Optical bonding signifies for us full- surface transparent bonding of touch sensors to a cover glass and display to make a complete unit. You can select between various types of glass, customised printing and the PCaP sensors that are right for your project.The available variants of optical bonding are lOCa, OCa and air-gap bonding.lOCa and OCa bonding prevents paral- lax between the front glass, the sensor and the display and improves device structure in terms of functionality, sta- bility and optics.

In the ISO-classified controlled area, our employees install the full-surface lami- nated touch screens into enclosures, or onto supporting plates or monitor front assemblies. These can be optio- nally moulded and then submitted to 100 percent testing. Moulding is accom- plished either fully automatically on a metering system developed specially for bOPla or with manual metering using pneumatic dispensers.Our air-conditioned ISO-classified con- trolled area is operated by means of a special ventilation system.

In addition, front membrane keypads and displays can also be installed in standard and customised enclosures.

Full-surface touch screen lamination is performed only in the cleanroom (ISO clean room class 6). The pre-assembled and pre-cleaned touch screens are fed into the clean- room via a materials airlock for further processing, i.e. lamination. On the laminators, lamination can be performed using a roller with either a hard or soft rubber surface, depending on the touch screen type (capacitive/ resistive and equipped with snap domes). The laminating jigs are made in our own special department and consist of various conductive and non-conductive plastics.
