Demand for ABF (ajinomoto build-up film) substrates continues to be strong while demand for other IC substrate and PCB products is being affected by seasonal factors, according to Unimicron Technology, a manufacturer of HDI PCBs, rigid-flex boards and substrate-like PCBs, and chip substrates including ABF and BT (bismaleimide triazine) substrates, Digitimes reports.
Shipments of PCB and certain IC substrate products have been affected by a seasonal slowdown in demand for consumer electronics devices, but ABF substrate shipments have enjoyed stable growth, Unimicron says.
