Leading PCB firm prioritizes sustainability

FICT is positioning itself to be a true key player in the global market in testing probe cards.

“We aim to join our forces with business and technology partners to create a sustainable society.”

Seiji Miyoshi, President, FICT Ltd.

(August 2023 Interview)

Established in 1967 as the PCB business unit of Fujitsu, FICT is today an independent company that lives by the same founding philosophy to provide and develop state-of-the-art PCB solutions for global customers.

In 2001, the company invented the Organic Flip-Chip BGA Substrate (FC-BGA), a new technology that has now become a global standard in the semiconductor package substrate world. “Applying the same technology to our probe card products allowed us to develop high performance ST Board, positioning our company as a key player in the global market in testing probe cards (ST Board),” says Seiji Miyoshi, CEO of FICT.

Another technology that the company has developed is the F-ALCS (F-All Layer Connection Structure), which maximizes the wiring capacity of printed wiring boards (over 60 layers) through paste filling and metal bonding. “The distinctiveness of this technology lies in its alignment with the escalating environmental concerns of our times. Given the contemporary emphasis on sustainability, we search for alternative process solutions to reduce wastewater treatment and electricity consumption as much as possible,” says Mr. Miyoshi. “As the realm of high-speed communication pushes the boundaries, signal transmissions now soar beyond 100 GHz. However, the conventional through-hole stub introduces a disruptive interference within this wavelength. In contrast, by using our conductive paste, our any-layer IVH (Interstitial Via Hole) with a one-time lamination approach stands as a stubless solution, facilitating uninterrupted high-speed transmission.”

Given the prevalent trend of pursuing a finer wiring pitch, transitioning toward glass substrates is now becoming increasingly crucial. Through its F-ALCS technology evolution, known as G-ALCS, the company is now focusing on evolving toward laminated glass technology.

“Going forward, we aim to join our forces with business and technology partners and customers to create a sustainable society with our advanced technologies,” outlines Mr. Miyoshi.
