Optimization of a Ceramic Circuit Board Clamp
Keywords: ceramic circuit boards, wireline, geothermal well logging
This paper documents the design optimization of a clamp for securing a ceramic circuit board to the electronics chassis in a wireline tool for operation up to 300°C+. This clamp fixes the extreme lower end of the ceramic circuit board to a common aluminum chassis while allowing the board and chassis to undergo differential thermal expansion. After developing equations that describe the stress, deflection, and thermal expansion of the clamp/board assembly, this report discusses the use of these equations to select the geometry and material options available in the design.
