[求助]关于怎样做Bad mark? [复制链接]

各位老兄,YAMAHA的Bad mark 应怎样做?

在PCB INFO里先做Bad mark 的坐标,然后在MARK INFO里做坏的MARK的资料.记的MARK资料是不反光的.然后优化就行了.

BadMark can be structured into your design library as a "Part" -- this will ease your future designs.

method: badmark could use to methods to build into the PCB --
1. tab: you break the tab to identify the bad board
2. fiducial-like: large pad similar to fiducial marks.   you black it out to identify the bad board

location: on a panelized board, BadMark can be located in two positions --
1. by the piece board -- local -- typical for badmark tab
2. by the panel edge -- global -- typically use fiducial type

good luck

one more: bad mark is not very unique to certain placement machine.

among Juki, Sanyo, Panasonic, Fuji, Siemens, the above recommendations work
