Conductive Compounds Inc., a Hudson, NH (USA) based manufacturer of specialty materials for printed electronics and electronic assembly industries announces a new series of specialty carbon inks called VRI (Variable Resistance Inks).
VRI carbon inks are used to manufacture printed rheostats, potentiometers, printed discrete resistors to replace surface mounted discrete components, as well as other electronic devices exposed to mechanical abrasion. VRI inks are available in different resistance ranges, and can be blended to get precise, linear and repeatable resistance values. Conductive Compounds’ VRI inks have exceptional resistance to mechanical abrasion, and will withstand more than 1 million linear or rotary abrasion cycles without losing significant electrical resistance. VRI inks have outstanding electrical resistance linearity, Output Smoothness (OS), Total Resistance (TR) and Contact Resistance Variance (CRV), even when exposed to over 1 million abrasion cycles and heat/humidity cycling.
VRI inks can be applied by stencil or screen printing processes and have excellent adhesion to PET (polyester) and polyimide films, FR4, copper and printed silver ink conductive traces as well as a variety of other substrates. VRI inks are available in different standard resistance ranges, and are designed for blending to achieve intermediate values or to obtain even more precise electrical resistance tolerances. Resistance values for VRI ink, as supplied, have a tolerance of +/- 5% from lot to lot.
VRI inks are functional replacements for Minico and other carbon inks used in the manufacture of potentiometers and rheostats for automotive controls, joysticks for video games and controllers, lighting controls and industrial controls. “Conductive Compounds Inc. is committed to offering engineered products to meet the demands for new or improved printed electronic technology worldwide, and the VRI ink series is an exciting new addition to our expanding portfolio of products” notes Don Banfield, Product Manager of Conductive Compounds Inc. “The VRI series provides better wear resistance than other carbon ink products currently available in the marketplace.”
All Conductive Compounds Inc.’s R&D and manufacturing is done in the USA at its Hudson, NH facility. Products are generally shipped within 48 hours after an order is received.
