Description
Fremgangsmåte til fremstilling av en med et metallmønster forsynt isolerende bærer. Method for producing an insulating carrier provided with a metal pattern.
Oppfinnelsen angår en fremgangsmåte The invention relates to a method
til fremstilling av en med et metallmøn-ster, f. eks. i form av en trykket strøm-krets, forsynt isolerende bærer, i hvilken metallmønsteret dannes ad galvanisk vei for making one with a metal pattern, e.g. in the form of a compressed current circuit, provided with an insulating carrier, in which the metal pattern is formed by galvanic means
på en til det ønskede mønster svarende delvis dekket, midlertidig, metallisk bærer og deretter overføres på den isolerende bærer. on a to the desired pattern corresponding to the partially covered, temporary, metallic support and then transferred to the insulating support.
Et slikt metallmønster kan ha form av Such a metal pattern can take the form of
en strømkrets for ledning av den elektriske strøm i radio- og fjernsynsapparater, rør-apparatur, elektroniske regnemaskiner, te-lefonsentraler osv., og det kan også ha form av visse enkelte deler, f. eks. kondensato-rer, spoler, motstander og liknende. a circuit for conducting the electric current in radio and television sets, tube apparatus, electronic calculators, telephone exchanges, etc., and it may also take the form of certain individual parts, e.g. capacitors, coils, resistors and the like.
Ved en kjent fremgangsmåte av den By a known method of it
forannevnte art blir den midlertidige bærer dannet av en stålplate som viser det ønskede mønster i høyrelieff, slik at altså de dekkede deler er utformet fordypet. Det på høyrelieffdelene utfelte metallmønster trykkes inn i en termoplastisk bærer, hvoretter metallmønsteret trekkes fra stålplaten sammen med denne termoplastiske bærer. in the above-mentioned manner, the temporary support is formed from a steel plate showing the desired pattern in high relief, so that the covered parts are designed recessed. The metal pattern deposited on the right-relief parts is pressed into a thermoplastic carrier, after which the metal pattern is pulled from the steel plate together with this thermoplastic carrier.
Når det anvendes klebestoffer for å få When adhesives are used to get
metallmønsteret til å hefte til den isolerende bærer opptrer det ofte, særlig når det benyttes herdbare klebestoffer, en hefteforbindelse mellom den isolerende bærer på den ene side og dekkmaterialet, eller med den midlertidige bærer på den annen side når dekkmaterialet er blitt fjernet før the metal pattern to adhere to the insulating carrier it often occurs, especially when curable adhesives are used, a bond connection between the insulating carrier on the one hand and the covering material, or with the temporary carrier on the other hand when the covering material has been removed before
overføringen av metallmønsteret på den isolerende bærer. Denne hefteforbindelse gjør det vanskelig eller ofte helt umulig å skille den midlertidige bærer fra den isolerende bærer. Ved en annen kjent fremgangsmåte blir en slik uønsket sammen- the transfer of the metal pattern onto the insulating carrier. This booklet connection makes it difficult or often completely impossible to separate the temporary carrier from the insulating carrier. In another known method, such an unwanted combination is
hefting unngått derved at det anvendes et usedvanlig dekkmateriale, nemlig en fluor-kullvannstoff-forbindelse, som virker kle-bestoffrastøtende. Anvendelsen av et så-dant materiale er imidlertid ikke helt en-kel og krever mange tidsspillende arbeidstrinn. stapling is thereby avoided by using an unusual covering material, namely a fluorine-carbon hydrogen compound, which acts as an adhesive-repelling agent. However, the use of such a material is not entirely simple and requires many time-consuming work steps.
Oppfinnelsen går ut på en fremgangsmåte av den førstnevnte art hvor en mu-lig fastheftning til den isolerende bærer ikke spiller noen rolle og hvor dekklaget kan fjernes før overføringen av metall-mønsteret. Dette har den fordel at når det anvendes en flat, altså ikke profilert midlertidig bærer rager metallmønsteret frem og kan lett overføres på den isolerende bærer. The invention is based on a method of the first-mentioned kind where a possible adhesion to the insulating carrier does not play any role and where the covering layer can be removed before the transfer of the metal pattern. This has the advantage that when a flat, i.e. not profiled, temporary carrier is used, the metal pattern protrudes and can easily be transferred onto the insulating carrier.
Fremgangsmåten i henhold til oppfinnelsen er karakterisert ved at den midlertidige bærer dannes av en metallplate som på et skillelag på denne bærer et ad galvanisk vei utfelt tynt metallag, som har en tykkelse av høyst 10 mikron, hvilket tynne metallag med metallmønsteret overføres på den isolerende bærer, hvorunder metallplaten skilles fra det tynne metallag langs skillelaget og deretter ad mekanisk og/eller kjemisk vei fjernes fra den isolerende bærer og metallmønsteret som nå danner et enhetlig legeme. The method according to the invention is characterized by the fact that the temporary carrier is formed by a metal plate which, on a separating layer, carries a thin metal layer deposited by galvanic means, which has a thickness of no more than 10 microns, which thin metal layer with the metal pattern is transferred onto the insulating carrier , during which the metal sheet is separated from the thin metal layer along the separation layer and then mechanically and/or chemically removed from the insulating carrier and the metal pattern which now forms a uniform body.
Den midlertidige underlagsplate av metall, kan bestå av rustfritt stål, hvis overflate på i og for seg kjent måte er dekket med et skillelag. The temporary base plate made of metal can consist of stainless steel, the surface of which is covered in a manner known per se with a separating layer.
Det isolerende lag kan påføres ved en hvilken som helst kjent trykkemetode, f. eks. ved silketrykk eller ad fotografisk vei. The insulating layer can be applied by any known printing method, e.g. by screen printing or by photographic means.

På denne måte fåes et slitesterkt rhodiumlag på den ytre over- lytically applied layers, e.g. a copper layer, first deposit a rhodium layer and on top of this a thicker copper layer.

I stedet for av rhodium eller en bly-tinnlegering kan det første lag bestå first layer exposed parts and on top of this a copper layer. Such metal patterns can be easily soldered. Instead of rhodium or a lead-tin alloy, the first layer may consist
av gull eller sølv. På denne måte fremstilte metallmønstere er meget motstandsdyk- of gold or silver. Metal patterns produced in this way are very resistant

Man kan også ved elektrolyse påføre et jern- eller nikkellag ovenpå det fremtredende kobbermønster. resistant to corrosion and has low transition resistance, which is important when making contacts for switches. You can also apply an iron or nickel layer on top of the prominent copper pattern by electrolysis.
Dette jern- eller nikkellag vil bevirke at metallmønsteret sitter bedre fast på det isolerende underlag. This iron or nickel layer will ensure that the metal pattern adheres better to the insulating substrate.
