Adhesive-Free FCCL Substrates vs Adhesive-Based Substrates: 2L-FCCL vs 3L-FCCL Performance
Adhesive-Free FCCL Substrates bond polyimide (PI) directly to copper foil with no adhesive layer. Because the adhesive is removed, a 2L-FCCL avoids the CTE mismatch and internal stress that a 3L-FCCL shows. Therefore, adhesive-free vs. adhesive-based FCCL performance differs most in stability, thickness, and heat resistance. <div class="mceTemp"> What Are Adhesive-Free FCCL Substrates? An FCCL substrate is the copper-clad[...]
