Full Turnkey PCB Assembly | Ring PCB

Ring PCB delivers Full Turnkey PCB Assembly—from PCB fabrication and component sourcing to SMT/THT assembly, testing, and shipping—so you get production-ready boards with one accountable partner.

What is Full Turnkey PCB Assembly?

Full Turnkey PCB Assembly is an end-to-end manufacturing model where a single supplier manages PCB manufacturing, BOM procurement, stencil & tooling, assembly, inspection/testing, and logistics. You send design data (Gerber/ODB++, BOM, pick-and-place/CPL, assembly drawings), and we return finished, tested PCBA ready for integration.

Why Ring PCB

• 17 years of PCB & PCBA specialization; 500 employees focused on quality and on-time delivery.

• Two self-owned factories in Shenzhen and Zhuhai with 5,000+ m² modern lines.

• Certified to ISO9001, ISO14001, ISO13485, IATF16949; builds to IPC-A-610 Class 2/3.

• Rapid cycles: 3-day functional prototype, 7-day volume build (typical, design-dependent).

• Global reach: exports to 50+ countries/regions with robust supply-chain and traceability.

• Industry customization: automotive, medical, industrial control, telecom/5G, consumer, energy, and more—custom printed circuit boards and assemblies tailored to compliance and reliability needs.

• Advanced QA: 3D AOI, X-ray (BGA/uBGA), flying-probe/ICT/FCT, full DFM/DFT support.

• Cost control at scale—optimized panelization, approved alternates (AVL), and lifecycle risk checks.

We specialize in turnkey PCB assembly for complex designs—HDI, high-layer count, rigid-flex, controlled-impedance, high-current, and high-reliability builds.

Key Features & Advantages

• One PO, one schedule, one warranty—fewer handoffs, faster launch.

• DFM/DFT reviews before build to prevent re-spins and improve yield.

• Trusted component sourcing from authorized channels; automated alternates proposal.

• Process transparency: traveler records, lot/barcode traceability, certificates on request.

• Scalable from 1 to 100k+ units with the same quality system and documentation set.

• Design confidentiality safeguarded by controlled access and NDAs.

Technical Challenges We Solve

• Fine-pitch & dense packaging: 01005 passives, 0.3 mm-pitch BGA/uBGA, QFN with thermal vias.

• Thermal & power: thick copper (up to 6 oz), aluminum base, thermal modeling & reflow profiling.

• Signal integrity: impedance-controlled stackups, low-loss laminates (e.g., Rogers/PTFE, hybrid).

• Mixed technology: SMT + THT + press-fit; selective wave, hand insert, conformal coating.

• Compliance: lead-free RoHS/REACH, medical documentation, automotive PPAP on request.

• Test strategy: boundary-scan, fixture design (ICT/FCT), firmware flashing, burn-in.

Typical Specifications & Capabilities

Process—How We Work (End-to-End)

1. RFQ & DFM/DFT review: risk analysis, stackup proposal, test strategy.

2. Sourcing: AVL validation, lifecycle/obsolescence check, alternates approval.

3. PCB fabrication: controlled-impedance builds, coupons, FAI.

4. Assembly: optimized reflow/wave profiles, moisture control, ESD-safe handling.

5. Inspection & test: AOI/X-ray, flying-probe/ICT/FCT, firmware flashing, system test.

6. Packaging & logistics: ESD packaging, labeling/traceability, export documentation.
