Turn Key Assembly-About-3

About Turnkey PCB

We offer both full turnkey PCBA and partial turnkey. Both options have similar concepts – they reduce your responsibility to source electronic components, including overage calculations, managing the BOM, logistics, inventory and more.

For full turn-key services, we manage and produce everything including manufacturing the circuit boards, finding & ordering PCB components, quality inspection & testing and the final product assembly. Our technical experts apply their knowledge to each order, whether it be a low volume PCB assembly prototype project or a large scale production run.

Type of Turnkey Services

Full Turnkey

We handle the entire process, from high-quality PCB manufacturing and sourcing all necessary components, to assembly and testing—tailored to meet the specific needs of your application.

Partial Turnkey

For partial turnkey, the customer can provide the PCBs and certain components and the remaining parts are handled by RAYMING.

Consigned / Kitted Assembly

We supply all the parts, including bare printed circuit boards (PCBs) and electronic components, and assemble your boards using our state-of-the-art automated equipment for precision and efficiency.

Benefits & Cost of Turnkey Manufacturing

Turnkey PCB assembly is an outsourced service where the contractor handles the complete process of PCB production, including component procurement, assembly, programming, and testing. Unlike basic PCB fabrication or component placement, turnkey services deliver fully assembled and ready-to-use PCBs, allowing OEMs to speed up development cycles and reduce time-to-market. The article explores the benefits, reliability factors, and tips for choosing the right turnkey PCB assembly partner.

Turnkey PCB assembly offers a complete solution that streamlines the entire process, covering multiple stages:

  1. Design Support: Includes DFM analysis to optimize design for manufacturability, BOM review for cost and availability, and fabrication liaison for smooth transition to production.
  2. Supply Chain Management: Manages component procurement, vendor coordination, and inventory to ensure timely production.
  3. SMT Assembly: Involves precise solder paste printing, component mounting, reflow soldering, and quality inspection.
  4. Post-SMT Assembly: Adds protective coatings, connectors, box build, and end-of-line testing for functionality.
  5. Programming and Functional Testing: Performs in-circuit tests, boundary scan for BGA defects, firmware loading, and system functional tests.
  6. Post-Production Support: Includes repair, upgrades, warranty management, and end-of-life services.

This comprehensive approach minimizes internal engineering workloads and speeds up product introductions.

OEMs gain several advantages from partnering with turnkey assembly service providers:
 
  1. Faster time-to-market: Reduces delays in sourcing suppliers, procurement, and overcoming assembly learning curves.
  2. Improved quality: Benefit from the expertise, process capabilities, and certifications of the assembly house.
  3. Lower costs: Economies of scale from specialized assemblers lead to cost savings.
  4. Focus on core competencies: Allows internal teams to concentrate on design, engineering, and software.
  5. On-demand flexibility: Enables rapid scaling of production as needed.
  6. One-stop service: Simplifies management by dealing with a single supplier instead of coordinating multiple vendors.
  7. Proactive support: Provides design assistance, component engineering, and obsolescence mitigation.
Reliability in turnkey assembly services is ensured through several key factors:
 
  1. Stringent Quality Processes: ISO 9001 and ISO 13485 certifications establish strong quality systems.
  2. Automation: Automated inspection and assembly reduce human errors.
  3. Process Control: Statistical process control and defect tracking promote continuous improvement.
  4. ESD Control: Measures like wrist straps and ESD-safe tables prevent damage from static discharge.
  5. Cleanliness: Cleanroom environments and cleaning protocols prevent contamination.
  6. Traceability: Part serialization and date stamping allow component tracking.
  7. Testing: Comprehensive testing (e.g., ICT, boundary scan, burn-in) ensures high reliability.
State-of-the-art equipment in turnkey PCB assembly includes:
 
  1. SMT Assembly Lines: High-accuracy, multi-head chip shooters and advanced soldering processes ensure consistent and repeatable quality.
  2. Inspection: Automated optical and x-ray inspections provide superior defect detection compared to manual visual checks.
  3. Testers: Investment in test fixtures and boundary scan technology ensures comprehensive fault coverage.
  4. Materials: Reliable solder masks, solder pastes, fluxes, and underfills are selected for their durability and performance.
  5. Handling: ESD-safe hand tools, boards, and packaging materials protect components from static and physical damage.

A skilled engineering team in turnkey PCB assembly includes:

  1. Certified Engineers: IPC-certified engineers for soldering, inspection, and repair, ensuring thorough training and expertise.
  2. Experienced Technicians: Repair and rework specialists capable of quickly diagnosing and fixing issues.
  3. Subject Matter Expertise: In-depth knowledge of components allows for smart substitutions when needed.
  4. Domain Capabilities: Specialized expertise in assembly standards for industries like automotive, medical, and industrial applications.
Responsible supply chain practices in turnkey PCB assembly include:
 
  1. Qualified Suppliers: Suppliers are carefully selected and undergo regular audits to ensure reliability.
  2. Traceability: Reel-to-reel traceability in inventory and work-in-progress (WIP) ensures only quality parts are used.
  3. Counterfeit Avoidance: Parts are independently validated and tested to prevent counterfeit components.
  4. Continuity Planning: Backup sources and die banks for at-risk components prevent potential shortages.
  5. Lifecycle Management: Monitoring end-of-life notices and making last-time buys ensures continuity of component supply.
Reliable turnkey PCB assembly allows OEM engineers to reduce time spent on manufacturing coordination, enabling them to focus on product features and software innovation. By selecting the right assembly partner and engaging early in the design process, OEMs can ensure high-quality, defect-free board assemblies delivered on time. Investing in upfront Design for Manufacturability (DFM) reviews and testing validation enhances time-to-market and lowers costs related to field failures. Ultimately, turnkey assembly provides a competitive advantage by delivering well-built, durable, and advanced electronic products.
