1. XXX.的尺寸公差为+/-0.005,这要求是太紧对我们生产,建议公差放松到+/-0.008"。
The tolerance of dimension is specified XXX.+/-0.005" .It is tight for our
production .We suggest +/-0.008" instead。
2.在*.pdf文件中要求外形公差为+/-0.005",建议按IPC 二+/-0.01"
代替。
The profile tolerance is specified +/-0.005" in *.pdf file. We suggest as per IPC class 2,that is to say, it is +/-0.01".
3. 在叠层图中要求板厚公差为+/-0.007",而notes 1中要求板厚公差为+/-0.005",他们是不同的,建议0.062"+/-0.007"是可接受的,因为+/-0.005"对我们来说太难控制了。
The tolerance of the board thickness is specified +/-0.007" in layup detail which is different form NOTES 1
+/-0.005".We suggest 0.062"+/-0.007" is acceptable for +/-0.005" is very tough for us to control.
4.外形公差要求+/-0.1mm,这超出了我们生产,建议按+/-0.2mm
控制。
The tolerance of the outline is specified +/-0.1mm.It's above us. We suggest +/-0.2mm instead.
5. v-cut留厚公差为+/-0.06mm上下偏移公差为+/-0.05mm,这两个公差都太紧,
建议两个公差都按+/-0.1mm控制。
The remain tolerance of v-cut is specified +/-0.06mm and offset tolerance
is +/-0.05mm. they are too tight for us,we suggest both tolerance are +/-0.1mm
instead.
6.孔位公差为0.05mm,这是太紧对我们,建议用+/-0.076mm替代。
The tolerance of the hole position is specified 0.05mm. It's too tight for us, We suggest +/-0.076mm instead.
7. 角度公差为+/-0.5mm,这是太紧对我们,v-cut角度我们将控制在30+/-5
度。
The tolerance of angle is +/-0.5 degree ,it is tight for us , we would
like to control the angle of v-cut within 30+/-5 degree.
8.在1MB5476-01.pdf文件中要求孔到板中心的公差是+/-0.05mm,这是太紧对我
们,建议安IPC二级。
It is special that the tolerance of the hole to board center is
+/-0.05mm in the 1MB5476-01.pdf file,it is too tight for us ,we suggest as per IPC class 2 .
9.要求线宽和线间距公差为+/-0.03,这是太紧对我们,请确认放松到+/-20%。
It stated that conductor width and spacing shall be within +/-0.03(0.001)
of gerber data , it is tight for us , we would like to relax to +/-20%.Pls confirm.
10.Φ3.0的孔径公差要求+0.05mm,这太紧对我们,请确认放松到+0.1/-0mm。
The tolerance of the holes with diameter 3.0mm is required to control
within +0.05mm ,it is tight for us , we would like to relax to +0.1/-0mm.Pls confirm. |
