Abstract

FIELD: technologies for processing of dielectric surfaces before application of metal coating. SUBSTANCE: method may be used for manufacturing of printed circuit boards, flexible printed cables, flat off-set printing forms. Method involves degreasing dielectric surface, processing in ammonium water solution of copper sulfate, filtering, thermal processing and washing. Substrate is dried after application of activating solution and before thermal processing. Ammonium is introduced in solution of copper sulfate after filtering and mole ratio of activating solution is Cu:NH=1:3,5-4,0. EFFECT: increased uniformity, decreased resistance of applied activating layer.

Изобретения относится к технологии активирования поверхности диэлектриков перед химической и/или электрохимической металлизацией и может быть использовано для изготовления печатных плат (ПП), гибких печатных кабелей (ГПК), плоских офсетных печатных форм (ПОПФ), а также для неизбирательной металлизации пластмасс и керамики. Цель - решается задача повышения степени однородности и электропроводности нанесенного слоя активатора перед металлизацией. Сущность изобретения состоит в том, что поверхность диэлектрика подвергают обезжириванию, последующей обработке в водном аммиачном растворе фосфорсодержащей соли меди, фильтрованию, термообработке и промывке, причем сушку подложки с нанесенным активирующим раствором проводят перед термообработкой, аммиак вводят в раствор фосфорсодержащей соли меди после фильтрования, а активирующий раствор берут в мольном соотношении Си2+:NH3=1:3,5-4,0.The invention relates to a technology for activating the surface of dielectrics before chemical and / or electrochemical metallization and can be used for the manufacture of printed circuit boards (PP), flexible printed cables (GPC), flat offset printing forms (POPF), as well as for the non-selective metallization of plastics and ceramics. The goal is to solve the problem of increasing the degree of homogeneity and electrical conductivity of the deposited activator layer before metallization. The essence of the invention lies in the fact that the surface of the dielectric is subjected to degreasing, subsequent processing in an aqueous ammonia solution of a phosphorus-containing copper salt, filtration, heat treatment, and washing, moreover, the substrate with the applied activating solution is dried before heat treatment, ammonia is introduced into the solution of the phosphorus-containing copper salt after filtration, and the activating solution is taken in a molar ratio of Cu 2+ : NH 3 = 1: 3.5-4.0.
