The invention provides a thick film circuit module for well logging and a manufacturing method thereof, and the manufacturing method comprises the steps: providing an upper tube shell with a phase change cavity and a lower tube shell with a vacuum cavity, and enabling a bare chip to be arranged in the vacuum cavity; carrying out vacuumizing treatment on the vacuum cavity in a vacuum environment; after the upper tube shell is heated to a set temperature, the liquefied phase change material is poured into a phase change cavity of the upper tube shell; after the upper tube shell is cooled, the upper tube shell and the lower tube shell are connected in a sealed mode. The temperature resistance of the logging instrument is improved. 本发明提供了一种测井用厚膜电路模块及其制作方法，所述制作方法包括，提供具有相变腔体的上管壳以及具有真空腔体的下管壳，其中，真空腔体内设有裸芯片；在真空环境下，对真空腔体进行抽真空处理；将上管壳进行加热至设定温度后，将液化的相变材料灌注入上管壳的相变腔体中；在上管壳冷却完毕后，将上管壳与下管壳之间密封连接。本发明提高了测井仪器的耐温性能。
