用人单位这样要求就是无理取闹！

Must be knowledgeable of applicable UL, CSA and CE agency requirements
又不说什么产品，谁知道具体哪一个？

4 Must be knowledgeable of designing complex injection molded components and understand plastic material properties.
5 Must be knowledgeable of applicable UL, CSA and CE agency requirements.
6 Must be knowledgeable of designing sealed assemblies using snap mechanisms, fasteners, adhesives and .
7 Must be capable of defining engineering tests to support designs.  
8 Should have experience with adjacent product areas such as consumer products, video, digital cameras, CD drives
  and be able to apply principles to an industrial environment.  
9 Provide high level "hands-on" mechanical engineering expertise to a variety of products.
10 Position will require understanding of interdisciplinary concepts.
11 Resolve complex technical cross-functional issues regarding component selections, design, testing, reliability,  
   meeting product costing target, and on-going product improvements.
12 Solve diverse mechanical issues, in areas such as product packaging, thermal design, materials selection.  
13 Independently analyze problems to identify and deliver solutions that meet customer needs.  
14 Job content includes some detailed documentation tasks.  
15 Experience in the fabrication of machined, stamped and cast components is desirable.  
16 Familiar with Design for Manufacturing, Design for Assembly and FEA tools a plus.  
17 Prior knowledge of optical and capacitance sensors, electro/mechanical switches, electrical contact/connector  
   design is a plus.  
18 Prior experience designing elastomer seals is a plus.

哦，
  
首先，如果是金属外壳，要保证绝缘，
  
多是用阳极氧化，形成绝缘膜，再进行
  
喷涂。
  
再有，如果是由于高压而导致的爬电间距的危险。
  
绝对是有安规工程师或电子工程师查阅相关资料给你。
  
不可能结构工程师还要查阅电的有关资料。
  
我问你，如果你对电理解不深，搞错了 ，电死人。
  
这个责任是否由你负？？？ 每个人只要做好自己相关的事情
  
就了不起了。

哦，刚才查阅了一些小家电的安规。  
  
  以及电器插座的要求，如下：  
  
  2．4．12  爬电距离（CREEPAGE DISTANCE）：两个导电部件之间或导电部件与器具的边界之间，沿绝缘物表面测得的最短距离；  
  2．4．13  电气间隙（CLEARANCE）：两个导电部件之间或导电部件与器具的边界之间，通过空气测得的最短距离  
  
  我认为如果不搞接插件设计的话，实在没必要知道这些东西！

  
   如是金属外壳，爬电距离不够，用户摸了给电着了怎么办！

  错的很厉害，“爬电间隙”就是安全距离，会出人命的

  
哦，我一直认为“爬电间隙”是指相关电路板设计的，难道和
  
结构又有关联？
  
愿闻其详。

电器安规规定的是工作电压和频率,插头形式....绝缘强度(高压击穿测试),爬电间隙以及人体是否易接触到导电部份等等.   
  
  我看搞结构的知道这个 “插头形式”  
  
  就行啦。至于“爬电间隙”等等，是可以不知道的！！！

要知道的.比如设计一个插座,有些尺寸在UL等安规中是有明确规定的,
特别是与插头相配部位的尺寸.如果开了模再改就麻烦了.
设计尺寸按安规要求修正后才开模比较好.
以前有一个厂的插座过不了安规尺寸,改模工作量很大,
就差没将模具报废了.另开关的触点要过安规,
对材料的选择也很有讲究的
