sheet 與 panel的區別
剛剛在看IPC-650 關于PCB變形的問題，發現分不清楚
sheet 與 panel的區別 哪位PCB高人指點一下
1.1DefinitionsBowandtwistaredefinedinIPC-T50.
The definitions are repeated in this test method forconve-nience.
1.1.1Bow(Sheet,Panel,or Printed Board)The devia-tion from flatness of aboard characterized by aroughly cylin-dricalor spherical curvature such that,if the product is rect-angular,its four corners are in the same plane(seeFigure1).

Panel 一般做面板讲, 我们看到到的经常只有一个面, 或者从这个面读出读数; 通常是一个组装后的部件;
而SHEET, 非常薄的板,或什么片, 通常可以看到两个大的面,厚度较薄, 没有装配什么东西, 通常只是一个零件.
我不是电子专业的,不敢确定全对.
