Bus Bars in conjunction with transparent conductive coatings are used for e-connectivity systems such as ITO heater windows, EMI shielded displays, and incubators. Anti-fogging, thermal control, EMI shielding and anti-static are all managed by utilizing ITO/IMITO coatings and silver or gold bus bars applied to glass specialty or technical glass substrates.

Transparent conductive coatings such as indium tin oxide (ITO), indium molybdenum (IMO) or index-matched (IMITO) are used to make robust transparent electro-magnetic shielded (EMI) display enhancement glass, anti-fogging/frost-free camera windows and controlled temperature sample surfaces for live cell imaging. Bus bars provide the pathways for electrical connectivity or grounding points to the coating and are themselves made of conductive material.

Bus bars are offered in strip, full perimeter and other controlled patterns either on top of or under the coating with connection point options possible at the surface, side or rear surface. Abrisa Technologies’ total solutions include transparent conductive coatings, bus bars and wire bonding on the supply of fabricated specialty and technical glasses.
