Description

Technical Field

[0001] The utility model relates to the technical field of MOS tube processing, in particular to a plastic sealing mechanism for MOS tube processing. Background Art

[0002] MOS tube, namely metal-oxide semiconductor field effect transistor, is a discrete device in semiconductor active components. It controls current by changing voltage and is a voltage-controlled device. The working principle of MOS tube mainly includes two processes: establishing a conductive channel and establishing a drain current. When the external positive gate-source voltage VGS is greater than 0, an electric field will appear in the oxide layer under the gate. This electric field will attract free electrons in the P region and make them gather under the oxide layer to form an N-type conductive channel. When the channel is established, if there is a drain drive voltage VDS, the drain current will appear.

[0003] MOS tubes need to be plastic-sealed after processing. In the field of electronics, plastic-sealing materials are mainly epoxy molding compounds, which use epoxy resin as the base resin and phenolic resin as the curing agent, plus some other fillers, such as coupling agents, flame retardants, fillers, colorants and other trace ingredients, which are converted into thermosetting materials through chemical reactions.

[0004] However, the existing MOS tube processing plastic sealing mechanism is not convenient for continuously feeding the MOS tube during the plastic sealing process, and the plastic sealing efficiency of the MOS tube is low, which reduces the production efficiency. Therefore, a MOS tube processing plastic sealing mechanism is proposed to solve the above problems. Utility Model Content
