A Taiwanese chip supply-chain executive is publicly slamming PCB maker Unimicron over accusations it disguised where its products were made, warning the whole industry's reputation is at stake.

• Unimicron, a major printed circuit board maker, is accused of "origin laundering" — passing off goods as made somewhere they were not.
• Gudeng Precision chairman Chiu Ming-chien said Taiwanese firms make big money only because Western customers trust them.
• His line was blunt: companies that fake product origin have too much time on their hands.
• He tied Taiwan's fast economic growth directly to that trust, saying the country's foundation gets destroyed without it.

Outlook: Expect more scrutiny of Taiwanese suppliers' origin claims as Western buyers tighten checks on where chips and boards actually come from.
