多层线路板 技术领域
[0001] 本申请涉及电路领域, 尤其涉及一种多层线路板。
背景技术
[0002] 在印制线路板领域, 由三层板件构成的复合型线路板一般称作多层线路板。 多层线 路板的内层板件制作完成后, 需要与外层板件一起进行压合操作, 从而形成多层线路板, 传 统的多层线路板的对位方式, 一般是在板件上开设单一的对位孔进行对位, 这种方式易造成 对位方向不清和偏差大小不易确定的问题。
发明内容
[0003] 本申请旨在至少在一定程度上解决上述技术问题之一。
[0004] 本申请提供一种多层线路板, 包括: 设置有外层线路的外层板件, 以及置于该外层 板件内侧且设置有内层线路的内层板件, 所述外层板件在其对角线的两端位置设置有第一对 位孔, 所述内层板件在其对角线的两端位置设置有第二对位孔, 所述第一对位孔与该第二对 位孔位置相对应。
[0005] 进一步地, 所述第一对位孔与第二对位孔的外周设有孔盘。
[0006] 进一步地, 所述孔盘呈圆形阶梯状。
[0007] 进一步地, 所述对位孔直径为 0.8-1.5mm。
[0008] 进一步地, 所述对位孔直径为 1.0mm。
[0009] 本申请的有益效果是:
通过提供一种多层线路板, 其在外层及内层板件对角线两端位置, 对应设置有一对对位孔, 使上下板件之间能实现电路图形的精准对位, 另外, 由于对位孔外周设有孔盘, 采用对位孔 与孔盘的尺寸关系, 可以确定对位偏差大小。
