8. New perspectives

In the field of heating at relatively low temperatures (< 400 ˚C), screen-printed resistors are beginning to develop.

The manufacture of screen-printed heating elements is carried out in a clean environment (at least class 10000). The basic equipment includes a high-precision screen-printing machine, drying equipment and a tunnel furnace with a perfectly regulated temperature profile and a controlled atmosphere (air) in terms of purity and flow. The steel must be clean and dry, and operators should only handle it with gloves to avoid surface pollution. No preparation is required before screen-printing...
