    摘要: The process for producing through-connected printed circuit boards or multilayered printed circuit boards with a polymer base with conductive polymers using a combined desmearing and direct metalization process (multilayering) is performed by subjecting the polymer base materials, provided with bore holes, to the following process steps:1) swelling in a per se known treatment liquid and rinsing with water;2) treatment with alkaline permanganate solution (desmearing);3) rinsing with water;4) rinsing with acidic aqueous solution (pH value about 1, rinsing time 10 to 120 s, depending on acid content);5) rinsing with water;6) rinsing with alkaline aqueous solution (pH 8 to 9.5);7) rinsing with water;8) rinsing with microemulsion of ethylene-3,4-dioxythiophene (catalyst);9) rinsing with acid (fixation);10) rinsing with water;11) coppering;12) rinsing with water; and13) drying;14) usual process steps for creating the printed circuit pattern.
