High Temperature Applications

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.

High temp electronic components in oil and gas production

Spectrum Control has a strong heritage of providing high temperature electronics to the oil and gas industry. Our specialized techniques of bare semiconductor die on thick film ceramic interconnect overcome the high temperature performance and reliability limitations of traditional glass fiber 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.
