Definitions
- the invention relates to a method for producing an electrically conductive structure, in particular a conductor track, on a non-conductive carrier material which contains an additive with at least one metal compound, wherein the carrier material partially
- MID Molded Interconnect Devices
- MID technology combines electrical and mechanical functions in one component.
- the conductive structure is integrated into the housing and thus substitutes the conventional circuit board to reduce weight, space and installation costs.
- LDS laser direct structuring
- carrier materials are injection-molded in one-component injection molding with specially additized plastic granules as molded parts.
- the additives can be reacted in a spatially selective manner in a physico-chemical reaction to catalytically active nuclei, which in a subsequent chemical
- Metallizing bath selectively deposits metal at the sites treated in this way.
- the laser has the task of creating a micro-rough surface in order to ensure adequate adhesion of the metal layer on the plastic substrate
- the LDS process allows circuit layouts to be adjusted or changed in no time at all without tool conversions. This circumstance and the commercial availability of various LDS-enabled plastics has ultimately led to the LDS process being the leading technology in MID manufacturing.
- nanoscale non-conductive metal compounds are used whose particles have nanodimensions with characteristic sizes below 200 nm. This preserves the transparency of the support material and the function of the non-conductive metal compound.
- WO 2012/056385 A1 describes a method with an improved electroless plating performance of LDS materials.
- the type of additive essentially determines which wavelength the laser radiation to use can have and how efficiently it is absorbed.
- Laser irradiation is converted into catalytically active nuclei, as it would cause the additive alone.
- the additive contains, in addition to a first region formed by, for example, inorganic metal compounds, at least a second region having a different chemical composition, and the oxidation state of the metal in the additive is reduced by the laser activation.
- a second area as substance with different chemical
- a reactive microenvironment is created for the additive and the chemical reaction with the carrier material substantially reduced or completely avoided. Since such a procedure makes the process of converting the additive into catalytically active nuclei more efficient, the
- the additive-shell hybrid provides all the necessary for the required chemical-physical reaction substances, at the same time eliminates the limitation to certain
- Plastics or plastic groups For example, this makes a carrier material suitable with a substantial proportion of material of a PTFE for carrying out the method according to the invention, when the additive provided with the second region is mixed.
- such a second region for example as a coating, in some cases not only can significantly reduce the agglomeration, but also has an advantageous effect on the subsequent chemical metallization. more accurate
- An essential advantage of the invention results in particular from the fact that the additive can be supplied to any carrier materials and therefore the desired laser activation is reliably achieved without consideration of the special properties of the carrier material. In particular, it is thus possible to dispense with the aids previously required for adaptation to different properties of the carrier material.
- the additive can also be supplied or admixed only in the shaping process, so that the additive does not have to be present in the carrier material before processing.
- the second range also leads to significantly improved mechanical properties when it contains substantially organic compounds.
- the second region at the interface between the second region and the carrier material, in each case essentially organic components meet one another.
- the second region leads to far less disturbances in the structure of the plastic than the carrier material of the additive.
- the second region may preferably be applied to the additive as a coating over its full area so as to achieve a separation of the additive from the carrier material.
- the coating thickness is selected so that it has a sufficient adhesive strength to the additive and so in particular when mixing the additive provided with the coating in the carrier material is not separated from the additive or the
- the coating with an amount corresponding to the stoichiometric ratio between at least one in the Coating contained active ingredient and the additive applied to the additive, so that the amount of substance required for the reduction of the additive in the coating is available. As a result, an interaction or a chemical reaction of the additive with the carrier material is largely prevented.
- the invention is a
- the additive could be in an aqueous solution which is in liquid form in the
- Carrier material is introduced. Particularly promising, however, is one
- Embodiment of the invention in which the additive provided with the second region in a strewable or free-flowing form, in particular powdered, prepared and in the
- Carrier material is mixed. This simplifies the manufacturing process as well as the system requirements for making the mixture. In particular, the desired mixture can be monitored in a simple manner on the basis of the mass ratios.
- Another embodiment of the invention which is also particularly promising, is achieved by introducing an absorber in the second region, which converts the laser energy for laser activation into that contained in the additive
- Laser radiation introduced energy into the required activation energy, which is used to trigger the reaction between those in the second area on the one hand and the
- additive particles contained on the other hand required reactants is implemented in an optimal manner and thus increases the efficiency.
- These substances acting as absorbers in the second region therefore also allow the desired activation in a particularly advantageous manner if the second region or the additive is transparent to the wavelength of the laser radiation. According to the invention, it is thus also possible to use those additives which can not be activated per se with the selected laser, by the reaction being effected by corresponding reaction partners in the second region and the resulting interaction of those contained in the second region
- the additive is largely decoupled from the selection of the laser.
- the absorber is on the wavelength tuned by the laser. For example, absorbers in the IR wavelength range are suitable for this purpose.
- the carrier material contains as a substantial proportion of material a semiconductor material, ceramic and / or glass, so that the inventive method for selective activation and subsequent metallization can also be carried out in conjunction with such carrier materials, which themselves are not chemically reducing to the Can act additive. Furthermore, the chemical reaction of the additive with its second region substantially reduces a change in the chemical or physical properties of the carrier material.
- a portion of copper (II) oxide powder (Sigma-Aldrich) is dried in a vacuum oven at 150 ° C and in a twin-screw extruder (Collin) with a part
- Polybutylene terephthalate (Lanxess) processed into a homogeneous granules.
- the granules are first in a fine impact mill (Hosokawa / Alpine) to a fine impact mill (Hosokawa / Alpine) to a fine impact mill (Hosokawa / Alpine) to a fine impact mill (Hosokawa / Alpine) to a fine impact mill (Hosokawa / Alpine) to a
- thermosetting copper (I) oxide-polyester hybrid is then compounded at eight percent by weight in polyethylene (LyondellBasell) and injection molded into workpieces.
- Fig. 2 shows an additive with a coating on one, a core forming, first
- FIG. 3 shows an additive with a second region forming a core.
- the additive 1 contains at least one metal compound forming a first region 2.
- this metal compound is preferably selectively activated, whereby catalytically active nuclei form in the areas thus laser-activated, which are subsequently metallized.
- the additive 1 contains, in addition to the metal compound, a second region 3 with one or more substances of a different chemical composition from the metal compound, so that the oxidation state of the metal in the additive 1 is reduced by the laser activation.
- the additive 1 has a further, matched to the metal compound substance with different chemical composition, this is a
- the process of converting the metal compound into catalytically active nuclei is thereby carried out much more efficiently, independently of the carrier material, while at the same time reducing the required amount in the carrier material.
- additive 1 also eliminates the limitation to certain plastics or plastic groups.
- an irregular mixture of the two regions 2, 3 is used for this purpose, which, above all, permits simple production, for example also during the shaping process.
- the metal connection can completely enclose the second area 3, if, for example, at certain temperatures
- the second region 3 is to support only the chemical reaction.
