Definitions
- the invention relates to conductor track structures on an electrically non-conductive carrier material according to the preamble of claim 1 and a method for their production.
- Such methods are u. a. can be used for the production of circuit carriers from thermoplastic materials by means of an injection molding process.
- these methods have the advantage that the tool costs can be kept comparatively low.
- the number of process steps required can be reduced because the undecomposed metal chelate complex can remain in the non-irradiated areas on the surface of the circuit carrier, making it possible to produce even medium-sized quantities in a very economical manner, whereby a particularly fine resolution of the structural image can be achieved.
- the advantages mentioned are offset by the disadvantages that the thermal stability of the metal chelate complexes described is more modern with regard to the processing temperatures High-temperature plastics such as LCP are in the limit. Therefore, the method can only be used to a limited extent in this area of material, which will become even more important with the future lead-free soldering technology.
- the metal chelate complexes must be added in a comparatively high dosage in order to obtain a sufficiently dense nucleation for rapid metallization when laser activated.
- the high proportion of complexes often impairs important usage properties of the carrier material, such as elongation at break and impact resistance.
- WO 00 35 259 A2 describes a method for producing fine metallic conductor track structures on an electrically non-conductive carrier material, in which an electrically non-conductive heavy metal complex, which is built up with organic complexing agents, is applied to the carrier material or introduced into the carrier material, which Carrier material in the area of the conductor track structures to be produced is selectively exposed to UV radiation, heavy metal nuclei being released and this area being chemically reductively metallized.
- a fine structuring of the conductor tracks is possible using a simplified and safe method.
- the object of the invention is to provide circuit structures which are simple and safe to produce on circuit carriers, which contain a comparatively small proportion of nucleating additives and are also stable at soldering temperatures and also to provide a simple and safe method for producing circuit structures, whereby compounding or injection molding of modern high-temperature plastics.
- non-conductive metal compounds are formed from thermally highly stable, non-soluble inorganic oxides which are stable in aqueous acidic or alkaline metallization baths, which are higher oxides with the structure of the spinels or are simple d-metal oxides or their mixtures or mixed metal compounds which are related to the spinel structures , we achieved that these can remain unchanged on the surface of the carrier material even in non-irradiated areas.
- the inorganic oxides used are so temperature-resistant that they remain stable after exposure to the soldering temperatures, ie they do not become electrically conductive and remain stable in the baths used for the metallization.
- the inorganic oxides contain copper.
- the non-conductive carrier material contains at least one organic thermally stable metal chelate complex in addition to at least one spinel.
- the electrically non-conductive carrier material is preferably a thermoplastic or a thermosetting plastic.
- the non-conductive carrier material can contain one or more inorganic fillers, which are formed, for example, from silica and / or silica derivatives.
- thermally highly stable, non-soluble, non-conductive, highly conductive, stable in aqueous acidic or alkaline metallization baths oxides based on spinels are mixed into the carrier material, that the carrier material is processed into components or applied to components as a coating and that heavy metal nuclei are released in the region of the conductor track structures to be produced by means of electromagnetic radiation and these regions are then chemically reductively metallized ,
- oxides based on spinels are mixed into the carrier material, that the carrier material is processed into components or applied to components as a coating and that heavy metal nuclei are released in the region of the conductor track structures to be produced by means of electromagnetic radiation and these regions are then chemically reductively metallized .
- the inorganic metal compound in the form of the higher oxides based on spinels can also remain on the surface of the carrier material in the non-irradiated areas.
- the inorganic oxides used are so temperature-resistant that compounding or injection molding is also possible for modern high-temperature plastics. In addition, these remain stable even after exposure to the soldering temperatures, ie they do not become electrically conductive and remain stable in the baths used for the metallization.
- heavy metal nuclei are simultaneously released by means of the electromagnetic radiation and that removal has taken place with the formation of an adhesion-promoting surface. In this way, excellent adhesion of the deposited metallic conductor tracks can be achieved with simple means.
- the inorganic oxides contain copper.
- the non-conductive carrier material contains at least one organic, thermally stable metal chelate complex in addition to at least one inorganic oxide.
- the non-conductive carrier material is preferably a thermoplastic or a thermosetting plastic.
- the carrier material can also be made of other suitable non-conductive materials such as. B. be formed from a ceramic material.
- the nonconductive carrier material can also contain one or more inorganic fillers which are formed, for example, from silica and / or silica derivatives.
- the wavelength of the laser can preferably be 248 nm, 308 nm, 355nm, 532 nm, 1064nm or even 10600 nm.
- the invention is explained below using an exemplary embodiment: 70 parts by weight of polybutylene terephthalate, 25 parts by weight of a pyrogenic silica with a BET surface area of 90 m 2 / g and 5% of the copper-containing PK 3095 spinel from Ferro GmbH are compounded in an extruder.
- the granules are injection molded into a component, e.g. B. processed the housing of a cell phone.
- the housing is then irradiated in the area of the conductor tracks to be applied with laser radiation which is generated by a diode-pumped Nd: YAG laser with an intensity which produces a slight removal which is associated with structured nucleation.
- the housing is hung in a commercially available chemically reductive copper plating bath.
- the conductor tracks are set up here in the irradiated areas.
