Plated and Non-Plated Through Hole: PTH vs NPTH Design Guide
A plated through hole (PTH) carries a conductive copper wall that links board layers. A non-plated through hole (NPTH) is drilled but left bare, so it serves mechanical needs only. Both pass through the full board thickness, and the spelling 'thru-hole' means the same thing. See also Flexible PCB Manufacturer for related specifications.

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?
