Step 03 · Inner Layer Fabrication

Inner Layer DES Systems

Develop, etch, and strip inner-layer cores in a single horizontal wet process line — the highest-impact step in any multilayer PCB fab. Uniformity > 97 %, etch factor > 4.0, 0–5 m/min adjustable line speed.

Thin Core Transport

Optimized manifold geometry maintains uniform trace definition down to 25 micron line widths across large-format panels.

Continuous chemical analysis and automatic replenishment ensure consistent etch rate across multi-shift fabrication runs.

Ultra-low-tension segmented rollers carry flexible and ultra-thin substrates down to 0.05 mm thickness safely.
