Vaporized Copper Stiction

August 25, 2021 Hosted by Parker Dillmann, Stephen Kraig

Stephen starts to finialize the hardware of his tube amp bias test system and Parker looks into Jiva Materials, a new type of PCB substrate.

Bias Test system update

  • Happy with the two A/D Converters. Got *all* channels running

  • Made a simple breakout board to be able to access all the pins easier

  • 16 pin IDC cable is holding up to 450V seemingly ok – real test will be with all signals

  • Resistor measurement was adjusted slightly

  • Checked against 4 multimeter and getting values “in range”

  • Next steps

    • Finish a first version of the arduino code
    • Merge the skipi communication with my code
    • Solder into an actual amp to get real world values
    • Schedule next python thing

Jiva Materials

  • “The World’s First Fully Recyclable PCB Substrate”
  • See more information
  • PCB board that when soaked in hot water starts to delaminate
    • Jiva is in the process of ensuring that Soluboard® is compatible with aqueous PCB fabrication processes. Jiva is also engineering Soluboard® to be resistant to high humidity environments.
  • No technical specifications yet
  • Circuits/metals are applied in traditional ways (plating and etching)

Relay Dissection

  • Had a relay stick closed during some “experimenting”
  • Cut off the top to find out what happened

Fixing circuit boards
