Fingerprint and Touch Sensor Assembly

Fingerprint recognition and touch sensor technology for handheld devices, such as smartphones and tablets, is a rapidly growing market segment that is constantly evolving and innovating. The adhesive applications in fingerprint or touch sensor assembly are numerous and also require highly innovative and specialized adhesive materials. Use of heat-sensitive plastics and metals, like ITO, mean elevated cure temperatures cannot be used to assemble these devices. In addition, some bonding processes require that the adhesive does not flow during attachment, can be processed at low temperatures, and provides a strong and reliable bond. Our range of liquid and film material solutions are designed to meet the bonding challenges in fingerprint and touch sensor assembly.
