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.

SUPPLIER COMPARISON

Thai vs Shenzhen PCB manufacturing — which side of the China+1 line?

Pick Thai-made PCB if you sell into US tariff-affected categories, ship into customers with China+1 mandates, or need a non-China origin for regulated supply-chain. Pick Shenzhen if you don't have tariff exposure, your buyer is China-domestic, and you want the fastest iteration cycle from a 100km-radius supplier ecosystem.

Side-by-side, by dimension

	FQC	Shenzhen PCB suppliers
Country / region	Thailand (Rayong) — non-China origin	Shenzhen / Pearl River Delta — China origin
US Section 301 tariff exposure	Not subject to Section 301 China list	Subject to Section 301 25%+ on PCB HTS codes
China+1 supply-chain mandate	Eligible — full non-China BOM origin documentation	Not eligible without parallel non-China line
Capability ceiling (HDI)	5th-order any-layer (FQC Thailand) — production	Top Shenzhen Tier-1 (Shennan/WUS): 5th-order; Tier-2 ceiling 2nd-order
Supplier density / ecosystem	Building — Thai PCB cluster still maturing 2024-	Highest in the world — 100km-radius full PCB supply ecosystem
Lead time	2-4 weeks HDI proto; 4-6 weeks production	Often 1-2 weeks proto for stocked stack-ups (ecosystem advantage)
Labor / cost base	Thai labor — slightly higher than Tier-2 China; well below US	Tier-2 China baseline — lowest among comparable HDI capability
Customs / shipping origin	Made in Thailand — clean origin for US/EU customers	Made in China — additional documentation for sensitive sectors
IP / supply-chain audit posture	Thai jurisdiction; Western buyer audits well-received	China jurisdiction; certain US-customer audits restricted
Best-fit volumes	Mid-to-high volume regulated programs	Anywhere from proto to mega-scale, when origin is fine

When to pick FQC

·You ship into US end-customers with Section 301 tariff exposure on China-origin PCBs.
·Your customer's BOA / supply-chain board mandates China+1 for risk-tier-1 components.
·You need automotive (IATF 16949) or medical (ISO 13485) regulated production, non-China origin.
·You want IP / supply-chain audits in a Western-friendly jurisdiction without losing East-Asia cost discipline.

When to pick the competitor

·Your buyer is China-domestic and tariff origin doesn't matter.
·You need the fastest possible prototype loop and live within the Pearl River Delta supply ecosystem.
·Your absolute lowest BOM cost target overrides geography and audit risk.
