Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature thermal hardness testing of epoxy molding compounds, and particularly relates to a thermal hardness testing bracket. Background Art

[0002] High-temperature hardness (hereinafter commonly referred to as thermal hardness) is an index for measuring the strength of epoxy molding compounds at high temperatures after a certain curing time. When encapsulating electronic components with epoxy molding compounds, during the encapsulation process, if the thermal hardness is too low, the thermal strength of the epoxy molding compounds will be low, and during the mold opening to remove the encapsulated product, phenomena such as runner breakage and sticking to the mold will occur, resulting in non-continuous molding. Therefore, in the formulation design and production process of epoxy molding compounds, it is necessary to control the index of thermal hardness to meet the continuous molding requirements of customers;

[0003] Existing molds use round-die molds. One set of molds can produce two sample blocks simultaneously. After manually testing the first piece, the second sample block is tested quickly.

[0004] The thermal hardness of epoxy molding compounds needs to be quickly tested after opening the mold at a certain temperature and curing time. The existing method is to manually test the first sample block and then immediately shift to test the second piece. In fact, there is a time interval of about 5 seconds between the two tests, and the second sample has cooled down, resulting in different test data and large data fluctuations. Therefore, a thermal hardness testing bracket is provided. Content of the Utility Model
