METHOD FOR PRODUCTION OF A CONDUCTOR TRACK STRUCTURE AND A CORRESPONDINGLY PRODUCED CONDUCTOR TRACK STRUCTURE

摘要

The invention relates to a method for production of a support material (2) in currentless metallization baths and a conductor track structure (1) correspondingly produced on the support material (2). The sheet of support material (2) is firstly subject to a selective electromagnetic radiation (3) from a Nd:YAG laser to generate the conductor track structures (1) on the support material (2) in the form of highly reactive aluminium particles by the decomposition of non-conducting aluminium nitride which is finely dispersed in the support material (2). Nitrogen is simultaneously released which prevents an undesirable oxidation of the aluminium particles. At least one copper layer is then currentlessly deposited on the conductor track structure (1). An accelerated process for generation of adhered metallisation of a surface structure in currentless baths is thus achieved.
