Adhesives for Applications in Optoelectronics

Optoelectronics comprises all products and processes that enable the conversion of electrical signals into optical signals and vice versa. 

Special adhesives are used to manufacture optoelectronic products. For example, optically transparent and non-yellowing adhesives are used as glob tops for diodes or LEDs. Panacol products are filled with special nanoscale filler particles, which have the advantage that they do not impair the optical properties and at the same time greatly improve the mechanical properties of the adhesive.

Panacol offers various epoxy resin-based adhesives specifically for fixing and aligning photodiodes and optical fibers for recording optical signals.

All adhesives exhibit low thermal expansion and stress on the underlying fine electronics, as well as good resistance to chemicals and the influence of media. In addition, the properties of the adhesives for optoelectronics are designed to have low shrinkage and low outgassing.

For small LEDs, adhesives are used both to attach the LED modules to the circuit board (red adhesive) and to encapsulate the chips with transparent adhesive (shown here in blue)
