AutoCAF2+™

After 2 years of research and development, we are proud to introduce the next generation of Conductive Anodic Filament Monitoring equipment used to measure the influences of sub-surface electro-chemical reactions, the AutoCAF2+™ .
AutoCAF2+™ is able to measure up to 256 individual measurement sites under conditions of high humidity and temperature in accordance with IPC-TM-650 2.6.25 Test Method & IPC 9691 CAF Test Users Guide.
Conductive anodic filament (CAF) failure is copper corrosion within a printed board. It is electro-migration of the copper from Anode to Cathode between two conductors of different potential, whereas growth from Cathode to Anode is a dendrite.
A combination of bias voltage and high humidity enhance CAF failures. Electrical failure results when a filament grows between electrically isolated nets. See IPC-9691 for further information on CAF.
The NEW AutoCAF2+™ was developed in conjunction with a major CAF research project conducted by the British NPL.
