PCBs utilizes the design logic of printed circuit boards, reworking antenna schematics into sculptural forms using ferrochloride etching. Every copper trace alters magnetic resonance, reflecting the precision of antenna engineering. These enlarged circuits speculate on unfamiliar electromagnetic architectures, where signal paths imply spatial function. To the trained eye, copper traces might reveal domestic or commercial use—each pattern a signal map for specific environments. PCBs invites viewers to decode these signals, suggesting new imaginary spaces inscribed within the visual grammar of industrial technology, blurring the line between utility, data, and abstract spatial design.
