. v ,please confirm.
上图为我司建议叠构,请确认.
〔9〕问题:Your company have not provided the tolerance of board thickness,please confirm whether we could control it as 1.6mm+/-10%.
贵司没有提供板厚公差,请确认我司可否按1.6mm+/-10%来管控.
. .
. v .
〔10〕问题:We can't find the finish copper thickness and solder mask color in spec ,please provide.
我们在说明书中找不到完成铜厚和防焊颜色,请提供.
建议:Finish copper thickness:1oz, SM color: matte green
完成铜厚1OZ 防焊颜色:哑光绿色
〔11〕问题:Please see Fig1,the number in gerber is different from "HIT-20-001200-001" in spec.
请看图一,gerber中的料号跟说明书中的"HIT-20-001200-001"不相符.
建议:We will ignore this difference and follow the gerber file to produce this board.

我们将使用常用的板材生产,请确认.像KB6160或同等级的板材来代替FR-402.
〔13〕问题:In order to avoid the panel board scraped in process, we would like to change the sharp corner to round angle as R1.0mm.
为了防止板子在生产过程中刮花,我们将尖的角倒角为R1.0mm 的角.
〔14〕问题:See below figure,50 Ohm impedance is controlled in the gerber, but
. .
. v .
the e-mail indicated that had no controlled impedance;Actually, the calculation also cannot reach 50 Ohm impedance values . 见以下图,gerber中要求做50ohm阻抗控制,但邮件中说明不用做阻抗控制。事实上也达不到50ohm阻抗值.
建议:Ignore the impedance control.
忽略阻抗控制.
〔15〕问题:There is no 60
