Creative Materials has introduced two new conductive and resistive ink products: 126-33, a new silver-filled electrically conductive ink, and 126-28, a low-resistance carbon ink.
Typical applications include biomedical applications, biosensors, electronic component manufacturing, RFID antennas, EMI/RFI shielding of polyimide flexible circuits, polymer thick film circuitry, membrane switches, printed heaters, and resistive elements/coatings.
The conductivity rating of 126-33 is 0.008 Ω /square/mil (sheet resistivity), with a volume resistance of 0.00002 Ω-cm. The conductivity allows the end-user to print narrower and/or longer circuit trace lines or thinner coatings without compromising overall maximum ohm values. Conductive inks are especially useful for EMI troubleshooting.
The 126-28 resistive ink has sheet resistivity of 8 ohms/square/mil. Lower resistance can also allow for narrow print lines or thinner coatings, which consistently results in reduced cost.
Both feature adhesion to polyester, polyimide and a wide variety of high-energy surfaces. In addition, both inks offer abrasion and chemical resistance, as well as long-term aging. These inks can be applied by screen-printing, dipping, or syringe dispensing, and they cure at temperatures as low as 110°C.
