我经常从客户那里听到的一个问题是： "从冰箱里拿出来后，我需要等多久才能让焊膏和/或助焊剂达到室温才能使用？
It is indeed very important for solder pastes and fluxes to be at ambient temperature (approximately 23oC) in order for them to exhibit optimal performance, as the rheology of these materials will differ in a refrigerated state. Additionally, "cool" materials condense atmospheric moisture onto their surfaces (like a glass of cold water in the humid summer air). This condensed moisture is an unwanted ingredient in high quality soldering.
In order to quantify the amount of time necessary for these materials to reach room temperature, we refrigerated both solder paste and flux in 6oz cartridges. We then recorded the time it took to reach room temperature by placing thermocouple leads in the center of the materials through small holes that were drilled in the containers.
下图是加热浆料和助焊剂的时间与温度关系图：
For the testing above, the ambient temperature was approximately 22-24oC. The flux required approximately 2.5 hours to reach room temperature, whereas the solder paste required approximately 2 hours. It would be expected that the solder paste would reach room temperature faster than flux alone, as the metal content of the paste increases the thermal conductivity of the material.
当然，您的具体情况（冰箱温度、容器大小和形状、环境温度等）会有所不同。
