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
