PCB常见工程咨询中英文对照总结

常见工程咨询中英文对照问题：客户未告知采用什么标准进行制作与检查。

建议：我们按IPC-6012B Class2与IPC-A-600G Class2 做。

建议: 将公差放松到+/-0.15mm.Question: Customer requires “1.60+/-0.10mm” finished board thickness, the tolerance is too tight for six -layer board., it’s hard to control for us.Suggestion: Relax the tolerance to be +/-0.15mm.问题：客户未规定使用何种类型的阻焊油及颜色。

建议: 我们采用普通感光绿色湿油.Question: Customer doesn’t specify solder mask type and color.Suggestion: We use normal green LPI.问题：客户未指定UL 标记与Date code加于何处及以何种方式显示。

建议：见下图，我们将其加于TOP面，以白字显示。

Question: Customer doesn’t specify where and by what display form we should add UL logo and date code.Suggestion: See below picture, we add them on top side and display them by silk letters.问题：客户要求线路表面油厚为30um min，线路拐角位为20um min，此要求太高。

建议: 线路油表面厚与线路拐角位油厚分别放松到15um min 与10um min.Question: Solder mask is required to be 30um min over line and 20um min at corners, it’s too strict. Suggestion: Relax it to be 15um min over line and 10um min at corners,问题：客户未规定镍金厚度要求。

建议：我们按镍厚2.54um min,金厚0.03—0.08um制作.Question: Customer doesn’t specify thickness of Ni and gold.Suggestion: Ni: 2.54um min and gold: 0.03---0.08um.问题：客户未清楚指明层序。

建议：层序为：Question: Customer doesn’t indicate layer sequence.Suggestion: Layer sequence is问题：客户未规定压板结构。

建议：按下图所示做。

Question: Customer doesn’t specify lay-up structure.Suggestion: Follow below picture to do.问题：客户未规定如何对电测试OK的板加注标记。

建议：A）板边划一条黑线。

B）板内盖白色的T印。

Question: Customer doesn’t specify how to take a mark for “E-Test OK” board.Suggestion: A) Mark a black line at edge-board.B) Take a white stamp on board.问题：客户未指定V-CUT标准。

建议：V-CUT角度为30°±5°，余厚为0.40+/-0.10mm。

Question: Customer doesn’t specify V-cut standard.Suggestion: V-cut angle: 30°±5°, residue thickness: 0.40+/-0.10mm。

问题：客户未指明斜边标准。

建议：按下图所示制作。

Question: Customer doesn’t specify bevel standard.Suggestion: Follow below picture to do.问题：请看下图，成品板四个角为直角，运输与包装过程中易造成板间擦伤。

建议：A）将直角改成R1.0mm的圆角。

B）不能更改。

Question: See below picture, four outer corners are rectangular, sharp corners will bring scratching between boards during transportation and packaging.Suggestion: A) Change the rectangular corners into R1.0mm ones.B) Take no change.问题：板上P/N为ABCD，但客户资料上为EFG。

建议：A）将板上的P/N改为EFG.B）将文件资料上的P/N改为ABCD。

C）不予理会。

Question: Part number is ABCD on board, but EFG in documents.Suggestion: A) change ABCD into EFG on board.B) change EFG into ABCD in documents.C) Let them be.问题：客户资料上版本为REV. A，但板上为REV.B。

建议：A）将板上版本改为REV. A。

B）将资料上版本改为REV. B.C）不需做任何更改，允许版本不一致。

Question: Reversion No. is A in documents, but B on board.Suggestion: A) Change A into B on board.B) Change B into A in documents.C) Not take any change, let them be.钻孔部分问题：客户未规定孔径公差。

建议：VIA Hole：+0.08/-0.40mm PTH：+/-0.08mm，NPTH：+/-0.05mm，Slot：width+0.08mm，length+/-0.10mm。

Question: Customer doesn’t specify tolerances for holes.Suggestion: VIA Hole：+0.08/-0.40mm PTH：+/-0.08mm，NPTH：+/-0.05mm，Slot：width+0.08mm，length+/-0.10mm。

问题：客供图纸上“A”处数据与“B”处数据相矛盾，请看下图。

建议：a）按“A”处数据做。

b）按“B”处数据做。

Question: See below picture, the data marked “A” is conflict with “B” on the mechanical drawing.Suggestion: a) Follow the data marked “A” to do.b) Foll ow the data marked “B” to do.问题：见下图，图纸上“A”处数据公差+/-0.05mm，超我司能力。

建议：将其放松到+/-0.10mm。

Question: See below picture, the tolerance(+/-0.05mm) marked “A” is out of our capability.Suggestion: Relax it to be +/-0.10MM.问题：图纸上“A”处数据为100.25mm（请看下图），Gerber中此处实测数据为100.34mm。

建议：a）按图纸做。

b）按Gerber做。

Question: See below picture, the data marked “A” is 100.25mm on drawing, but the factualvalue is 100.34mm in Gerber.Suggestion: a) Follow drawing to do.b) Follow Gerber to do.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 is 0.8mm, it’s impossible to rout the slot out yet.Suggestion: Change the slot width into 0.8mm.问题：请看下图，一个0.86mm的孔与一个1.23mm的孔相互重叠。

建议：A）删去0.86mm的孔。

B）删去1.23mm的孔。

Question: See below picture, one 0.86mm hole overlaps another 1.23mm hole.Suggestion: A) Delete 0.86mm hole.B) Delete 1.23mm hole.问题：请看下图，两个相同大小的孔部分重叠。
