A ten-company map of Korea's AI PCB and substrate ecosystem: Samsung Electro-Mechanics, Isu Petasys, Daeduck Electronics, Simmtech, Korea Circuit, TLB, Doosan Electronic BG, Kolon Industries, Pamicell and Taesung.

The market often frames AI hardware as a sequence: GPU first, then memory, then substrates. That is only partly right. AI infrastructure is now a rack-scale system made of GPUs, CPUs, DPUs, NICs, switch ASICs, memory modules, power boards and low-loss CCL. Every chip expansion needs a board. This sector thesis connects Samsung Electro-Mechanics, Daeduck Electronics, Doosan Electronic BG, Kolon Industries and Pamicell to the same system-level bottleneck.
