Hi Hansheng,

  Thanks for the documents.

  The latest documents of dimensions and CAD files for hybrids and T-board can be found in the attachments. Please double check.

  Some dimensions have been updated, which are highlighted in red in the document ("190712_Dimensions of hybrids & T-board in new design.pdf") and are also listed below.

  T-board:

  1. The diameter of four mechanical holes is increased to 2 mm.

  2. The location of two mechanical holes is modified. The distance from them to the long side is increased from 1.55 mm to 5.55 mm.

  Inner hybrid:

  1. The tail length is increased by 3 mm, as there is a height difference between the inner hybrid and T-board.

  Since the height difference is 7.45 mm and the height of two connected male and female connectors is about 6.2 mm, the tail length must be increased by 1.25 mm at least. In current design, the tail length is increased by 3 mm to ensure the connection.

  Outer hybrid:

  No change.

  But I am a little confused. The height difference between T-board and outer hybrid seems to be 4.1 mm (Am I right?), but the height of two connected connectors is about 6.2 mm. Is that enough to place the connectors?

  Please correct me if there is any misunderstanding.

  Thanks!

Best,

Jianing
