ABF substrate supply is full through Q4 2026, making packaging capacity a hard constraint
Funda data relayed by pequityresearch says tier-one and tier-two ABF substrate makers are full through the fourth quarter of 2026, with lead times reaching 48 to 52 weeks. Separate Digitimes reports say AMD’s chief executive went to Taiwan seeking more foundry, packaging, testing and substrate capacity. The constraint can limit accelerator shipments even when end demand remains strong.
