8. 3-9 画面左上角白色方框内的 4 个圆圈表示 PCB 或钢网的 4 个 Mark 点。一般我们选
择 2 个对角的点进行匹配即可。通常情况下，为了在搜索马克点时 Mark 点能出现在
CCD 的视域里，我们需要在选择匹配的 Mark 点时输入 Mark 点到边的距离,如图 3-10，
3-11 所示。
The four cycles in the white box which is in the top left corner of pix 3-9 represent
the four mark points of PCB or stencil. Usually select two diagonal points to match.
In general, in order the mark point can exist in the view of the CCD when search it,
operator needs input the distance data between mark point and side when select
the matching mark points. See pix 3-10 and 3-11.

图 3-10 是 PCB Mark 点到边的距离，输入后搜索 PCB Mark 点时，所选的 PCB Mark
点能直接出现在视域里；
It is the distance between PCB mark and side show in the pix 3-10. Input the distance
date when search the PCB mark point, the selected PCB mark point can show in the
field of vision.
