Description
Technical field
The utility model is related to static suppressor part, more particularly to a kind of lamination sheet type polymeric electrostatic suppressor.
Background technology
In recent years, with the development of miniaturization of electronic products and multifunction, surface mounting technology is used widely, with
Sensitivity continuous enhancing, circuit chips seem more and more fragile under electric pulse impact.Protection circuit in chip by
In being limited by chip space, it is impossible to be made very big, only can guarantee that chip and circuit board are not damaged by ESD in the fabrication process
Evil, therefore, it is necessary to install ESD suppressors for chip.And traditional suppressor is due to oversized, pressure sensitive voltage is too high, rings
Answer the shortcomings of speed is slow, and energy capability is little, it is impossible to meet the demand of novel electronic product ESD protections, current lamination sheet type
Resistor suppressor starts gradually to substitute circular piezoresistor, needs a kind of volume less certainly, energy capability and logical
The higher suppressor of stream ability.
Utility model content
The purpose of this utility model is, to overcome the shortcomings of prior art, to design a kind of lamination sheet type polymeric electrostatic suppression
Device processed.
A kind of lamination sheet type polymeric electrostatic suppressor, it is characterised in that：Suppress body, the length of affiliated body including electrostatic
The direction of degree and width is both provided with least two pairs of electrodes, and the electrode layer of the electrode is described in alternate superposition Rotating fields
Electrode layer includes inner and outer electrodes, and at least two pairs external electrodes are arranged along the both sides in body length direction, each pair external electrode edge
The width of body is separately positioned on the two ends of body, wherein, the external electrode of side of the body is arranged on by superposition
Interior electrode inside Rotating fields is connected with the external electrode of the body other end；The superposition Rotating fields of the electrode are by polymeric layer
Replace with metal inner electrode layer and be formed by stacking, adjacent inner electrode layer constitutes an individual layer electrostatic and suppresses with folded polymeric layer
Device.
Preferably, described polymeric layer is ZnO ceramic layers and/or composition is titanium, tungsten, the glass phase of nickel oxide.
Preferably, less than the width of external electrode, the thickness of interior electrode is 2 μm -15 μm to the width of interior electrode, the polymerization
The thickness of nitride layer is 2 μm -40 μm.
Preferably, body is cuboid.
Having the beneficial effect that using the application, by laminated type and the static suppressor of combination of polymers, can preferably carry
High response speed, voltage overshoot is little, and energy tolerance and through-current capability are higher.
