Abstract
The invention discloses a method for electroplating plastic with an electromagnetic anti-radiation layer. A plastic product is installed on an evaporation plating device; an evaporation material is put in the evaporation plating device; vacuumization is performed to 6*10<-3> Pa; Ar gas is introduced to 1*10<-1> Pa; continuous radio-frequency discharge is performed so as to ionize all the Ar gas in an ionic state; the evaporation material starts to be powered on, meanwhile the Ar gas is introduced continuously, and continuous radio-frequency discharge is performed; the vacuum degree is maintained at 4*10<-2> Pa; a Cu material is evaporated, and after a 1-minute interval, an IS material is evaporated; and the atmosphere is introduced, so that the whole evaporating process is finished. By the adoption of the method, the deep product can be well machined; the evaporation plating device low in price is used for finishing the product with the performance equivalent to that of sputtering; and a standardized electroplating process is adopted, operation is facilitated, and cost is saved.
Description
Technical field
The invention belongs to application and technical field of vacuum plating, relate to a kind of method of electroplating electromagnetism radiation protective layer, be specifically related to a kind of method of electroplating electromagnetism radiation protective layer on plastic cement.
Background technology
If need the effect reaching inside and outside shielding in product design process, chemical plating, direct spraying electric conduction paint, evaporation coating, sputter can be taked, utilize the direct injection moulding of the conductivity of carbon fiber, electro-conductive material, directly use the multiple methods such as metal shell.But the aspects such as synthesized environmental protection, the mode that wherein most important index electroconductibility is best mainly contains 3 kinds: directly use metal shell, evaporation plating and sputter.
Direct use metal shell, cost is higher, especially complicated for shape matching and have the product of more void column, is difficult to reach.Compare from all kinds of cost performance, sputter and evaporation plating are reasonable selections.
Sputter coating (sputter): in vacuum chamber, discharges to Ar gas (argon gas), forms Ar
+, then plated film target end is arranged to negative pole, product is placed in positive pole.Ar
+with the target on high speed bombardment positive pole, the atom bombardment of metal targets is departed from, directive product surface, constantly repeatedly, complete the sputter of product surface, if there is multiple target electrode, can sputter multiple material.But sputter, owing to belonging to bombardment deposition, has certain restriction for the degree of depth, if need to reach very high shielding effect simultaneously, its sputtering time can be long.
Vacuum steams (evaporation plating): in vacuum chamber, be positioned over by evaporating materials in heating material, simultaneously by electrified regulation heater strip, evaporated metal, deposits.Although evaporation plating technology and equipment is simple, effect is worse than sputter.
Summary of the invention
In view of this, the object of the invention is to the equipment utilizing evaporation plating, use for reference the principle of sputter, provide a kind of performance to be better than sputter, cost plates the suitable method of electroplating electromagnetism radiation protective layer on plastic cement with evaporation.
For achieving the above object, the invention provides following technical scheme:
Method of electroplating electromagnetism radiation protective layer on plastic cement of the present invention, comprises the steps:
Plastic cement products is installed on evaporation coating apparatus, drops into evaporating materials, be evacuated to 6 × 10
-3pa, logical Ar gas to 1 × 10
-1pa, continues radio frequency discharge and Ar gas is all ionized into ionic condition, start the evaporating materials that is energized, continue to pass into Ar gas simultaneously, and continue radio frequency discharge, keeps vacuum tightness 4 × 10
-2pa, evaporation Cu material, 1 minute, interval, evaporation IS material, logical air, completes and wholely steams process.
Preferably, 1000W radio frequency discharge 3 minutes, is all ionized into ionic condition by Ar gas.
Preferably, add 160V voltage, continue 140s and evaporate Cu material.
Preferably, add 80V voltage, continue 60s and evaporate IS material.
Preferably, surface of plastic product to be processed is carried out further coarse process to be placed in evaporation coating apparatus.
Method of electroplating electromagnetism radiation protective layer on plastic cement of the present invention, because RF discharge sustain has been evaporated to material, in whole metal evaporation stage, the sidewall being beneficial to darker product also can be electroplated preferably and obtain good effect, can ensure degree of depth 5cm completely, the resistance between sidewall 1cm 2 is within 0.5 ohm.The method can well the darker product of working depth; The relatively low evaporation coating apparatus of price is used to complete the performance product suitable with sputter; Standardized electroplating technology, is beneficial to operation, cost-saving.
