Turnkey PCBA

What is Turnkey PCBA? The Ultimate Partnership Model

Turnkey PCBA (Full Turnkey) is the most comprehensive electronics manufacturing service model. Under this arrangement, SENTAK assumes complete responsibility for the entire production process beyond providing the design files (Gerbers, BOM, Assembly Drawings). This includes sourcing all electronic components, managing the supply chain, performing PCB fabrication and assembly, conducting rigorous testing, and managing final logistics. You provide the intellectual property; we deliver a fully functional, tested product ready for integration or shipment. This model transforms us from a vendor into a true extension of your manufacturing operations, eliminating your logistical burden and mitigating supply chain risk.

Why Choose Full Turnkey? The Strategic Value Proposition

Choosing Turnkey is a strategic decision to optimize resource allocation, reduce complexity, and de-risk production.

The Turnkey Advantage vs. Consignment:

Aspect	Full Turnkey PCBA (SENTAK Managed)	Consignment/Kitted Assembly (Client Managed)
Procurement & Supply Chain	We handle it all. We leverage our volume, supplier relationships, and market intelligence to source, qualify, and manage inventory.	You handle it all. You purchase and ship all components to us, managing supplier relationships, shortages, and logistics.
Cost Predictability	Fixed per-unit assembly price. Material cost volatility and procurement overhead are our responsibility.	Variable final cost. You bear the direct cost of components and the hidden costs of procurement management.
Time-to-Market	Dramatically Accelerated. Parallel workflows: we begin sourcing immediately while engineering reviews the design.	Often Extended. Assembly cannot start until your complete kit is received and verified.
Quality & Traceability	Unified Responsibility. We guarantee the quality and authenticity of every component from our certified supply chain.	Split Responsibility. You guarantee component quality; we guarantee assembly quality.
Your Resource Focus	On Core Competencies: R&D, Marketing, Sales. Free your team from logistical tasks.	On Logistics: Purchasing, inventory management, supplier communication.

Ideal For: Startups, companies without a dedicated procurement team, projects with complex or long-lead-time components, and any organization prioritizing speed and wanting a single point of accountability.

The SENTAK Turnkey Process:A Managed,Phase-Gated Workflow

Our process is built on transparency,proactive communication,and rigorous stage-gate reviews.

Phase 1:Project Launch&Design Analysis

Kick-off:Assignment of a dedicated Program Manager and NPI Engineer.

Deep-Dive DFM/DFA: Engineering review of your design for manufacturability, testability, and cost optimization.

BOM Scrub&"Design for Procurement": We analyze every line item for availability, cost, lifecycle status, and suggest approved alternates

Phase 2:Intelligent Procurement&Supply Chain Activation

Sourcing Strategy: We utilize our multi-tiered network of franchised distributors and strategic OEM partners.

Proactive Risk Management: We identify single-source or long-lead items early, secure buffer stock, and provide regular supply chain health reports.

Component Qualification: Incoming parts undergo inspection and, if needed, electrical testing to verify authenticity and performance.

Phase 3:Manufacturing&Integrated Quality Execution

Seamless Handoff: Procurement data flows directly into our MRP system, scheduling fabrication and assembly.

In-Line Quality Gates: Automated Optical Inspection(AOI), X-Ray, and SPI ensure process control.

Your Program Manager provides scheduled build updates, including photos and data.

Phase 4:Comprehensive Validation&Delivery

Test Execution: We implement the agreed test plan—Flying Probe, ICT, Functional Test(FCT), or burn-in.

Final Audit&Reporting: Each unit receives a final check.You receive a comprehensive batch report.

Global Logistics: We manage packaging, labeling, and shipping to your specified destination.

Our Turnkey Capabilities&Technical Infrastructure

Our ability to deliver on the Turnkey promise is rooted in robust systems and deep expertise.

Supply Chain&Procurement Engine

ERP/MRP Integration: Real-time inventory and order tracking.

Preferred Partner Network: Relationships with leading distributors(e.g., Avnet, Arrow, Digi-Key)for priority allocation.

Counterfeit Mitigation Protocol: Adherence to AS6081/ISO 9001 standards, including visual inspection, XRF testing, and decapsulation for high-risk parts.

Value-Engineering&Cost Optimization

We don't just buy parts;we optimize your BOM for performance and cost.

Component Rationalization: Identifying opportunities to reduce unique part numbers.

Alternate Source Qualification: Providing equivalent, more available, or lower-cost component options for your approval.

Lifecycle Management: Flagging end-of-life(EOL)or not-recommended-for-new-design(NRND)components early.

Manufacturing&Test Scope

Full Technology Spectrum: SMT, THT, Mixed-Technology, Flex/Rigid-Flex, Box Build.

Advanced Testing: In-circuit test(ICT)fixture design, functional test(FCT)development, and automated optical inspection programming are all managed in-house.

Scalability: Dedicated production lines for prototypes and high-speed lines for volume, all under the same quality system.

Partnering with SENTAK: The Collaboration Model

A successful Turnkey partnership is collaborative,not passive.

What We Need From You:

Complete, Accurate Design Data Package: (As defined in our Prototyping Checklist).

Clear Specifications&Requirements: Target costs, quality standards(IPC Class), test expectations, and delivery schedules.

Timely Decisions: Prompt feedback on engineering change requests(ECRs)and component alternates.

What You Can Expect From Us:

A Dedicated Point of Contact: A Program Manager who owns the project's success.

Proactive, Not Reactive, Communication: Regular updates on schedule, supply chain, and any potential issues.

Financial Transparency: Clear, detailed quotations and invoices, with no hidden fees.
