Factors to Consider When Choosing a PCB Design Company

With thousands of PCB design service vendors based in Shenzhen, narrowing down options to identify partners that best match project needs can be challenging. Here are 8 key factors to evaluate:

1. Technical Expertise and Experience

Foremost is assessing the technical competence the company brings for the type of PCB product required:

Key questions to ask:

  • How many years have they offered PCB layout services?
  • How specialized is their experience relevant to the application? (e.g. RF, analog, digital, high-speed)
  • What design tools/flows are used? And how updated are they?
  • How knowledgeable are they regarding latest techniques and technologies? (e.g. DDR4, USB 3.0)

Evaluate based on:

  • Design examples in portfolio
  • Complexity of prior projects
  • Qualifications and background of engineers
  • R&D investments in advanced capabilities

Vendors focused exclusively on PCB design services tend to accumulate greater specialized expertise versus electronics contractors diversified across multiple domains.

2. Quality Management Maturity

Reputable PCB designers adhere to quality frameworks enforcing systematic project execution and continuous improvement:

Check quality management rigor across:

  • Design processes: Established systems spanning specification analysis, architecture, documentation, analysis, reviews, change control etc.
  • Infrastructure: Usage of modern design-automation software/hardware managed under IT best-practices.
  • Materials: Parts libraries continually validated against manufacturer datasheets/updates.
  • Competency: Engineers trained and appraised on latest standards. Certification adherence demonstrates commitment.

Formal quality frameworks reduce errors and drive consistent outcomes.

3. Certifications

Most advanced PCB design firms in Shenzhen attain credentials affirming capabilities and best practices adoption:

Key certifications:

  • ISO 9001: Quality management system compliance demonstrating standardized execution.
  • ISO 13485: Rigorous guidelines for medical devices indicating enhanced reliability.
  • IPC Class 3: Benchmark knowledge certification for PCB layout engineers.
  • UL: Safety requirements conformity especially critical for high-power or consumer-facing boards.

Certificates provide added assurance although comprehensive due diligence remains essential.

4. Design Analysis Capabilities

Advanced modeling and simulation competencies differentiate PCB designers adept at predicting and enhancing complex board performance:

Key analysis areas:

  • Signal integrity: High-speed signal quality analysis via channels. Checks data loss risks.
  • Power integrity: Simulate power distribution paths. Verify voltage drops, stability across modes.
  • Thermal: Heat dissipation modeling essential for high power circuits.
  • EMI/EMC: Model electromagnetic emissions and immunity upfront to avoid external interference.

Specialist designers invest in cutting-edge solver technologies while applying methodical simulation-driven design flows.

5. Communication and Collaboration

Open channels between clients and PCB designers through each phase prevents misalignment:

Requirements gathering

  • Detailed technical discussions
  • Specification analysis

Design reviews

  • Design walkthrough and feedback

Project status

  • Scheduling alignment
  • Delay notifications

Tool preferences:

  • Digital tools (PDM/PLM) ensure real-time visibility
  • Language/culture familiarity

Overseas clients favor consistent communicators alleviating friction.

6. Documentation Discipline

Complete deliverable documentation differentiates meticulous designers:

Essential documentation:

Spec sheets: Captures board characteristics

Schematics: Visualizes connectivity

BOMs: Materials lists

Layer plots: Highlights routing

Drawings: Dimensions, tolerances, interfaces

Netlists: Components interconnectivity

Additional requirements:

  • Design workflows
  • Change logs
  • Test procedures

Clean documentation aids manufacturability, accountability, and maintenance.

7. IP Protection

For proprietary or commercial products, safeguarding intellectual property is imperative when outsourcing design:

Common protection measures:

  • NDA enforceability
  • Limited staff access
  • Secure data workflows
  • Controlled backups
  • No third party disclosures

Information shielding should cover communication, repositories, servers, premises etc.

8. Pricing Models and Engagement Flexibility

Cost structures and billing approaches vary by PCB design firm:

Common pricing models:

Fixed price: Total charges fixed upfront based on project scope

  • Time & Materials: Weekly/monthly billing based on hours logged

Full-time: Dedicated designers for multi-month engagements

Preferred attributes:

  • Flexible team ramp up/down
  • Transparent cost breakdowns
  • IP vesting provisions

Financial flexibility eases workload fluctuations and on-demand scaling.
