Embodiment 1
[0038] The method for improving the mechanical properties of liquid crystal polymer products, the specific steps are:
[0039] 1) Add protective films on the upper and lower sides of the liquid crystal polymer film - thermosetting polyimide film (see figure 1 ), the area of the thermosetting polyimide film is greater than the area of the liquid crystal polymer film, and the edge of the thermosetting polyimide film is applied with a tiny weight;
[0040] 2) Put the liquid crystal polymer film covered with a protective film into a vacuum drying oven for heat treatment under a nitrogen atmosphere. Before heating up, vacuumize the vacuum oven, inject nitrogen, vacuumize, and inject nitrogen, repeat 5 times , until the residual air in the vacuum drying oven is replaced by a nitrogen atmosphere, and the oven is completely filled with a nitrogen atmosphere; then start to heat up for heat treatment (see figure 2 ), the heat treatment temperature is 250°C, and the time is 6h;
