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.

01 · AI / Server

AI, Server & Data Center

MARKET CONTEXT

AI training clusters and 800G/1.6T optical modules have reset the PCB spec bar in 2024-2026. Backplanes, accelerator carriers, and CPO midplanes now demand 40+ layer counts, sub-25 μm lines, and ±5% impedance across every pair. Demand is capacity-constrained — the bottleneck is not design, it's fabs that can actually hold those specs in volume.

FQC CAPABILITY FIT

■Up to 100 layers, validated on parent 42L ATE test board (2024 Guangdong Outstanding Hi-Tech Product).
■5th-order any-layer HDI to 16L — 3+4+3 HDI qualified for 800G optical modules.
■Megtron 7/8, Taconic RF-35 in regular production; ±5% impedance on every pair.
■ISO/IEC 27001:2022 — signed Gerbers stay in-house.

02 · Automotive

Automotive & EV

MARKET CONTEXT

ADAS, 77 GHz radar, BMS, and high-voltage inverters dominate the EV bill-of-materials. Auto customers will not onboard a fab without IATF 16949 and 15+ year field-reliability data. Thai production also dodges the US tariff schedule on China-origin PCB — a live issue for 2026 ship-to-NA programs.

FQC CAPABILITY FIT

■IATF 16949:2016 certified, triple-stacked with ISO 9001 and QC080000 on the same line.
■15 oz UL-listed outer-layer, 13 oz multilayer for BMS bus-bars and inverter DC rails.
■Rogers RO3003 qualified for 77 GHz radar; Megtron 6 for ADAS compute.
■Multilayer rigid to 24L — standard for ADAS ECU and infotainment boards.

03 · Medical

Medical Devices

MARKET CONTEXT

Imaging, analytical, and patient-monitoring OEMs buy on traceability, not price. A 15-20 year product lifecycle means the fab must hold the same spec for a decade — material changes require re-qualification. Aging populations across Japan, EU, and North America are pulling demand through, especially for outpatient diagnostic instruments.

FQC CAPABILITY FIT

■ISO 13485:2016 certified for medical device quality management.
■IPC-A-600 Class 3 workflow available; full panel serialization and lot traceability.
■Low-outgassing material options (polyimide flex, high-Tg FR-4) for sealed enclosures.
■Proven on 15-20 year lifecycle programs with Japanese analytical OEMs.

04 · Industrial

Industrial Control, Robotics & FA

MARKET CONTEXT

PLCs, servo drives, CNC controllers, vision sensors, industrial comm — the workhorse of Japanese factory automation. High-mix, low-volume, ruthless on audit rigor, forgiving on unit price if you hit the spec. Industrial control is the largest revenue slice at parent co (≈50%) precisely because it rewards exactly the discipline FQC is built around.

FQC CAPABILITY FIT

■20+ years continuous supply to Japanese FA OEMs — founder trained at Tokyo University.
■High-mix low-volume line configuration; 50,000 m²/month Phase 1 capacity.
■IATF 16949 + ISO 9001 + QC080000 on one line — rare at a Thai fab from day one.
■Full Gerber-to-shipment traceability; 1.7% workforce turnover protects process memory.

05 · Power / Telecom

Power, Solar & Telecom

MARKET CONTEXT

Solar inverters, EV charging piles, 5G massive-MIMO, and industrial power supplies all push current density and thermal margin beyond what 6 oz copper can handle. 5G mmWave has also pushed base-station PAs into the 28-40 GHz band, where material loss and impedance control define yield.

FQC CAPABILITY FIT

■15 oz UL-listed outer-layer and 13 oz multilayer heavy copper — 15% above the PCBWay ceiling.
■Thermal-via arrays rated to 400 A for inverter DC rails and charger busbars.
■40 GHz high-frequency flow on Rogers RO3003 / Taconic RF-35 for 5G PAs.
■UL listing in place for heavy-copper safety-critical applications.
