投板用英语怎么说？

tape out？

load into production
prototype build
we will build the PCB per your drawing/spec etc...

send out for manufacture
build up for prototype
想怎么说就怎么说，反正大家都懂。

我们用
PCB kick off，或者release

Release GERBER data

我们就是release gerber

realease gerber 感觉上是设计结束， release gerber to prototype or production would be better.

呵呵，都和写论文似的精确啊

呵呵，设计结束，是PCB layout release.
投版，我们用的是Gerber release或者manufacture gerber release。
简称MFG release
