MEP EP#291: Vaporized Copper Stiction

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”
• https://www.jivamaterials.com/
• 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

• Methods
• Reddit post/thread that spawned the converstation
