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

FQC vs Sanmina — PCB-only fab vs integrated EMS + PCB supplier

Pick FQC if PCB is the technical risk in your program — high-layer-count HDI, automotive + medical dual cert, and direct dialogue with the actual fab. Pick Sanmina if you want PCB, assembly, box-build, and aftermarket consolidated under one PO with a single tier-1 EMS counterparty.

Side-by-side, by dimension

	FQC	Sanmina
Business model	Specialist PCB fabricator	Tier-1 EMS — PCB + PCBA + box-build + aftermarket
Capability ceiling (HDI)	5th-order any-layer up to 16 layers (production)	Up to high-order HDI; varies by site, often outsources HDI to specialists
Layer count ceiling	Up to 100 layers (42L award)	High-layer-count via partner fabs + own backplane lines
Certifications	IATF 16949 + ISO 13485 + QC 080000 + ISO 9001/14001/45001	AS9100 + ISO 13485 + IATF 16949 + ITAR (varies by facility)
Geography	Thailand (parent in China)	Global — 20+ countries; San Jose HQ
Pricing tier	Mid (PCB-only — no EMS markup)	Bundled — PCB cost folded into EMS quote
Direct fab dialogue	Yes — talk to FQC engineers directly	No — your interface is a program manager; PCB sub-fab is internal
Single-PO consolidation (PCB + PCBA + box)	No — PCB only, separate EMS engagement needed	Yes — full vertical EMS stack
Customer type	OEMs and Tier-1s buying bare PCB	OEMs outsourcing entire product manufacturing
Capacity / scale	88,000 m² Thai PCB fab + parent campus	Publicly-listed (NASDAQ: SANM); large global EMS
Years in operation	Thai site 2024-; parent since 1995	Sanmina founded 1980, listed on NASDAQ

When to pick FQC

·PCB is the high-risk node in your BOM and you need a specialist who lives and breathes laminate + microvia.
·You already have a chosen EMS / contract manufacturer and want to consign the bare board.
·Your program needs IATF 16949 + ISO 13485 in the same factory; you don't want EMS markup on the PCB layer.
·You want direct DFM dialogue with the fab's engineers, not a managed escalation through a PM.

When to pick the competitor

·You want PCB + PCBA + box-build + reverse logistics under a single tier-1 EMS counterparty.
·Your program already runs on Sanmina-managed supply chain — adding a separate PCB fab adds counterparties.
·Your buyer specifically requires US-publicly-traded prime EMS in the contract.
