s-ATA的芯线有没有做平行粘连结构?如果有做的,讨论下注意问题好吗?

我有试过，但电容很难控制。

联颖刚开发时是这样做的,但很不方便后来改了!

UL不允许的

ouyang:
UL不允许的

能提供一点左证吗?谢谢!

希望继续讨论,各位都可以发表下自己的看法!

不好控制

工艺上怎么个不好控制? 发炮度? 押出难? 还是怎么着?

810707 --- 2008-05-28 10:07:02

我们以前主要是押出难!可能是设备的原因吧!用的是传统机头!

如果使用免对排线机头这样作业还是很顺利的

如果有UL marking最好是不让他们发现

发泡的应该很难控制吧。Belden有专利但是 是 Lan Cable 比较好控制。

押出后受压力不同可能更容易导致 Skew Fail；

 

余 兄 如果有UL marking最好是不让他们发现  和UL 有什么关系？

10楼也有提到,如果用2725的话,2725的结构芯线不允许用并线的,这个你可以去问你们厂那个UL查厂的就可以了,他可以给你比较详细的解释,听说曾经东莞有一家给查到了这个问题,而且后果比较严重.

我們以前用的就是並來的很難做

我们印的UL21149!

对于FoamPE绝缘芯线,常用的style为1598,这些只能生产单芯结构,是不允许这样生产的

当然,如果你们公司有相对应的结构认证,还是没问题的

請問樓上：FoamPE絕緣芯線用UL1598和UL1589有何區別?

我主要是想問：May be crosslinked．是什麼意思？

如果使用並行粘連結構就使用什麼號碼？

余澤平前輩：

　　　　　你說用免對排線機頭好做．是做的發泡PE嗎？請提供一下機頭供應商，模具供應商．

謝!
