你的线盘绕组有没有与托盘接触?如果有接触需做750度灼热丝.见如下标准.5 n# O, q) ^! D: q# Y( `

一般的线圈都是与托盘接触的，我们也是做750作者: s04052 时间: 2009-10-15 14:15
主要现在我同事认为线圈是一整根绕在托盘上的，并没有与托盘进行电气接触，所以就认为不需要做测试，是否正确呢？作者: sclongwar 时间: 2009-10-15 14:46
这个需要做测试的，你的线圈和托盘是有接触的。作者: junpi 时间: 2009-10-15 16:46
托盘只要与线圈接触，或者与线圈的距离小于3mm，就必须进行750度灼热丝测试作者: okjun 时间: 2009-10-15 16:49
