我把您的问题发到英文e2e上了,因为这款器件太老了,不确定是否还有工程师支持。请关注下面帖子的回复。

非常抱歉,回复晚了,刚得到e2e工程师那边的回复。
I have checked this with our packaging experts and the loop heights for the internal wires can be different and a 2D Xray will not show the correct distance and there should not be any issues here. There are also checks that are done in our assembly process that should verify that the distance between the pins is correct.
