A modest uptick at the showroom becomes a roar at the foundry. Each tier pads estimates to avoid stockouts, distorting reality at the source. That echo created historic backlogs and volatile pricing. Transparent data sharing and aligned incentives can quiet the whip, but trust takes time, and time was the one commodity nobody had in surplus.
OSAT capacity, ABF substrates, wire-bond frames, and test sockets rarely make headlines, yet they decide what ships. When substrate lead times stretched, finished dies languished. Investment lagged demand because margins seemed modest—until they weren’t. The lesson is unmistakable: resilience requires attention to unglamorous links, proactive commitments, and longer-term partnerships that outlast the panic of the moment.
