标准并不是这样
首先,上面所说的ADAPTER的输入是110-220交流市电,输出分别有5-18V
如有高手可照着表格指点一二
即是输入是110-220交流市电,输出大约是12V时
可以参考表格中哪个距离?

ThelatestversionareIEC60950-1,EN60950-1andUL60950-1.Theinsulationdistanceneedstomeasureworkingvoltagetodetermineclearanceandcreepage.Youcanrefertosubclause2.10.
the subclause 2.10 you referd is about IEC60950-1?
is that mean i can determined the distance according to IEC60950-1 2.10?
could you pleased give me a image to direct?
just like i have done before

the image you uploaded is one of the images in the subclause 2.10 of IEC60950-1,
yes,you can determine the distance according to the subclause 2.10 of IEC60950-1,but you should conduct the working voltage test at first.
the CL generally is between 4.0 and 5.0mm, the CR generally is between 5.0 and 8.0mm determined by the working voltage value, Vp and Vrms
