Polymer thick film technology: New possibilities for the new millennium?

The industry is increasingly confronted with the necessity of solving problems associated with the disposal of discarded goods. The impact that products have on the environment is becoming an important criterion in marketing products. On account of this the technological process steps in production of electronic devices, the use and their disposal have to be environmentally acceptable. The whole system must meet the requirements of ecological compatibility. In complying with this the variety of material should be reduced and the reliability of the applications must be increased. One contribution to comply with these requirements is the use of Polymer-Thick-Film-Technology (PTF) for tracks, because the patterning should take place in principle without endangering the environment through chemical treatment The use of flexible inks on flexible Silicone substrates without harmful flame retarding chemical substances makes the whole circuit board especially Eco-friendly and allows the construction of a space-saving 3D-package.
