3.3.2. Thermal effect limitation
After removing the polymer matrix it was proved that in both cases a double
line, centered on the area of engraving, is obtained. This confirms the same
behaviour that has been reported recently for the fabrication of silver wires
[13].
The double line is characterized by the width, measured at the half-maximum,
and the distance between lines, measured between the ridges inside of the
double line (Figure 20).
