Printed electrical insulation: the role of the dielectric layer
A dielectric ink is screen-printed between two conductive layers to provide printed electrical insulation: it prevents short circuits where tracks cross and allows several levels to be stacked in a multilayer circuit. The dielectric varnish is selected according to the associated conductive ink, the substrate and the constraints of the device: flexibility, thermal resistance, curing compatibility.
VFP formulations are developed to work with the silver and carbon conductive inks of the range, on flexible printed circuits as well as rigid substrates. Exact characteristics are given in the technical data sheet of each grade.
Selecting a dielectric grade
A dielectric layer is selected together with the associated conductive inks, substrate and the complete curing cycle. For a multilayer or flexible circuit, compatibility between layers, adhesion and processing conditions must be checked for the grade and final assembly.

Grades and technical data sheets to consult: ECV003 (TDS), ECV004 (TDS).
Selection questions
- How can the appropriate grade be confirmed?
Compare the required function, substrate, process and curing conditions with the grade’s technical data sheet, then qualify the actual assembly.
