Definitions
- the invention relates to a method for producing a composite structure from at least one conductive structure, a carrier made from a non-conductive carrier material made of plastic and at least one electronic component by means of laser radiation, wherein the non-conductive carrier material contains an additive which is subsequently applied by irradiation with the laser radiation in an electroless metallization bath forms catalytically active species.
- carrier materials are injection-molded as molded parts in one-component injection molding with plastic granulate with special additives.
- the additives can be converted into catalytically active germs in a physico-chemical reaction in a location-selective manner, with metal being deposited on the areas treated in this way in a subsequent chemical metallization bath.
- conductor track structures are described on an electrically non-conductive carrier material, which consist of metal nuclei and a metallization subsequently applied to them, the metal nuclei being created by breaking up electrically non-conductive inorganic metal compounds contained in the carrier material by electromagnetic radiation.
- DE 102014 114986 A1 describes a method for producing a conductor track structure on a circuit carrier by selective laser irradiation corresponding to the conductor track structures to be produced, which is subsequently generated in a metallization bath without external current.
- laser radiation with a wavelength of 1,064 nanometers and a pulse frequency of 100 kHz is used here.
- a thermosetting copper oxide-polyester hybrid is mixed into the carrier material and injection molded into workpieces, which are then selectively activated by laser for subsequent metallization.
- DE 102012 010635 A1 relates to a method for direct 3D structuring of hard, brittle and optical materials, in which the surface is structured with an ultrashort pulse laser and a 3D structure or shape is thereby introduced in a targeted manner.
- thermosetting plastics as carrier material, to be the foreign deposits that occur. Since thermosets do not melt but are decomposed, considerable amounts of carbon are released, which is catalytically active in an electroless plating bath.
- the invention is therefore based on the object of creating a method in which impairment of the conductive structure produced in this way on the carrier material due to removal products is substantially reduced.
- a further reduction in the structure sizes of the electrically conductive structures is to be made possible.
- a carrier made of a non-conductive carrier material made of thermosetting plastic and at least one electronic component by means of laser radiation the non-conductive carrier material containing an additive which is subsequently applied by irradiation with the laser radiation in an electroless metallization bath forms catalytically active species
- the conductive structure is formed by irradiation by means of pulsed laser radiation with a pulse duration of less than 100 picoseconds and subsequent electroless metallization and the pulse repetition rate is set in such a way that successive pulses in the area of a respective additive to be activated or an additive area overlap on the Additive or the additive area are deflected.
- the invention is thus based on the surprising finding that the method for producing an electrically conductive structure by laser activation of the metal compounds contained in the additive, in particular with ultrashort pulse lasers, in particular also with thermosets, can be used without problems and has the advantage that fewer foreign deposits occur.
- a method for direct laser structuring is created which, on the one hand, reliably achieves the energy input required for laser activation, but, on the other hand, limits the heating in such a way that not only significantly fewer removal products arise, but also the temperature of which is so low that adhesion to the carrier material is very low and these can therefore be easily removed.
- particularly fine electrically conductive structures can be produced in this way because the avoidance of foreign deposits also prevents the associated risk of short circuits. As a result, the structure width and the spacing between the structures can be reduced.
- Another particularly promising embodiment of the method according to the invention is also achieved when the number of laser pulses per second (pulse repetition rate) is dimensioned so large, for example 2 to 2.5 MHz, that successive pulses in the area of a respective additive particle to be activated or an additive area act with overlapping areas of influence. As a result, several successive pulses always act on each additive particle or each additive area, whereby the energy input is correspondingly increased.
- the thermal energy coupling into the carrier material is so low that the temperature is not sufficient to reduce the additive, for example a Cu-Cr spinel, to elemental copper, and thus the catalytically active species for the desired metallization do not arise or do not arise reliably and in particular irregular partial metallizations occur.
- the overlapping areas of action of successive pulses also ensure that the temperature during structuring is not too high, so that, in contrast to the prior art, the ablation products do not get hot and can therefore adhere to the carrier material in an undesirable manner in such a way that they do not stick can be removed more reliably.
- the method creates a composite structure in which the non-conductive carrier material contains an additive which has catalytically active species formed as a result of the action of laser radiation, the conductive structure being irradiated by means of pulsed laser radiation, in particular an ultrashort pulse laser, and by subsequent metallization in the Metallization bath is formed.
- pulsed laser radiation in particular an ultrashort pulse laser
- a quasi-athermal processing of the carrier material is achieved in that the material is evaporated directly due to the extremely high peak intensities, so that no or almost no melt is produced.
- the pulses are so short that during the pulse duration there is no transmission of the energy in lattice vibrations and thus in an increase in temperature takes place. It is assumed that the energy introduced by the ultrashort pulse corresponds to the energy required to evaporate the material, so that no further energy is available for thermalization.
- the invention is based on the surprising finding, that not the thermal energy input, but the maximum intensity forms the basis and thus creates the cause and necessary prerequisite for the activation of the metal compounds.
- the non-conductive carrier material contains at least one inorganic filler with a maximum particle size of 50 ⁇ m.
- filler materials can also be used that are not destroyed or split by the acting laser radiation because, due to their small particle size, they do not impair or hinder subsequent machining processes, for example the introduction of recesses such as bores including through bores or blind holes.
- the fillers can thus be selected without restriction according to the desired technical properties of the thermoset, for example with regard to viscosity, CTE (coefficient of thermal expansion) or the solidification time.
- the adhering, catalytically active ablation products in the area of bores as so-called “collar formation”, which are particularly disadvantageous in the prior art, are reliably avoided.
- this does not increase the cycle time.
- ultrashort pulse lasers from a picosecond laser source considerably less heat is generated during the ablation. This prevents the generation of hot ablation products during drilling and the formation of collars even at higher powers.
- the use of higher capacities leads to higher removal rates, whereby the cycle time can even be reduced in practice.
- the change from nanosecond to picosecond pulses with otherwise constant parameters when structuring the carrier material and the associated reduced heat input, which could lead to insufficient activation of the additive is caused by an overlap area compensated for the individual pulses, which is made possible by the use of high pulse repetition rates, for example in the range between 2 to 2.5 MHz.
- Another embodiment that is also particularly promising is achieved by using a contactless measuring method, in particular using electromagnetic radiation such as X-rays, to determine the position and / or orientation of at least one electronic component in the carrier material and then a deviation from the actual position and / or actual orientation is determined from the desired position and / or desired orientation and correction values for the subsequent irradiation of the carrier material by means of the pulsed laser radiation are derived therefrom and the irradiation is finally carried out taking these correction values into account.
- a contactless measuring method in particular using electromagnetic radiation such as X-rays
- the exact position and rotation of the electronic component is determined, for example, by an X-ray method, and the activatable additives or the catalytically active species are irradiated, taking the correction values into account.
- Software can be used to adapt the conductor tracks and holes to be structured to the actual position and orientation of the electronic component in the carrier material, thereby avoiding rejects and considerably increasing reliability.
- the size and / or mass of the individual filler particles contained in the carrier material is significantly larger than the size and / or mass of the individual additive particles contained in the carrier material, this is due to the size or mass differences of the filler particles and the additive particles, on the other hand, surprisingly lead to an inhomogeneous distribution of the additive and filler particles, with the result that, in the course of processing the carrier material, the comparatively large or heavy filler particles collect primarily in the inner or medial area of the carrier material, while the comparatively small or light additive particles are displaced into the layers of the carrier material close to the edge.
- the activation process can be significantly improved there, which can be carried out with low radiation intensity without the total amount of added additives having to be increased for this purpose.
- the correspondingly reduced proportion of additives in the core of the carrier material also avoids undesirable changes in other material properties.
- 3 to 15 percent by weight, preferably 6 to 12 percent by weight, of LDS additive are contained in the carrier material.
