Hi Elke,

Since we are waiting for the new locations for the APV chips, so we are planning upload the design later.

Cheers,
Yi

Dear All,

To follow the spirit of today's discussion on better documenting/more communication through emails, I would like to repeat an question during today's meeting here:

Basing on the current design (keeping T-board/hybrid design to be the same size but only moved connectors to two sides), would it be ok for cable soldiered on T-board to have enough space?
The concern was that the distance between connector and cable solder points was too close to each other and may cause difficulty when connecting T-board and hybrid with cables in the way.
The current dimensions were sent out by Jianing ten days ago and can be found at: https://drupal.star.bnl.gov/STAR/system/files/hybrid_dimension_190506.pdf
The height of a pair of nicomatic connector is 6.2mm. (Steve: Do you think it could be ok for cables?)


PS. the motivation to have connectors on two sides of the T-board, which was discussed during last week's meeting, is to disconnect and connect the connectors more easily.

Best,
Li
