What are the test methods for thermally conductive silicone pad?

Thermal conductivity is the main factor for measuring a silicone sheet, so the measurement of it is the main aspect of our test. So what are the test methods? In fact, it can be divided into two types, one is the steady-state method and the other is right or wrong. The steady-state method, these two methods can be more specific classification, these two methods have different characteristics, according to different requirements, you can make different choices.

What is the steady state test method

The steady-state test method is a relatively basic method and is also relatively accurate. Many times this test method exists as a standard. The main methods are the plate method and the guard plate method. The benefits of applying this method The corresponding results can be obtained directly, and the cost is relatively small, but because the operation is relatively simple, so many factors affect the results, which does not mean that it is not easy to get the correct answer, and with With the development of the cardinality, the accuracy of this method is becoming less and less, and the requirements for operation are relatively high, so the experimental results are often unsatisfactory, and there is no way to obtain valid data. This is also one of his willingness to be gradually replaced.

What is non-steady state method

This test method is the opposite of the former. The main method of this test method is the transient hot line method. The application of this method is a recent matter. It can be applied because there are indeed many traditional methods. The first advantage is that the measured data is relatively accurate, and the data is directly output and can be displayed on a computer. This is very advanced and saves effort. The scope of use of this method is also very wide. It is suitable for thermally conductive silicone pads. More importantly, solid and liquid substances can be measured, but the data needs to be further processed.

So to sum up today ’s test methods for thermally conductive silicone pads, there are mainly two types. When we make a choice, we can refer to the relevant test data and make a more appropriate selection based on specific data.
