Flexible Coating Paste and Flexible solder resist Ink
This is two-components type paste for insulation coating and solder resistance.
It is most suitable for PI and PET film because it has excellent adhesion, humidity resistance, flexibility, soldering resistance, and easy operation.
SFR-300 Series shall be recommendable to a part required by superior soldering resistance.
