“…The SiP was sealed to prevent contaminants and moisture from entering and causing corrosion. Filling the SiP with nitrogen also protected the bare core to some extent (Sivaswamy et al , 2008). The chips were tiled onto the substrate side-by-side.…”

“…The low thermal resistance of the system allows the internal electronic components to dissipate heat rapidly. With this technology, the temperature level of existing chips can be increased (Liu et al , 2011; Sivaswamy et al , 2008; Sham et al , 2006; Yu et al , 2012). In an SiP system, an entire circuit system is packaged in one device with a low thermal resistance to allow the circuit to continue operating at high temperatures.…”

Purpose This paper aims to study a high-temperature (up to 200 °C) data acquisition and processing circuit for logging. Design/methodology/approach With the decrease in thermal resistance by system-in package technology and exquisite power consumption distribution design, the circuit worked well at high temperatures environment from both theoretical analysis and real experiments evaluation. Findings In thermal simulation, considering on board chips’ power consumption as additional heat source, the highest temperature point reached by all the chips in the circuit is only 211 °C at work temperature of 200 °C. In addition, the proposed circuit was validated by long time high-temperature experiments. The circuit showed good dynamic performance during a 4-h test in a 200-°C oven, and maintained a signal-to-noise ratio of 92.54 dB, a signal-to-noise and distortion ratio of 91.81 dB, a total harmonic distortion of −99.89 dB and a spurious free dynamic range of 100.28 dB. Originality/value The proposed circuit and methodology showed great potential for application in deep-well logging systems and other high-temperature situations.
