Abstract
The utility model discloses a clamping apparatus used for laminating a filter baseplate of a microstrip antenna. The baseplate comprises a core plate, an upper circuit board and a lower circuit board; the core plate is provided with a hollow groove; the upper and the lower circuit boards are covered on the upper surface and the lower surface of the core plate; the clamping apparatus comprises a pressure plate component and a padding plate component; the pressure plate component is pressed on the upper circuit board; the padding plate component is padded below the lower circuit board; and an empty groove is formed on the pressure plate component in a position corresponding to the hollow groove of the core plate. As the empty groove is formed on the pressure plate component in the position corresponding to the hollow groove of the core plate, when the core plate, the upper circuit board and the lower circuit board are laminated, the upper circuit board corresponding to the hollow groove of the core plate is free from pressure due to correspondence to the empty groove, and the upper circuit board cannot exert pressure on the hollow groove. Therefore, the utility model avoids groove surface sinking caused when pressure is exerted on the hollow groove, and ensures that signal can be transmitted in the hollow groove stably and reliably.
Description
Technical field
The utility model relates to circuit board manufacturing technology field, more particularly, relates to a kind of anchor clamps that are used for pressing micro-strip antenna filter substrate.
Background technology
Micro-strip antenna filter has advantages such as miniaturization, easy of integration, good directionality, so it has a extensive future, and especially obtains positive popularization and application on radio communication.
At present, the substrate that is used for micro-strip antenna filter adopts central layer with built-in cavity groove and the outer circuit plate pressing that is covered in the upper and lower surface of central layer to form, and this built-in cavity groove can effectively be carried out the transmission of high-frequency signal transmission and high-speed logic signal.Though the substrate inner core plates structure of micro-strip antenna filter makes improvements, but be used for the central layer after this improvement of pressing and the anchor clamps of outer circuit plate in the prior art and but do not do any improvement, this clamp structure comprises the laminate of the unlike material of multilayer build-up, because the outer circuit plate of the central layer upper surface of micro-strip antenna filter is generally the lower PTFE of hardness (polytetrafluoroethylene) layer, during pressing, anchor clamps laminate applied pressure can make the PTFE course lower recess relative with cavity groove, thereby make the groove face of cavity groove also to lower recess, influence the propagation of high-frequency signal.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of anchor clamps that pressing has the micro-strip antenna filter substrate of built-in cavity groove that are used for.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of anchor clamps that are used for pressing micro-strip antenna filter substrate are provided, described substrate comprises the central layer that is provided with hollow groove and is covered in the last circuit board and the following circuit board of central layer upper surface and lower surface, described anchor clamps comprise pressing to be located at the Anchor plate kit on the circuit board and to fill up backing plate assembly below described circuit board down, is provided with a dead slot on the described Anchor plate kit and with the hollow groove corresponding position of described central layer.
Further, described Anchor plate kit comprises the folded laminate of establishing of multilayer, described dead slot be located at orlop and with the laminate of described baseplate-laminating on.
Particularly, the laminate of described Anchor plate kit is followed successively by backing plate, steel plate, brown paper and supporting plate from the bottom to top.
Further, described backing plate assembly comprises the folded laminate of establishing of multilayer.
Further, the laminate of described backing plate assembly is followed successively by supporting plate, brown paper and steel plate from the bottom to top.
The anchor clamps that the utility model provides, on Anchor plate kit and with the hollow groove corresponding position of described central layer, one dead slot is set, when central layer and last circuit board, down during the circuit board pressing, the last circuit board corresponding with the hollow groove of central layer is because and the effect that be not stressed corresponding with dead slot, circuit board also can not exerted pressure to hollow groove in the event, avoid the hollow groove effect of being stressed and produced the defective that groove face caves in, and then guaranteed stable in hollow groove, the propagation reliably of signal.
Description of drawings
Fig. 1 be the utility model provide the anchor clamps pressing time schematic diagram.
Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Please refer to Fig. 1, the micro-strip antenna filter substrate comprises the central layer 1 that is provided with hollow groove 11 and is covered in the last circuit board 2 and the following circuit board 3 of central layer 1 upper surface and lower surface in the present embodiment, the described anchor clamps that are used for pressing micro-strip antenna filter substrate comprise pressing to be located at the Anchor plate kit 4 on the circuit board 2 and to fill up in the backing plate assembly 5 of described time circuit board 3 belows, is provided with a dead slot 6 on the described Anchor plate kit 4 and with hollow groove 11 corresponding positions of described central layer 1.Described Anchor plate kit 4 comprises the folded laminate of establishing of multilayer, described dead slot 6 be located at orlop and with the laminate of described baseplate-laminating on.In the present embodiment, the laminate of described Anchor plate kit 4 is followed successively by backing plate 41, steel plate 42, brown paper 43 and supporting plate 44 from the bottom to top.Described dead slot 6 is located on the backing plate 41 and the position corresponding with hollow groove 11.Described backing plate assembly 5 also comprises the folded laminate of establishing of multilayer.In the present embodiment, the laminate of described backing plate assembly 5 adopts supporting plate 44, brown paper 43 and the steel plate 42 identical with Anchor plate kit, and described supporting plate 44, brown paper 43 and steel plate 42 stack from the bottom to top.
In the present embodiment, the last circuit board 2 that is covered in central layer 1 upper surface is generally PTFE (polytetrafluoroethylene) layer, and PTFE has good microwave radio electric property, also is the lower material of a kind of hardness simultaneously.The following circuit board 3 that is covered in central layer 1 lower surface is generally the material layer of the FR-4 grade with high frequency performance.When circuit board 3 is by the anchor clamps pressing under last circuit board 2, central layer 1 reach, the last circuit board 2 corresponding with the hollow groove 11 of central layer 1 is because and effect that be not stressed corresponding with dead slot 6, circuit board 2 also can not exerted pressure to hollow groove 11 in the event, avoid hollow groove 22 effect of being stressed and produced the defective that groove face caves in, and then guaranteed stable in hollow groove 11, the propagation reliably of signal.
