General description
The ink has undergone electrical and mechanical testing which has shown that it is very flexible.
Features and Benefits
Low silver content paste presenting low resistivity, good flexibility and good adhesion on the mentioned substrates
Physical properties
Sheet resistivity: 15-20mΩ/square at 25μm
30-45mΩ/square at 10μm
Bending test: ink survived 3 cycles
(Substrate is creased and bent internally and externally with a 2kg weight.
The test piece has failed when the resistance reaches 10 times the initial value.)
Double curing: aging factor of -0.7%after double curing at 150°C for 15min
How water test: aging factor of -0.2% after boiling for 1hour
Preparation Note
Please mix well the paste without introducing air bubbles prior to screen printing.
Screen Printing Equipment: semi-automatic, manual
Ink Screen Life: >3 hours
Screen Types: suitable for use with polyester or stainless steel meshes in the range of 156 to 325 tpi.
Typical Drying Conditions: Dry at 130°C - 150°C for 10-30 minutes or on a belt dryer with air flow that sees 130°C-170°C for 5-10 minutes.
Clean Up Solvent: ethoxy propanol or sericol
Substrate: polyimide, PET, PEN and can also be printed on more rigid substrates such as alumina
