ABF Substrate Supply Remains Tight


Reading time ( words)

The supply of ajinomoto build-up film (ABF) substrates has been tight, and will continue to fall short of demand in the second half of 2019, Digitimes reports.

Several suppliers, including PCB makers Ibiden and Taiwan's Unimicron Technology, have plans to expand production capacity for ABF substrates while many players continue to resolve bottleneck issues to scale up their output. However, growth on the supply side will still fail to catch up with demand growth, Digitimes adds.

The Tianjin chemical blast in August 2015 sensitized the Chinese authorities to the use of cyanide in production. As a consequence, the authorities have introduced licensing with regard to the use of cyanide. In turn, this has motivated Chinese PCB manufacturers to ask suppliers for a competent cyanide-free immersion gold solution (CNF Au).
