Table 2 Threshold for energy densities on PET and polyimide substrate for different sintering regions
From: Laser sintering of Cu particle-free inks for high-performance printed electronics
Substrate | Sintering regions | Estimated threshold for energy density (J/cm²) |
|---|---|---|
PET | Not sintered | <30 |
Sintered | 30–75 | |
Substrate damage | >75 | |
Polyimide | Not sintered | <25 |
Sintered | 25–50 | |
Substrate damage | >50 |
