Metal foil clad board is one of the most important basic materials for printed circuit boards,and its perfor-mance indicators have a direct impact on the use of electronic products. Volume resistivity and surface resistivity are important parameters for measuring the insulation performance of metal foil clad boards. In order to reduce the impact of sample preparation process on the accurate testing of sample volume resistivity and surface resistivity,five com-mon process methods are analyzed. The samples prepared by the heat transfer graphic method have the advantages of precise electrode size,low cost,and high success rate,which are also easy to achieve in general laboratories. After testing the volume resistivity and surface resistivity of the samples made by this method,and analyzing the test results,the reliability and feasibility of this method have been verified.
