Fab documentation #19

Closed wisxxx closed 3 years ago

wisxxx commented 3 years ago

What is the core material?

Is there a fab drawing showing outline, hole, and key component dimensions?

AlphaBetaPhi commented 3 years ago

Hi @wisxxx,

Thank for your interest in the project. The core/prepreg materials are listed in the layer stack up image found in Time-Card/FAB/V1

wisxxx commented 3 years ago

I don't see a core material - only pre-preg (2113).

Hi @wisxxx,

Thank you for outlining this, we will update fab documentation to address this.

You may use FR4 for this design which allows access to many fab shops to build the time card. Additionally, you may alter the design for another core material if needed by additional changes or tighter requirements to high speed signals.
