Definitions
- the invention relates to a method for producing a particular three-dimensional molded body, for example a MI D component, in which at least in sections a cover layer is applied to the molded body and then over its entire surface
- Plasma coating of the surface of the molding provided with the cover layer takes place by means of a plasma coating process, so that the plasma coating enters into a adherent connection with the surface of the molding in recessed from the outer layer portions of the molding. Furthermore, the invention relates to a producible by the process molding and a cover layer for use in the method.
- Shaped body in particular injection-molded circuit carrier, which is also referred to as Molded Interconnect Device or MI D component, already belongs to the prior art.
- MI D components are components in which electrical and mechanical functions are integrated into an injection-molded part.
- Essential fields of application for MID technology are automotive engineering, industrial automation, medical technology, the household appliance industry, telecommunications technology, measurement and analysis technology and aerospace.
- the advantages of the MID technology lie in both the improved Freedom of design and environmental compatibility, as well as in an economic manufacturing process.
- the substrate including the mask is coated over its entire surface. The detachment of the fully coated mask is possible only with considerable difficulty.
- DE 10 2013 100 708 B3 already relates to a method for producing a structured surface on a shaped body, for example a 3D-MID component.
- a structured surface on moldings is a non-adhesive
- Injection molded articles by single or multi-component injection molding produced in such a way that portions of the surface of the first molded body remain free and then a full-surface coating of the entire surface of the composite body by means of plasma. Subsequently, the second molded body is detached from the composite body, so that the remaining directly on the first molded body, remaining plasma coating having the desired pattern of the coating.
- the first molded article may also be an insert, such as a glass or ceramic plate, onto which the second molded article is then sprayed.
- photoresist varnish is printed over the entire surface of a substrate and then partially covered with a stencil.
- the uncovered areas of the photoresist paint are exposed by UV radiation and cured.
- a thin metallization can be applied to the cured areas, for example by sputtering. The masked by the stencil and not
- Cured areas of the photoresist paint are then removed, for example by wet chemical methods.
- a method for producing a component with conductor tracks on the surface of the component is known.
- the surface of the component is laser-structured in such a way before spraying that a non-adhesive region with a knob-like surface structure is formed.
- the coating material preferably applied by way of flame spraying does not adhere to the surface of the component in order to form the conductor tracks.
- Coating material melted, accelerated in a gas stream and thrown onto the surface of the component.
- the particles of the coating material flatten, remain adhering primarily by mechanical interlocking and build up the coating.
- the component surface is thermally relatively heavily loaded by the flame spraying.
- the present invention seeks to provide a method and a suitable cover layer for producing a component having a structured surface, with which the production of plasma-coated molded parts is substantially simplified.
- the material of the cover layer is at least partially changed in its properties before and / or during the plasma coating and / or removed, for example by means of laser radiation selectively modified so that it forms an adhesion-rejecting surface property in the subsequent plasma coating process only in the unmodified areas.
- non-stable outer layers of UV-curable coatings have proven particularly suitable.
- the coating process is carried out as a plasma coating process in a plasma generator in which an anode and a cathode are spaced apart.
- a carrier gas which is excited by means of an arc discharge between the anode and cathode.
- the powdery coating material is injected in a particle size distribution of 100 nm to 120 ⁇ , which is on by the high plasma temperature or melted.
- Pure metals, for example copper, alloys or mixtures for the formation of the structured surface can be used as the coating material.
- the plasma stream entrains the powder particles and hurls them at the component to be coated, where the powder separates as a closed layer on the surface of the component.
- the gas molecules return to a stable state after only a short time and the plasma temperature drops again after only a short distance of the plasma flow, so that the surface of the component is only slightly thermally stressed when the plasma generator distance from the plasma generator to the surface of the component is maintained ,
- the plasma coating is preferably carried out with an atmospheric pressure plasma.
- Atmospheric pressure plasma refers to a plasma in which the pressure is approximately equal to that of the surrounding atmosphere - the so-called normal pressure. In contrast to the low-pressure plasma or high-pressure plasma, no reaction vessel is required which ensures the maintenance of a pressure level different from the atmospheric pressure. If the process is to coat parts made of plastic, plasma generators are available in a power range of 0 to 1-5 kW.
- the method according to the invention permits the use of unfocussed plasma generators for carrying out the plasma coating with the widest possible plasma jet.
- Typical beam widths are between 1-50 mm.
- the cover layer can be completely removed in this area, so that the surface of the molded body is exposed, so as to produce an adhesion of the metallic components of the plasma coating or even adhesion-promoting properties on the thus exposed surface of the molded body.
- the cover layer serves as a sacrificial layer which prevents adhesion of the coating particles by degradation of the cover layer or its chemical or physical transformation.
- the plasma coating process converts the
- the energy required for the degradation of the sacrificial layer is set by the mixing ratio of the molecular constituents.
- Ingredients include, for example, the type and composition of the polymeric material of the topcoat, photoinitiators or solvents. Such constituents can also transfer the thermal energy necessary for the degradation of the sacrificial layer in the molten state to the surface or optimize the energy input by means of energy-absorbing properties. As a result, the heating of the shaped body can be reduced. In this way, particularly finely structured plasma coatings can be realized, wherein the plasma coating an electrically conductive layer,
- a conductor track in the region of the laser-structured surface is produced, which is suitable, for example, for electrical circuit carriers.
- the laser radiation could be directed through a template with the contours to be generated.
- an embodiment in which the cover layer is selectively removed by means of the laser radiation in a writing method is particularly advantageous. As a result, a flexible manufacturing and different structuring is favored.
- the coating preferably bonds adhesively to the surface of the molded article and can have, for example, an acrylate finish.
- the cover layer is applied as a coating, in particular UV-curable lacquer, whose composition comprises at least the constituents acrylates, polyurethanes and / or photoinitiators.
- the cover layer can be applied in accordance with a surface enclosing the plasma coating to be produced.
- the molded body is enveloped by the cover layer by being immersed, for example, in the initially liquid substance, thereby forming a cover layer completely enclosing the molded body after curing.
- a near-surface plane of the shaped body is removed by means of the laser radiation.
- the roughening of the surface is effected, in which there is an optimal mechanical clamping and thus to a significant improvement of
- the method is suitable for use in almost any way.
- Moldings In particularly advantageous embodiments of the molding of polymer, glass, metal, ceramic and / or wood.
- an intermediate layer which has a substantially ceramic material portion is at least partially applied to the shaped body, and then the Cover layer applied to this intermediate layer.
- Insulation of the molded body against the plasma coating ensured, so that in principle also electrically conductive substances, such as metal body can be used as a shaped body.
- electrically conductive substances such as metal body
- a thermal insulation of the molded body is achieved as compared to the heat energy acting in the plasma coating process.
- Plasma energy takes place. This degradation can be carried out both as a decomposition process of a polymeric molecular chain and as a thermal evaporation process of a low molecular weight constituent.
- the energy input reduces the volume and weight of the covering layer of the shaped body during the plasma coating
- the cover layer is applied with a layer thickness of 1 ⁇ to 500 ⁇ on the surface of the molding, wherein the layer thickness can be dimensioned differently in different areas.
- the cover layer could be retained on the surface of the molded article in the areas not exposed to the laser radiation after completion of the plasma coating process. Appropriately, the cover layer is peeled off.
- the object according to the invention is furthermore achieved with a covering layer in that the covering layer is degradable or convertible by the energy input associated with the plasma coating process, in particular releases gaseous constituents, so as to achieve adhesion to the surface of the molding due to the associated volatile properties.
- the degradation of the envelope creates a gas pressure which prevents adhesion of the coating particles.
- Such components include, for example, the type and proportion of the polymer, photoinitiator and / or solvent.
- the cover layer contains energy-absorbing constituents, in particular particles.
- powder particles can be used for this purpose, which transfer or reflect the thermal energy necessary for the degradation of the sacrificial layer in the molten state to the surface of the cover layer.
- This shows a flow chart of a method according to the invention for producing a particular three-dimensional molded body.
