摘要:
Conductor boards with well adhering conductor tracks are obtained if the substrates, which are clad on both sides with copper foils, have said cladding removed chemically or mechanically, are activated, if necessary sensitized, and are provided with a 0.05-2.0 .mu.m thick layer of nickel, cobalt, manganese, a nickel/iron or nickel/cobalt mixture in an electroless metallizing bath, a 0.5-5.0 .mu.m thick copper layer is applied in a subsequent copper bath and the conductor pattern is then built up by the standard semi-additive methods.

A mild and simple process of activating substrate surfaces for the purpose of currentless metallization comprises using organometallic compounds of elements of the groups 1B and 8 of the Periodic System of Elements whose organic moiety has at least one functional group over and above the groups required for binding the metal are used for activation.
摘要:
A simple and mild method of activating substrate surfaces for currentless metallization involves activating by means of organometallic compounds of elements of the 1st and 8th sub-Groups of the Periodic Table of Elements in which the organic moiety consists of oligomeric, prepolymeric or polymeric compounds containing double bonds.
摘要:
Primers, essentially consisting of a film former or matrix former, an additive, an ionic and/or colloidal noble metal, a filler and a solvent, are suitable for coating substrate surfaces for subsequent chemical metallization.
摘要:
The firmly adhesive metallization, in particular partial metallization, of the surface of semiconductors is possible, without pickling, by carrying out the activation with organometallic compounds of metals of the I and VIII Secondary Groups of the Periodic Table of Elements, then reducing in a conventional manner and metallization without current.

Flexible circuits are obtained in an elegant manner, without the customary etching methods, wet-chemically in accordance with the principles of semiadditive or fully additive technology by using for the activation noble metal activators and, as base material, films or flexible boards whose surface has (a) a specific total pore volume per unit area of 0.015-0.045 dm.sup.3/ m.sup.2, (b) an average pore diameter of 0.05-5.0 .mu.m and (c) an average pore depth of 0.05-4.0 .mu.m.

摘要:
Polymer membranes metallized by wet chemistry are highly suitable, for example, for the separation of inert, reactive and fermentation gases.The metallization is carried out after activation with noble-metal complex compounds which have at least two functional groups.Preferred metal coatings are those of Cu, Co and Ni.
摘要:
Activation baths containing an organometallic compound based on elements of sub-group 1 or 8 of the periodic table with a "guest/host" interrelationship are outstandingly suitable for electroless metallization of preferably non-metallic substrates. Activators of palladium compounds and cyclic crown ethers are particularly suitable.
摘要:
A mild activation process for the adhesion-activation of polyamide mouldings for electroless metallization comprises treating the substrates, successively or simultaneously, with the solution of a mixture of CaCl.sub.2, LiCl and/or MgCl.sub.2 with AlCl.sub.3, FeCl.sub.3 and/or TiCl.sub.4 in a lower alcohol and with an activator solution based on inorganic complex compounds of the formulaM.sup.n+ [E.sup.m+ Hal.sub.z.sup.- ]in whichM represents two hydrogen or alkali metal atoms or one alkaline earth metal atom,Hal represents a halogen, preferably Cl, andE represents a noble metal atom of the 1st or 8th subgroup of the periodic table, having the valency m and the coordination number z (z-m=n),or with customary colloidal or ionic systems of these noble metals.
摘要:
An elegant method for the production of printed circuit boards possessing good electrical and mechanical properties comprises activating baseplates with a solution of complex compounds of elements of sub-group I or VIII of the periodic table, then applying a resist layer, exposing this partially according to a resist pattern, dissolving away the covered parts of the resist layer with a solvent, and metallizing the bared parts in a wet-chemical metallization bath in the absence of a current.
