Description

Technical Field

[0001] This utility model relates to the field of flash testing technology, specifically to an epoxy molding compound flash testing mold. Background Technology

[0002] When epoxy molding compounds are used to encapsulate electronic components, they are injected into the mold cavity under certain pressure and temperature. During the encapsulation process, some of the flash overflows through the mold gaps onto the electronic component pins and the mold, affecting the quality of the electronic component and the encapsulation efficiency. Therefore, the formulation design and production process of epoxy molding compounds need to control the flash content to meet customer requirements. National standards require flash to be tested at 175℃. The flash mold is placed on a press, and after the press closes the mold, the upper and lower mold plates are heated to 175℃ before the sample is added for testing. The flash data was measured using a digital caliper. However, when the upper and lower die panels of the press showed a temperature of 175℃, the actual temperature of the flash mold was less than 175℃, making it impossible to accurately measure the actual flash data. When measuring overflow with calipers, the measuring jaws need to be aligned with the longest overflow piece. The overflow piece is thin, and it is easily damaged when the measuring jaws are gently pushed to align with the overflow piece during the measurement process, affecting the accurate data. In addition, the steel material of the measuring jaws is relatively hard and can easily scratch the mold, increasing the mold cost. Moreover, manual measurement is slow and affects the testing efficiency. Therefore, an epoxy molding compound flash testing mold is provided. Utility Model Content

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0017] Example: Please refer to Figure 1-3This utility model provides a technical solution: an epoxy molding compound flash testing mold, including a lower mold 1 and an upper mold 2. The lower mold 1 has a product groove 101. A plurality of scales 102 for measuring the actual data of flash are provided on one side of the top of the product groove 101. The flash data can be quickly measured using the scales 102. The side of the lower mold 1 has a hole for installing a temperature sensor 104. The temperature sensor 104 is electrically connected to a display screen 105 through a controller. The actual temperature of the flash mold can be observed in real time using the temperature sensor 104. The display screen 105 is used to display the temperature of the entire mold for easy viewing by the staff.

[0018] Both ends of the lower mold 1 are equipped with lower mold handles 103, and a positioning post 106 is provided at the top corner of the lower mold 1.
