Where is FQC located?

FQC operates in AMATA City Rayong, Thailand's Eastern Economic Corridor, with an 88,000 m² facility (28,700 m² production).

What PCB capabilities does FQC have?

FQC manufactures rigid PCBs up to 100 layers, with 5th-order any-layer HDI capability up to 16 layers. Materials cover high-frequency Rogers and Megtron laminates, heavy copper from 1 oz to 15 oz, and fine-pitch designs adjacent to IC substrate territory.

Is FQC certified for automotive PCB?

Yes. FQC holds IATF 16949 for automotive, plus ISO 13485 for medical devices and QC080000 for hazardous substance management — a triple-certification rare among Southeast Asian PCB manufacturers.

FQC is a wholly-owned subsidiary of Sihui Fushi Electronics (Shenzhen Stock Exchange: 300852), a publicly-listed Chinese PCB manufacturer.

Can FQC make 800G optical module PCB?

Yes. FQC was customer-qualified for 800G optical module PCB in October 2024 and is shipping in small-batch production. The 1.6T variant has also passed customer certification.

Why pick a Thai PCB manufacturer instead of Chinese?

FQC offers China+1 supply chain resilience — a Thailand-origin PCB hedges against US-China tariffs and CFIUS exposure, while the Sihui Fushi parent retains access to Shenzhen's PCB ecosystem economics, materials, and engineering depth.

Does FQC make PCB for AI servers?

Yes. AI server backplane is a primary FQC specialty, covering PCIe 5/6 backplanes and 800G Ethernet switch boards. Customers include hyperscale cloud and AI startup hardware programs.
