Electrochemical Migration Resistance Test
1 ScopeThis test method provides a means to assess thepropensity for surface Electrochemical Migration . This testmethod can be used to assess soldering materials Applicable IPCIPC-B-25 Multipurpose Test BoardIPC-B-25 AMultipurpose Test BoardIPC-6012 AQualification and Performance Specification forRigid Printed BoardsIPC-9201 Surface Insulation Resistance American Society for Testing and Materials (ASTM)ASTM D-257-93 Standard Test Methods for DC Resistanceor Conductance of Insulating Materials3 Test SpecimensIPC-B-25 (B or E pattern) or IPC-B-25A(D pattern) test boards shall be used, with conductor linewidths and spacings of mm [ in]. The methodof manufacture should provide optimized conductor edgedefinition (refer to the Class 2 and 3 conductor width require-ments in IPC-6012).
