Notes:
The paper is a report on a newly developed materialand on technological studies which open up new methods for the combined application of laser andcomputer technology for advanced industrial applications, e.g., for the laser direct imaging ofconducting paths, circuit structures in printed circuit boards and probably also in mouldedinterconnection devices. The process uses — instead of copper andphotoresists — layers of a special polymer poly(bis-alkylthio-acetylene),PATAC, in which leads or conducting organic structures will be written by laser-induced localconversion of PATAC into conductive polymer tracks. The organic leads obtained can be reinforcedby electroplating if necessary. It is a purely additive process, which works without etching, thusavoiding environmental problems. The new material and technology also allow the direct imaging ofresistors, capacitors and inductors on to printed circuit boards and make it possible to make chips andother electronic components conductive. It enables the production of leads in the 10 µm scale andfor this reason is suitable for hybrid technology. The new technology is not restricted to one plane andcan, therefore, also be used for 3-D boards or MIDs.
