High Temperature Electronics Solutions

High Reliability Electronics for Harsh & Extreme Environments

Spectrum Control has an extensive history of supplying robust, high reliability electronic products into the Space, Energy, Aerospace and Defence markets, with product capabilities satisfying Standard Temperature -55°C to 150°C and High Temperature 150°C to 175°C.

Spectrum Control has developed and qualified a comprehensive range of capabilities and processes to realise hybrid multi-chip modules (MCM’s) suitable for continuous operation at Ultra High Temperature (225°C) and under severe mechanical shock and vibration. Spectrum Control is expanding on its supply of microelectronic products and services supporting mission critical applications, including the design and manufacture of RF/microwave, power and opto-electronics for exposure to harsh environments extremes of temperature and vibration and applications where size and mass are a premium.

With over 70 years experience in the custom design, vertical integration, in-house manufacturing and testing of high reliability microelectronics, Spectrum Control encompasses a blend of harsh environment electronic design and packaging expertise not common in the industry today.

Oil & Gas, Industrial and Energy Capabilities

Spectrum Control has a strong heritage of providing proven technologies to harsh environment markets. Spectrum Control's specialist techniques of bare semiconductor die on thick film ceramic interconnect overcomes the high temperature performance and reliability limitations of traditional glass fibre laminate printed circuit boards.

Spectrum Control's high temperature technology can reduce costs and downtime by prolonging the life of expensive drilling and monitoring equipment, with features including extended lifetime at 225°C and on-going development in ultra high temperature ranges of 200+°C. We provide custom microelectronic solutions to reduce unnecessary and costly downtime due to the failure of short lifetime electronics within equipment encountering extremes. This includes Measurement While Drilling (MWD), Logging While Drilling (LWD) and wireline in intelligent completions equipment. Our product solutions are specifically designed to fit down to 1" tubes to provide an ideal solution for small diameter tools operating at depth.
