Various high-temperature polymer materials were preconditoned by wet-chemical methods and ion-assisted plasma processes, respectively. The polymer surfaces were investigated by SEM, AFM and stylus profilometry. The adhesion strength was controlled by a peel test. Measurement of the specific electrical conductivity, helium gas tightness and soldering experiments provide valuable information concerning possible applications. Using wet-chemical methods, filler particles like mineral compounds are normally dissolved completely. A mechanical anchoring in remaining holes provides peel strength values of more than 1 N mm(-1) after thermal ageing. In contrast to this, plasma-etching processes attack the polymer material preferentially. Therefore, mineral particles must still adhere strongly to the polymer to provide mechanical adhesion sites for the metal layers. An adhesion strength of about 1 N mm(-1) was obtained likewise on different substrate materials. (C) 1999 Elsevier Science S.A. All rights reserved.
