Definitions
- the invention relates to metallizable molded parts, processes for their production and their use as a component with integrated electrically conductive sections for electrical applications.
- thermoplastic materials with integrated electrically conductive sections are known in principle.
- PA 12 in particular was used here as a non-metallizable component and polyamides based on ⁇ -caprolactam and / or hexamethylenediamine and adipic acid as a metallizable component, both components being used in most cases in the form of glass-fiber reinforced compounds.
- DE 44 16 986 describes a method for producing a special component from a plastic Kl from the group that is difficult or impossible to metallize
- the following cannot be metallized under the conditions typical for PA6, e.g. partially aromatic polyamides.
- the Durethan T40 (commercial product from Bayer AG, partially aromatic polyamide, molding compound set according to ISO 1874: PA6I, MT, 12-030), which cannot be metallized under the conditions customary for PA6, is partially galvanized by melt compounding with 30% glass fibers, so that the material is not considered as Alternative for PA 12 comes into question.
- partially aromatic polyesters such as, for example, polybutylene terephthalate (PBT) and polyamides (PA) are insoluble in one another in the melt and therefore do not show any miscibility. Due to this incompatibility, no blends of polyester (including PBT) and PA (including PA6) of commercial importance are known to date (Z. Xiaochuan et al, Polymers and Polymer Composites, Vol. 5, No. 7, 1997, S 501 - 505). Probably for this reason, PBT / PA blends are not mentioned in the plastic manual polyamide (plastic manual polyamide 3/4, Carl Hanser Verlag, 1998, ISBN 3-446-16486-3, p. 131 - 165). Therefore, it has previously been assumed that combinations of PBT and PA in two-component injection molding are unsuitable for 3-D MID applications.

- MID is generally understood to mean the following:
- MID Molded Interconnect Devices
- MID has been an internationally introduced term since the early 1990s to refer to spatially injection-molded circuit boards. The idea behind this is to produce electrical connecting elements based on thermoplastic materials in a three-dimensional, spatial arrangement. MIDs carry electricity, form shielding or transmitting surfaces, carry electronic components and integrate mechanical elements. The MID technology extends the conventional circuit board technology, which is limited to one room level, and is partly in competition with it.
- MIDs One of the most frequently used manufacturing processes for MIDs is the two-component injection molding technique followed by wet chemical metallization of a plastic component. This process enables the greatest geometrical design freedom in the manufacture of MIDs.
- a composite body is produced from two thermoplastics, one component of which can be metallized, while the other component remains completely unaffected by the chemical action of the metallization electrolytes.
- the metallizable plastic can be structured in the form of electrical conductor tracks. However, it can also be structured over a large area and thus, after metallization, contribute to the shielding of electromagnetic interference fields, specifically dissipate frictional heat or become more wear-resistant.
- the structural fineness for example the width of electronic conductor tracks, can be reduced to about 500 ⁇ m.
- Such fine conductor track structures are achieved if the metallizable plastic is injected in the first shot and the non-metallizable plastic is extrusion-coated in the second shot. But the reverse order is also possible.
- the location and number of sprues, the material costs and the adhesion between the two plastic components depend on the type of sequence.
- the adherent metallizability of plastics is a crucial point in the manufacture of MIDs.
- AHC, Kerpen, a provider of functional surface technology uses a process (Baygamid® process etc.) for adhesive metallization especially for polyamides.
- the coating is carried out by wet chemical means by immersing the workpieces in suitable electrolytes. First, an approximately 2 ⁇ m thick metallic stop layer is applied. It can be further reinforced chemically (for example with chemical nickel) or glavanically (for example with copper). Chemical and galvanic layers can also be combined with one another.
- Polyamides of types PA 6, PA 66, PA 66/6 and PA 46 and copolyamides with a glass fiber or mineral fiber filling up to 40% can be metallized.
- the adhesive strength of the applied metal layers is more than 1 N / mm.
- Individual chemically nickel-plated polyamide types pass temperature cycling tests, for example a three cycle from + 140 ° C to -40 ° C. There is no shifting of the layer.
- the manufacturing costs of a car door lock carrier using this MID technology could be reduced to almost half the costs for conventional manufacturing.
- the door lock carrier is located in the car door behind the door handle. Depending on the equipment of the vehicle, it is equipped with a lock heater, the control for the central locking and the activation of the automatic interior lighting.
- Current-carrying strands, microswitches and resistance wire have to be mounted in a conventional manner on an aluminum die-cast body.
- the support structure generated in the first shot already contains all the storage and storage facilities relevant for the later function
- the metallizable component is overmolded in the second shot and, after the metallization, replaces the current-carrying strands of conventional production.
- Another application is the production of a car sunroof control as a MID based on polyamide.
- fine conductor track structures are created, but also later plug contacts in the first shot.
- the second shot creates the non-metallizable body from another type of polyamide. It contains all mechanical components. After the metallization of the two-component polyamide, assembly is limited to assembling the electrical components and soldering them. Compared to the conventional PCB solution the number of mechanical components is reduced and the assembly effort is minimized. However, the conventional assembly technology, especially in the area of assembly and soldering, can be retained. Special advantages are:
- thermoplastic materials for the production of circuit carriers offers the almost unlimited freedom of design for the construction of electronic assemblies, as is made possible by injection molding technology.
- the miniaturized and lighter MID assemblies allow new functions and the design of any shape.
- the miniaturized MID assemblies reduce the otherwise necessary use of materials.
- the MID technology is characterized by a number of improvements in terms of its environmental compatibility. During the pretreatment of the most important MID-suitable plastics, strongly oxidizing acids are avoided. In addition to environmentally friendly production, reducing the variety of materials also plays a decisive role. This favors the recycling of basic materials and the uncritical disposal of residual materials. By using thermoplastics, many can

- the molded parts can be produced by a process in which (A) is first

Electrochemical conversion (electroplating, possibly with a multi-layer structure). All of this, as described for example in DE 43 28 883 or EP 146 723 or EP 146 724, which are hereby incorporated by reference into this document. Further descriptions of this or a similar process can be found in the literature (GD Wolf, F. Funenger, Metallized Polyamide Injection Moldings, Bayer SN 19038, May 1989; U. Tyszka, The standard, large-scale galvanic metallization of injection molded parts made of polyamide, Galvanotechnik 80, 1989, pp. 2 ff; and literature cited there).
- the metallization of plastic surfaces can be achieved by physical metallization (preferably metal vapor deposition, vacuum metallization) or chemical metallization, preferably wet-chemical electroless or wet-chemical electro-galvanic metallization (galvanization), chemical metallization in particular, in particular wet-chemical (electroless or electro-galvanic) for this invention.
- Metallization is preferred.
- organometallic activators that have been developed for use in novel metallization processes.
- organometallic activators that have been developed for use in novel metallization processes.
- These are complex compounds of noble metals, preferably palladium or platinum, with different organic ligands.
- the organic ligands were chosen so that there is a special affinity for the polyamide surface, which makes a significant contribution to the adhesive strength of the metal layer to be applied. Because of this novel activation principle, it was possible to achieve that only a very slight roughening of the polyamide surface has to be carried out as an additional measure for very good metal adhesion.
- the entire pretreatment before chemical nickel plating consists of the following stages:
- the dwell time in the baths is 5 to 10 minutes at approx. 40 ° C.
- the first metal layer can then be immediately deposited in any chemical nickel bath. After a first adherent conductive metal layer has been applied, the usual electroplating process, e.g. connect the galvanic layer structure of nickel / copper / nickel / chrome without any problems.
- the process enables the adherent metallization of different commercially available polyamides.
- the application of the method is not restricted to polyamide 6 types.
- Injection molded parts made of polyamide 66 can also be metallized without any problems while observing the optimized process parameters.
- tailor-made metallizable polyamide types are available, which are reinforced with glass fibers for the requirements for high rigidity and heat resistance or for setting a reduced tendency to warp with mineral fillers. Flame retardant products are also available in this way.
- polyamide types with special elastomer modification have been developed.
- the class of elastomer-modified, glass fiber-reinforced polyamides is particularly suitable for components that have to meet at most requirements with regard to dimensional stability, dynamic fatigue strength and heat resistance, for example when used in the motor vehicle engine compartment.
- the glass fiber reinforcement significantly reduces the thermal expansion coefficient of the injection molded parts, so that the adhesive bond between the metal surface and the plastic substrate remains guaranteed even with extreme temperature changes.
- the electroplating step preferably of the metalizable plastic K (II) comprises the following steps: G (I) disintegrating the surface by dissolving baths, preferably containing calcium salts, G (II) chemical deposition of metals, preferably palladium, to produce a conductive one

- the cheapest process for producing the molded parts is carried out using a two-component injection molding process and subsequent galvanization.
- two-component injection molding was only used to describe the process in which two materials are injected into one another. In the present case, however, it is about two plastics being sprayed onto one another. This process was previously called two-color injection molding.
- Typewriter keys, switch buttons and the like were preferably produced with it by first injection-molding a cap with a recess in the form of the character to be represented. This was then back-injected with a different colored material, whereby the recess for the sign was filled.
- Plastic used The MID's trace geometry is shown in relief. In the second shot, the areas between the conductor tracks are filled with a plastic that cannot be metallized.
- the conductor track structure can be injected as a depression from the non-metallizable component in the first shot and filled with the metallizable component in the second shot.
- the MID base part After the second shot, the MID base part has its final geometric shape, and the metallizable component is metallized in the subsequent steps.
- Two-component injection molding offers the greatest geometric freedom of all MID manufacturing processes. Difficult conductor track geometries and plated-through holes can be realized in this process. The structuring of the conductor track geometry takes place during the injection molding. The smallest trace width is 0.25 mm. It depends on the flow properties of the plastic and the
