Dashboard PET Membrane Switch Keyboard With FPC Circuit 
 
embrane flexible circuits use flexible materials + conductive silver paste/insulating layer printing process to form integrated circuits with conductive functions. Adding insulating layers/wear-resistant insulating carbon pastes and other materials to the printed circuits to increase the anti-oxidation and resistance of flexible circuits.
Durability, also adding wire key/metal dome/hot embossing process to create operability without adding external keys;
Structure: flexible polyester film + conductive silver paste + upper and lower lines (wire key interlayer / metal shrapnel / hot embossing);
Material: PET polyester film + silver-winning material with excellent electrical conductivity + carbon paste material with good wear protection, all of which meet the requirements of environmental protection Rohs;
