I. Company Overview at a Glance
998 PCB Group is a national high-tech enterprise specializing in the R&D, manufacturing and sales of high-density interconnect (HDI) and multilayer printed circuit boards. Headquartered in Shenzhen — China’s electronics manufacturing hub — the group has spent nearly two decades building an integrated production network that now reaches customers across Europe, the Americas, Japan, South Korea and the wider Asia-Pacific region.
- Founded: 2006 (Shenzhen)
- Annual output value: over RMB 1 billion
- Employees: 2,000+
- Annual PCB capacity: 3,000,000 m² (2.8M m² rigid multilayer + 0.2M m² flex and rigid-flex)
- Manufacturing parks: Jiangxi (300 mu) and Anhui (100 mu), 400 mu total planned area
- Core positioning: HDI, 2–30 layer multilayer PCB, FPC, rigid-flex and high-speed high-frequency boards
Season PCB is the group’s international brand and single point of contact for overseas customers: English-speaking engineering support, USD invoicing, and DDP shipping to major markets — backed by the group’s full-scale production system.
II. Manufacturing Bases and Annual Capacity
Two Dedicated Industrial Parks, Purpose-Built for PCB
The group operates self-built PCB industrial parks rather than renting scattered facilities. The Jiangxi park covers 300 mu (~50 acres) and the Anhui park covers 100 mu, for a combined planned area of 400 mu. Phase I is fully operational; Phase II — additional standardized production buildings, office towers and staff housing — is scheduled for completion by the end of 2026, further expanding capacity headroom for long-term partners.
Imported Equipment Portfolio
Production lines are equipped with machinery sourced from the United States, Germany and Japan, including:
- Large-format mechanical drilling and CO₂ laser drilling systems for microvia formation
- Full-auto electroplating lines and immersion gold (ENIG) lines
- OSP and immersion silver surface-finish lines
- LDI (laser direct imaging) for fine-line patterning
- Fully automatic electrical test (flying probe + fixture test) and AOI/VCP inspection
This equipment base is what allows the group to hold 1.8/1.8 mil line width/spacing, 0.075 mm minimum blind via, and reliable via resin plugging (VPPL) — the process trio behind today’s smartphone-class and automotive-grade HDI designs.
III. Core Products and Process Capabilities
The product portfolio covers the full spectrum of rigid, flex and hybrid technologies:
| Product Line | Key Capability | Typical Applications |
|---|---|---|
| HDI PCB (up to 4-stage) | Laser microvia 0.075 mm, stacked/staggered vias, resin plugging, any-layer HDI | Smart cockpit, smartphone, module boards |
| 2–30 layer multilayer PCB | 1.8/1.8 mil lines, heavy copper up to 3 oz inner layers, back drilling | Industrial control, servers, power electronics |
| FPC & rigid-flex PCB | 2–8 layer flex, rigid-flex lamination, dynamic flex grades | Wearables, medical sensors, automotive |
| High-speed / high-frequency PCB | Rogers, Taconic, PTFE hybrid layups; controlled impedance ±5% | 5G AAU, radar, baseband, optical modules |
| Metal core / aluminum PCB | 1–4 layer, thermal conductivity up to 2.0 W/m·K | LED lighting, power supplies |
Representative Build: 12-Layer 2-Stage HDI Automotive Core Board
One build that illustrates the group’s HDI capability is a 12-layer 2-stage HDI core board for automotive smart-cockpit and center-console systems:
| Item | Specification |
|---|---|
| Layer count / structure | 12 layers, 2-stage HDI (2+8+2) |
| Base material | FR-4, Tg 170 °C |
| Board thickness | 1.6 mm |
| Panelization | 120 × 102 mm / 4-up |
| Copper thickness | 1 oz outer / 0.5 oz inner (2 oz on L6 & L7) |
| Minimum through via / blind via | 0.20 mm / 0.10 mm |
| Line width / spacing | 2.5 / 2.5 mil |
| Minimum BGA pitch support | 0.25 mm |
| Surface finish | ENIG 1–2 µ” |
| Special process | Via resin plugging (VPPL), heavy copper inner layers |
Boards like this pass the automotive-grade audits required by tier-one suppliers — the same production lines are available to your prototypes and volume orders through fast-turn PCB prototype services.
IV. One-Stop PCBA and SMT Services
Bare-board manufacturing is only half the story. Through its dedicated assembly division, the group runs advanced SMT placement and PCBA lines — including Fuji NXT high-speed placers — offering a genuine one-stop flow:
- DFM review — engineering feedback on stackup, impedance and manufacturability before production
- PCB fabrication — in-house, on the lines described above
- Component sourcing — franchised distribution channels with full traceability and anti-counterfeit screening
- SMT / THT assembly — 01005 components, BGA, QFN, PoP; leaded and lead-free profiles
- Test & inspection — AOI, X-ray for BGA, ICT and functional test on request
- Conformal coating, programming & final packing — ready-to-ship semi-finished or boxed products
For overseas buyers this collapses a 4-supplier supply chain into one PO with one quality owner — typically cutting 30–50%% off total turn-around time versus coordinating a board house and an EMS separately.
V. Quality System and Certifications
The group’s quality infrastructure is audit-ready for automotive and medical customers:
- ISO 9001:2015 — quality management system
- ISO 14001:2015 — environmental management system
- IATF 16949 — automotive industry quality management
- UL recognition — safety-certified laminate systems and finished boards
- IPC Class 2/Class 3 workmanship per IPC-A-600 and IPC-A-610
Every order ships with a full documentation package on request: layer stackup report, impedance coupon test report, flying-probe/fixture test report, cross-section micrographs and CoC. Green manufacturing is also on the roadmap — closed-loop water treatment and low-emission surface finishes are standard across the newer park lines.
VI. Industries and Applications Served
Products from 998 PCB Group are designed into communication infrastructure, computing, smart home, automotive electronics, medical instrumentation and aerospace programs. On the consumer side, the group is an approved supplier in the supply chains of leading communication and consumer-electronics brands — a reference point that shortens vendor-qualification cycles for new customers.

| Medical devices | Rigid-flex, HDI wearables | Traceability, fine-pitch assembly |
| Aerospace | High-reliability multilayer | Class 3 workmanship, full CoC package |
VII. Why Global Buyers Choose 998 PCB Group
- Scale with flexibility. 3,000,000 m²/year capacity absorbs volume spikes, while the prototype cell keeps first articles moving in as little as 24–48 hours.
- Real HDI depth. Up to 4-stage HDI with any-layer capability — not subcontracted, but produced on in-house laser-drilling lines.
- One quality owner from PCB to PCBA. Board fab, SMT and functional test under one ISO/IATF-certified roof.
- Transparent engineering communication. English-speaking FAE team (via Season PCB) responds within hours, not days.
- Stable, audited supply chain. Self-built parks and imported equipment reduce dependence on third-party capacity — an advantage that proved decisive during recent industry capacity crunches.
