Second Electrical Module (ABC130)

Since the first electrical module got damaged in December, 2017. A second electrical module with v1.1 hybrids (and also v1 power board) had to be made and shipped to BNL. Thanks to previous experience, we were able to make this module much faster. But there were a few changes in terms of assembly, comparing to the first module:

  • Changed to UV gluing for chips onto hybrids with a dispenser; This way is considered as standard for modules building with v1.2 hybrids (as well as v2 power boards).
  • A dispenser was used to distribute gule on hybrids.
  • Then a flex of 10 UV LEDs was placed next to the hybrids to cure the glue, which usually takes 10 minutes (to be safe, 30 minutes for second electrical module).
