Question

英语翻译
Q1.Please refer to below figure,actual impedance value should be 177ohm for impedance for 6/21mil trace width/gap by impedance simulation as following.then we would like to ignore this requirement of impedance control and test coupon on breakaway tabs.pls confirm
Answer:Keeping the trace width and board thickness unchanged,we suggest to change the spacing of differential pair from 21mil to 4mil so that the impedance 90ohms can be met.
E&E feedback:impedance simulation for differential pair 6/4mils to be 96.8ohm as following,so this,pls confirm the finish impedance value will be 96ohm +/-10%.
besides,pls ignore test coupon on breakaway tabs and it will be added in panel centre.
Pls confirm
Answer:Please maintain impedance at 90ohm +/-10%.E&E can adjust stack up condition to achieve 90ohm
E&E feedback:adjust line width and spacing to 9/4mils can meet 90ohm as following
Answer:Yes ,please proceed
Q2.see below figure shown tolerance is out of our capability,the standard of routing tolerance should be +/-5mil,but we can control the best tolerance +0.2/-0mm or +0.15/-0.05mm,pls confirm it is acceptable.
Answer:Please try to keep +0.15/-0mm
Q3.Please see below figure,this range of tolerance +0.2/-0mil of via inner wall thickness is too tight,pls ignore it and follow 1.0mil min to control.Please kindly help to confirm it is acceptable.
Answer:Yes acceptable
Q4.Please see below figure,for non ICT testpoints,have only top or bot soldermask opening but not have any solder mask opening.we would like to follow gerber to do.
Answer:Please follow gerber data
Q5.Please see below figure,to avoid scratching the PCBs and breaking the package in the process flow,we propose to change the outer corner (4X) as a radius 1.0MM.Please kindly help to confirm it is acceptable.
Answer:Yes acceptable

Answer 1

问题1：请参照以下数值,针对宽对为6/21密尔的导线的阻抗,实际阻抗值应该为177欧姆/间隙阻抗模拟如下.然后我们应该忽视该阻抗控制以及打断点上的附连试验板的要求,请确认.
回复：保持导线宽度和板的厚度不变.我们建议变更微分对的间距,从21密尔到4密尔,这样90欧姆的阻抗就能满足要求了.
电子设备反馈：针对微分对6/4密尔的阻抗模拟为96.8欧姆如下.因此,请确认最后的阻抗值为96欧姆,正负10%.
另外,请忽视打断点上的附连试验板,它会被加在嵌板中央
请确认
回复：请维持阻抗在90欧姆,正负10%.电子设备可以调整叠加条件以便于达到90欧姆
电子设备反馈：调整线宽以及间距到9/4密尔满足如下90欧姆的要求
回复：是的,请进行该操作
问题2：请见如下公差数值,我们无法达到该数值要求,常规公差标准应该是正负5密尔,但我们可以把公差控制在正0.2毫米到0毫米或正0.15毫米到负0.05毫米之间（这是我们最大能力）.请确认是否可接受该做法
回复：请尽量保持在正0.15到0毫米.
问题3：请见如下数值,该贯穿内壁厚度的公差范围：正0.2到0密尔太紧了,请忽视,并使用1.0密尔 最小值 进行操作控制.请帮我们确认这是否可以接受.
回复：是的,可接受
问题4：请见如下数值,针对非信息通讯技术测试点,仅有顶部或底部阻焊层开口,但没有任何焊接淹模开口.我们需要参照格博公司来做.
回复：请参照格博公司的资料.
问题5：请见如下数值,为了避免刮伤电路板,并在进程中弄坏程序包,我们建议更改外交（4X）的半径为1.0毫米.请帮忙确认是否可以接受
回复：是的,可以接受
