Electronic manufacturing field now, radome is being widely used, and is mainly used in the fields such as mobile phone, GPS.Typically using radome is surrounded the interference source of electronic unit, circuit, sub-assembly, electric wire or the whole systems such as the element on pcb board and LCM, prevent that interfere with electromagnetic field is to outdiffusion, prevent that simultaneously they are subject to the impact of external electromagnetic field, thereby realize the purpose of anti-electromagnetic interference (EMI).The metal material processing such as material employing different-thickness unusual according to the use occasion stainless steel of existing radome, foreign copper-nickel alloy, nickel-clad steel plate are completed.Be soldered directly on pcb board with SMT during installation.
Existing radome product all adopts the metal material manufacturing, and the price of material own is very high.Moreover, owing to being metal material, so existing radome product is all the metal stamping processing of carrying out Simulation Based On Multi-step with high-precision metal stamping die on punch press, needs high accuracy and large-tonnage punch press and high-precision metal stepping punching mould to carry out the punch process of Simulation Based On Multi-step.The cost that the cost of mould and mould are safeguarded is also very high.Especially for the less product of product quantity demand, only the overhead cost of mould is just very high.And existing radome is in use, is generally that leg metal welding technique with the radome product is welded on and needs outside guard block, on pcb board, and complex procedures, assembly cost is high.
Therefore, in the urgent need to a kind of new product and technology, substitute the existing radome problems such as its cost of material is high, die cost is high to overcome, the assembling difficulty is large.
Summary of the invention
For overcoming the problem of the invention described above, the present invention has aimed to provide a kind of brand-new radome product.
At first the present invention discloses a kind of radome, is made of the supporting layer with some strength and the conductive layer that is compounded in the supporting layer outside; Described supporting layer is non-conductive, and its vicat softening temperature is not less than 100 ℃.
Radome of the present invention, wherein said supporting layer is made by makrolon material.Also can use polyester material or other plastic materials; Optimization polycarbonate material the most wherein.Preferred 0.125～the 0.5mm of the thickness of described supporting layer.
Radome of the present invention, wherein said conductive layer are aluminium foil or Copper Foil.Preferred 0.05～the 0.125mm of thickness 5 of conductive layer.
The present invention discloses the preparation method of above-mentioned radome on the other hand, comprises the steps:
1. will become laminar composite as the Material cladding of supporting layer and conductive layer;
2. cross cutting gained laminar composite, prepare radome mould material;
3. use the indentation line of cutting die to extrude crease line at supporting layer one side surface of gained radome mould material;
4. to step 3. the radome mould material that gets of machining carry out Bending Processing according to crease line, obtain the radome product.
Comparatively preferred preparation method be with the plastic sheet-like such as Merlon, polyester or weblike material as supporting layer, then with as thin metal foil belt Material claddings such as the aluminium foil of conductive layer, Copper Foils, and then complete the processing of radome product.
Preparation method as preferred and concrete radome comprises the steps:
1. will as the metal forming adhesive tape of conductive layer with compound as the plastic sheet of supporting layer, make double-deck laminar composite;
2. compound good laminar composite is carried out cross cutting processing, cut plastic cover, the consistent radome mould material of monnolithic case after obtaining profile and radome launching;
3. according to the fold requirements of preparation radome, in the part that radome mould material need to fold, use the indentation line of cutting die to extrude crease line on the surface of plastic layer, then the edge waste of product is drained;
4. with the plastic folding bender according to the crease line position to step 3. resulting radome mould material carry out Bending Processing, obtain the radome product.
In above-mentioned processing method, the metal forming adhesive tape preferred aluminium foil of procedure of processing described in 1. or the single face adhesive tape of Copper Foil, more preferably used thickness is the metal forming of 0.05～0.125mm; Plastic sheet is generally Merlon, the polyester material of sheet or web-like, also can be the plastics of other classes.But the vicat softening temperature of plastic sheet otherwise lower than to 100 ℃.And the thickness of its use is 0.125～0.5mm, to reach certain support strength.
The radome that the method processing of use the invention described above obtains in use, needn't adopt the welding connecting mode in traditional handicraft, can adopt the bonding mode of conductive glue, conductive material layer compound on the radome leg and the pad on pcb board are bonded together with conductive glue.Both can substitute the effect that structure that welding manner plays connects, again effective ground connection.
The present invention possesses following advantage:
The present invention changes the metal material that the conventional shields product uses and adds the metal stamping technique that adopts man-hour, adopts common plastics composite metallic material rubber belt material and plastics cross cutting processing technology.With common cutting die, plastic material and metal forming adhesive tape are carried out cross cutting processing, the cost of raw material is low, and processing technology is simple and easy to control, die cost and low processing cost.The product that obtains can shield electromagnetism effectively.
