问题：请看下图，红色圆圈圈住的
Slot
宽度为0.65mm
，长度为
12mm
。由于长度比较长，不宜钻
出。如果锣出 ，其宽度又比最小锣刀的直径（
0.8mm
）还小，也无法锣出。

建议：将
Slot
宽度改为
0.80mm
以便锣出。

Question: See below picture, the slot (which is marked with red circle) size is 0.65mmX12mm. As the slot
is very long, we have to rout it out, but our smallest rout bit

2mil
。







B
）将两孔
Siz e
分别缩小
0.05mm
，即做成
0.95mm
与
2.05 mm
。

Question: See below picture, the distance is only 10mil between 1.00mm hole marked “a” and 2.10mm
hole
marked
“b”
(it’s
14mil
min
distance
for
our
normal
workmanship),
the
close
distance
will
easily
cause

shorts between the two holes in plating process.
