摘要：

Different analytical procedures were developed to investigate the chemical composition of printed wiring boards. A set of 11 samples from different electronic devices were ground and prepared for ICP-AES and AAS analyses by extraction with aqua regia and microwave digestion. Several sample preparation techniques were used for the analyses by EDXRF; the best results were obtained by embedding the samples in Vaseline. Since no standard reference material is available for printed wiring boards, a model reference material was created to compare the applicability and limitations of the employed analytical techniques.
