What "Turnkey" Really Means: Complete Accountability

Traditional Multi-Vendor Challenges

  • Finger-Pointing: PCB fab blames assembly house; assembly house blames component supplier.
  • Lead Time Uncertainty: Waiting for parts from 5 different distributors.
  • Quality Gaps: No single entity owns end-to-end quality.
  • Counterfeit Risk: Open-market brokers selling remarked or recycled components.

PCBLion's Turnkey Advantage

  • Single Point of Contact: One engineering team manages your entire project.
  • Integrated Timeline: PCB fab and assembly scheduled in parallel (saves 5-7 days).
  • Unified Quality System: ISO 9001, IATF 16949, ISO 13485 applied across all processes.
  • Supply Chain Transparency: Every component tracked from authorized distributor to your board.

Service Scope: What We Manage for You

1. Design for Manufacturability (DFM) Review

Before you commit to production, our CAM engineers analyze your design:

    • Minimum trace/space violations.
    • Aspect ratio feasibility (PTH depth vs. diameter).
    • Impedance stack-up validation (±5% tolerance for RF/high-speed).
    • BGA fan-out and escape routing.
    • Via-in-pad requirements (resin filling needed?).
    • Test point accessibility for ICT/FCT.

Output: DFM report with red-flag items and optimization suggestions (delivered within 24 hours).

2. Component Procurement: Authorized Sourcing Channels Only

Every component batch undergoes:

  1. Visual Inspection: Package integrity, date code verification, moisture barrier check.
  2. LCR Testing: Passive components measured for value accuracy (±1% tolerance).
  3. X-Ray Inspection: For ICs from non-franchised sources (detects remarked chips).
  4. Lot Code Traceability: Recorded in MES system for full supply chain visibility.

3. PCB Fabrication: In-House Control

  • No Middleman Delays: We control the PCB production schedule.
  • Quality Consistency: Same impedance test equipment (Polar CITS500s) used for all boards.
  • Fast Iteration: If assembly reveals a PCB issue, we can re-fab in 48 hours.

4. PCB Assembly: Component Handling Standards

  • ESD Control: ANSI/ESD S20.20 compliant.
  • MSL Management: JEDEC J-STD-033 moisture-sensitive component storage.
  • Solder Paste: Type 4/Type 5 for fine-pitch, stored at 2-10°C.
 

5. Testing & Quality Control: 100% Inspection

Automated Optical Inspection (AOI)

  • Pre-Reflow AOI: Detects paste printing defects.
  • Post-Reflow AOI: Identifies component placement errors.
  • Detection Rate: > 99.5% for visible defects.

X-Ray Inspection (Mandatory for BGA/QFN)

  • Purpose: Verify solder joint quality under components.
  • Acceptance Criteria: Void area < 15% per IPC-A-610 Class 2.
  • Equipment: Unicomp X7600 (2D/3D imaging).

Functional Circuit Test (FCT)

  • Custom Fixtures: Test jigs based on your test plan.
  • Test Coverage: Power-on, I/O, communication protocols.
  • Data Logging: Results stored in MES for traceability.

6. Final Packaging & Logistics

  • ESD Protection: Anti-static bags with desiccant for MSL components.
  • Cushioning: Foam inserts or vacuum-formed trays for fragile assemblies.
  • Shipping Options: Express or Economy Sea freight.
Component Obsolescence

Solution: Lifecycle monitoring, alternative sourcing suggestions, and last-time buy support.

Long Lead Times

Solution: Blanket orders with 12-month forecasts, bonded inventory, and consignment options.

Price Volatility

Solution: Price lock for 6-12 months on blanket orders and transparent pass-through pricing.

Counterfeit Components

Solution: Authorized-only policy, IQC testing (LCR + X-Ray), and full MES traceability.

Dedicated Project Manager

Every turnkey project is assigned a PM who coordinates between teams, provides weekly status reports, and flags risks immediately.
