Development is substantially at the starting stage, but countries in the world all have appreciated that unmanned plane huge is answered what dual-use field had
With potentiality and broad prospect of application, unmanned plane industry development is given and payes attention to and vigorously supports extensively.
It needs that flight main control chip is installed on the mainboard of unmanned plane, in order to protect and fixed chip, chip portion is needed
It is embedded in pcb board, therefore opens the deep stepped groove of control in PCB domestic demand.It, must be to control for the service life for guaranteeing flight safety and unmanned plane
The size and depth of deep trouth have strict demand, and generally pcb board is placed on bottom plate in the prior art, in such a way that control is deep pair
Pcb board is slotted, but gong trigger has multiple main shafts, unavoidably has difference of height between each main shaft, in addition backplate surface can
Energy out-of-flatness, can all cause the tolerance for controlling deep precision excessive, to influence the quality of PCB.
Utility model content
In order to solve the relative height differential of each main shaft of gong trigger in the prior art, the public affairs of pcb board control depth precision are caused
The big problem of difference now provides a kind of structure for improving pcb board control depth precision.
Preferably, a kind of structure improving pcb board control depth precision, including the gong trigger on gong trigger platform, gong trigger platform, with
And pcb board, bottom plate is provided on gong trigger platform, bottom plate is equipped with groove, and the pcb board is arranged on groove, and described is recessed
Slot is that the mode of gong trigger controlled depth milling is formed, and the bottom surface of the groove is flat configuration.
Preferably, backing plate is provided between the bottom plate and gong trigger platform.
Preferably, the groove length and the big 10mm or more of width length and width more corresponding than pcb board.
Preferably, the depth of groove is 0.5 ~ 1mm.
Preferably, the bottom plate is resin plate or phenolic board.
Preferably, the base plate thickness is 1.7mm-2.3mm.
Preferably, at least one side of pcb board is enclosed with adhesive tape.
Preferably, the adhesive tape is wrinkle adhesive tape.
Preferably, the gong trigger is optics gong trigger.
The utility model carries out controlled depth milling to bottom plate and forms groove, the bottom surface of groove is smooth, at this time before pcb board control depth
Relative altitude between each main shaft of gong trigger is substantially zeroed, in the process of subsequent pcb board control deep processing, avoids because of gong plate
Difference in height between each main shaft of machine causes the accuracy tolerance of pcb board control depth big, controls deep tolerance by conventional positive and negative 0.15mm,
Positive and negative 0.075mm can be reached now, significantly reduce the tolerance for controlling deep precision, the quality of pcb board and product can be protected
Barrier；The bottom surface of bottom plate upper groove is flat configuration, can to avoid the out-of-flatness because of backplate surface caused by subsequent PCB to control deep precision small
The problem of, production efficiency will not be influenced by carrying out controlled depth milling formation groove to bottom plate；It is deep that the utility model can be improved pcb board control
Precision, this pcb board applies on the products such as unmanned plane, and the quality of product is good, long service life, enhance enterprise competitiveness,
Improve profit.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic top plan view of the utility model bottom plate.
Specific embodiment
The utility model is further elaborated with reference to the accompanying drawings and examples.
With reference to attached Fig. 1 and 2, a kind of structure improving pcb board control depth precision, including the gong on gong trigger 1, gong trigger platform 1
Trigger and pcb board 4 are provided with bottom plate 3 on gong trigger platform 1, and bottom plate 3 is equipped with groove 31, and pcb board 4 is arranged in groove 31
On, groove 31 is that the mode of gong trigger controlled depth milling is formed, and the bottom surface of groove 31 is flat configuration.
Backing plate 2 is provided between bottom plate 3 and gong trigger platform 1, the setting of backing plate 2 can protect gong trigger platform 1, gong trigger platform
1 price is relatively high, and damage when backing plate 2 can reduce the work of gong trigger to gong trigger platform reduces production cost.
The length and width of groove 31 is 10mm or more bigger than the corresponding length and width of pcb board 4, facilitates pcb board 4 to be put into recessed
Pcb board 4 is taken out in slot 31 or out of groove 31；The depth of groove 31 is 0.5 ~ 1mm, it can be ensured that PCB is partially placed into groove
In 31.
Bottom plate 3 is that perhaps phenolic board resin plate or phenolic board have toughness outstanding and high impact strength to resin plate,
Resistance to deformation, can any moulding the characteristics of, groove 31 that bottom plate 3 is formed by controlled depth milling will not because bottom plate 3 deformation caused by
The bottom surface out-of-flatness of groove 31.In addition, gong trigger can carry out controlled depth milling to bottom plate 3 using new milling cutter in order to improve precision,
Bottom plate 3 with a thickness of 1.7 ~ 2.3mm, 2mm can be used in the thickness of bottom plate 3.
The side bigger for 4 warpage of pcb board can be tamping by way of wrapping up adhesive tape, be avoided to after pcb board
Continuous processing causes error to influence, and adhesive tape uses wrinkle adhesive tape, and wrinkle glue is easily peeled off with having Rapid pasting, easy to tear etc.
Characteristic, viscosity is good, patch renaturation is good, temperature tolerance is good, there is the advantages of good anti-solvent penetration performance, good stability.Gong trigger
Machining accuracy for optics gong trigger, optics gong trigger is high.
The utility model carries out controlled depth milling to bottom plate 3 and forms groove 31 before pcb board control depth, and the bottom surface of groove 31 is smooth,
Relative altitude at this time between each main shaft of gong trigger is substantially zeroed, subsequent pcb board 4 control deep processing process in, avoid because
For the difference in height between each main shaft of gong trigger, causing pcb board 4 to control, deep accuracy tolerance is big, controls deep tolerance by the positive and negative of routine
0.15mm can reach positive and negative 0.075mm now, significantly reduce the tolerance for controlling deep precision, and the quality of pcb board and product can
It is protected；The bottom surface of 3 upper groove 31 of bottom plate is flat configuration, can to avoid the out-of-flatness because of 3 surface of bottom plate caused by subsequent PCB
The small problem of deep precision is controlled, production efficiency will not be influenced by carrying out controlled depth milling formation groove to bottom plate 3；The utility model can mention
The precision of high pcb board control depth, this pcb board are applied on the products such as unmanned plane, and the quality of product is good, long service life, enhancing
Enterprise competitiveness improves profit.
Above-described embodiment is only the wherein specific implementation of the utility model, and the description thereof is more specific and detailed, but simultaneously
Therefore it cannot be interpreted as that a limitation on the scope of the patent of the present invention.It should be pointed out that for the ordinary skill of this field
For personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are apparent
Alternative forms belong to the protection scope of the utility model.
