CCL/PCB: undersupply in high-end segment

to sustain along with technology migration

High-end CCL/PCB: expect undersupply to last till CY27 06 July 2026

We expect S/D to remain tight for high-end CCL/PCB toward late 2027/early 2028 given Equity

further migration toward HDI, relatively low yield rate/output in certain new technologies Asia-Pacific

(e.g. quartz-based solutions), and continuous capex increase with further capacity Technology

expansion by PCB vendors. Between CCL and PCB sectors, we believe the former could Mike Yang >>

CCL – copper clad laminate

Technology upgrades continue; raise EMC/TUC POs

We flag positives for EMC’s M9 (quartz-based) CCL as it boasts superior performance PCB – printed circuit board

(vs low Dk2-based CCL) based on certain criteria (e.g. Dk/Df). For the production

HDI – high density interconnectdifficulty and yield rate improvement on PCB side, we also believe it is relatively easier

to solve (vs PTFE-based CCL), along with initiatives including the adoption of more laser EMC – Elite Material
