Abstract

The application provides a thick film circuit module for well logging and a manufacturing method thereof. The manufacturing method comprises the following steps: providing an upper tube shell with a phase change cavity and a lower tube shell with a vacuum cavity, wherein a bare chip is arranged in the vacuum cavity; performing vacuumizing treatment on the vacuum cavity in a vacuum environment; after the upper tube shell is heated to a set temperature, pouring liquid phase change material into the phase change cavity of the upper tube shell; and sealingly connecting the upper tube shell and the lower tube shell after the upper tube shell is cooled completely. The application improves the temperature resistance of the well logging instrument.
