有誰了解PWA的 認證？
部門是負責服務器（ITE類）主板的研發，客戶要求主板做UL，還有PWA(Printed Wiring Assemblies)的UL認可。以前只做過主板的認證，對PWA的認證不了解，看了相關資料，感覺是對PCB組裝的零部件的認可，UL 的產品類別是ZPVI2。不曉得各位大蝦們是否有做過這個的，給小弟提供點線索撒！謝謝先！ 傷心，沒人回復！應該做過PCB單體認證的會了解多一點吧，期待中............ 用的标准是UL796，和电脑主板的认证差不多，LZ你做过主板认证应该得心应手的 呵呵，我知道PCB單體認證用的UL796, 但就是理解不了他和PCB單體認證區別在哪里？
應為主板是用在ITE類產品中，所以我做主板認證時用的標準是UL60950, PCB單體認證我不管，直接找廠家要證書。 如果你的主板当产品申请UL，就不需要再申请PWA了，如果主板放入客户主机一起申请UL，则主板就要申请PWA，这是UL最新的要求！ 如果你的主板当产品申请UL，就不需要再申请PWA了，如果主板放入客户主机一起申请UL，则主板就要申请PWA，这是UL最新的要求！
請問你有關于這個UL要求的文檔么？還有PWA的認證到底是針對主板，還是主板的PCB而言? 如果你的主板当产品申请UL，就不需要再申请PWA了，如果主板放入客户主机一起申请UL，则主板就要申请PWA，这是UL最新的要求！
請問你有關于這個UL要求的文檔么？還有PWA的認證到底是針對主板，還是主板的PCB而言? 我手头没原文件，只有UL审厂文件有如下描述，它包含整个主板（即PCB加在之上的元件），对于那原始文件，在UL网站应该能找到！！
Printed wiring board assemblies (category ZPVI2)
Overview
This program provides traceability for printed wiring board
assemblies. It covers materials and components of assembled
printed wiring boards, including a board itself, when these can only
be identified at a board assembly location. This program is used
when printed wiring boards are assembled remotely from an endproduct
manufacturing location and traceability of a board or its
components is a concern. It is intended to address traceability of a
UL Recognized board and/or components only. All other aspects of
design, spacings, etc., are evaluated as part of the UL investigation
of end-use products.Method of traceability
An assembler is required to keep records to trace the identity of all
materials and components from receipt through storage, inventory,
withdrawal, assembly, packaging and shipping. Printed wiring
assemblies covered under the category ZPVI2 are identified by an
assembler’s name and UL code designation on a part, shipping
container or included specification sheet. Relevant material and
component manufacturer name and type designations are marked
on a part, shipping container or accompanying documentation. In
addition, assemblies covered under this program will also bear the
UL Recognized Component Mark. 十分感謝！ PWB的认证就是PCB的认证
