Cryogenic Treatment of Electronics

Electronics Circuit Board

When dealing with electronics, audio equipment, and musical instruments, cryogenic processing has significant benefits. Treated materials show better conductivity and resonance. Because the cryogenic treatment of electronics, audio cables, and components affects the crystalline structure of the metal used to carry the electrical current, the parts are optimized for better performance.  

How it Works

Cryogenic Treatment of audio cables and electronics works by decreasing the thin gaps within the metal components.  This lowers the amount of artifacts in the electrical current, sometimes referred to as noise. Studies have shown that, by lowering the noise, a truer signal is received leading to better overall performance and durability of Audio equipment.

Cryogenic treatment is known to have a number of beneficial effects on electrics including:

  • Extending the life of circuit boards in military applications
  • Reducing residual stress between the layers of thin film magnetic memory wafers
  • Decreasing hysteresis in transformers
  • Increasing contact life on relays, circuit breakers, and switches
  • Increasing the Schottky contact barrier height
  • Reducing device reverse leakage current

Cryogenically-treated electrical contacts

The… life of electrical contacts is extended by a cryogenic treatment. An electrical contact is exposed to a low temperature, such as below -150F for a selected period of time. The low temperature may be obtained via a controlled rate of cooling. After the contact has been exposed to the low temperature, the contact may be returned to ambient temperature at a controlled rate. The cryogenic treatment results in extended useful life of contacts made of materials such as copper and of composite contacts incorporating silver, refractory metals, and metal oxides such as cadmium oxide and tin oxide.
