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!!* ^5 r& t- D7 V! W" ]) L

PWB的认证就是PCB的认证作者: bujust 时间: 2011-11-11 15:57
很疑惑的是既然我主板整体都做了UL认证了, 我还需要做PWA认证。2 w" b9 n0 [- ^1 ]
主板的UL认证是否就表示了PCB,components, connects 等主板上使用的原材料已经满足了UL的要求呢? 或者说我用的这些材料都已经在你们UL报备认可的了。% ]6 h" `6 V) k: g( \3 ^

UL的traceability就是圈钱要求,太不合理了。 + G) _. p0 E- t( ~6 r' y* l2 o5 j另外,所谓的PWA认证就类似于IT产品中要求的VZQC2的半成品认证。好无奈啊! 变法的“抢”钱!
