Abstract

The invention discloses a two-piece type frame assembly of a TVS diode and a processing method. The invention relates to the technical field of semiconductor devices, in particular to a two-piece typeframe of the TVS diode. The two-piece type frame assembly comprises an upper frame assembly and a lower frame assembly, wherein the lower frame assembly comprises a lower-frame upper edge, a lower-frame lower edge and a plurality of lower-frame ribs connected between the lower-frame upper edge and the lower-frame lower edge, and a plurality of lower-frame units are evenly distributed on the two sides of the lower-frame rib; the upper frame assembly comprises an upper-frame upper edge, an upper-frame lower edge and an upper-frame rib connected to the upper-frame upper edge and the upper-framelower edge; a plurality of upper-frame units are uniformly distributed on the two sides of the upper-frame rib; and when the upper frame assembly is superposed on the lower frame assembly, the lower-frame units and the upper-frame units are aligned one by one. According to the invention, the influence of stress on the TVS diode is reduced, the stability of the TVS diode in later use is improved, and the service life of the TVS diode is prolonged.

Description

technical field [0001] The invention relates to the technical field of semiconductor devices, in particular to a two-piece frame of a TVS diode. Background technique [0002] TVS diode, also known as transient suppression diode, is a new type of high-efficiency circuit protection device commonly used. It has extremely fast response time (sub-nanosecond level) and relatively high surge absorption capacity. When its two ends are subjected to instantaneous high-energy impact, TVS can change the impedance value between the two ends from high impedance to low impedance at a very high speed, so as to absorb an instantaneous large current and clamp the voltage at both ends A predetermined value, so as to protect the subsequent circuit components from the impact of transient high-voltage spikes. [0003] As a protective device in the circuit, the quality of TVS diodes is particularly important. At present, during the production process of TVS diodes, the stress generated in the pr...
