Turnkey PCB Assembly (PCBA) Services Usage Strategies

The electronics manufacturing industry is undergoing rapid and dynamic changes, encompassing both product iterations and structural transformations. Within the modern electronics manufacturing landscape, there is a notable decline in the proportion of manufacturing and trade companies, as more organizations are opting for PCB assembly services. Among these services, turnkey PCBA has gained significant popularity. So, what sets turnkey PCB assembly apart and why is it so favored? Furthermore, when should this service be utilized?

Learn About Turnkey PCB Assembly

What is turnkey​

In PCBA projects, the term “turnkey” or one-stop refers to a comprehensive and integrated service model, which is often referred to as Electronics Manufacturing Services (EMS). When engaging in turnkey PCB assembly solutions, the manufacturer or fabricator assumes the responsibility of understanding the complete requirements of your project and endeavors to accomplish it with utmost excellence. As a customer, your role primarily involves project acceptance. Essentially, the manufacturer assumes accountability for all facets of the design, procurement, manufacturing, assembly, testing, packaging, and other relevant aspects of the electronics project, enabling you to focus solely on product marketing and sales.

What is partial turnkey

A comprehensive electronics project commences with the fabrication of bare boards, which entails the addition of components to realize a fully functional PCBA board. The term “part” in this context signifies the method by which these components are sourced. In a partial turnkey PCB assembly, the manufacturer assumes responsibility for procuring a portion of the components, while the customer supplies the remaining components.

What necessitates such an arrangement?

To begin with, PCBA companies primarily specialize in manufacturing and processing, rather than component production. Consequently, they act as intermediaries for component sourcing, and they may incur additional costs for proprietary or high-priced components that are not cost-effective. Moreover, electronics manufacturers may have surplus component inventories, which can be effectively managed through partial turnkey services.

How turnkey PCBA projects are conducted

Phase 1 - PCB to PCBA Prototyping

Prototyping is an essential step in the early stages of a project or collaboration to validate design feasibility and assess the manufacturer’s service quality. Some online quotation companies may offer competitive prices and rapid turnaround by consolidating PCB from different projects to achieve cost efficiency.

Phase 2 - Low Volume Production

While the unit price may be higher, low volume production is generally considered worthwhile. For small companies, small batch production alleviates liquidity pressures, enabling them to allocate resources towards system upgrades and product promotion, leading to increased profits. It accelerates the return on investment for subsequent small batch production. Moreover, it mitigates inventory challenges and reduces various risk factors faced by companies.

For large companies, small batch production facilitates market response assessment. Introducing a new product without fully understanding its feasibility requires a market trial. Small batches, consisting of a few hundred or thousand units, allow for market release, observation of consumer reactions, design optimization, and clear guidelines for subsequent mass production feasibility.

Phase 3 - Mass Production

One of the key advantages of utilizing full turn key PCB assembly is the competence and reliability of the service providers offering this solution. Turnkey implies that the manufacturer possesses all the necessary production resources, from manufacturing to assembly, which demands a significant investment. Notably, establishing an SMT production line alone typically entails an investment of at least $500,000. As the business expands, the demand for PCBA boards from electronics manufacturers continually increases, necessitating the manufacturer to possess sufficient capacity to execute mass production during the third phase.

Phase 4 - Inventory Management

Throughout the procurement stage and post-production, careful attention is given to the service provider’s warehouse management capabilities. Due to production complexity or specific reasons, certain boards or components may not be immediately utilized in electronic devices. Therefore, adequate storage space becomes crucial. Engaging in turnkey services offers a solution for inventory management, eliminating the need for the customer to rent or oversee inventory independently, as these responsibilities are handled by the manufacturer.

Do You Need a Full Turnkey PCB Assembly Service

Advantages

  • Enhanced project management: Eliminates the need to coordinate and communicate with multiple manufacturers simultaneously, minimizing management oversights and ensuring effective communication throughout the project management process.
  • Accelerated turnaround time: By consolidating services under a single provider, the time spent searching for multiple service providers is significantly reduced. Additionally, the elimination of separate board shipments leads to faster turnaround times in electronic projects.
  • Cost efficiency: Reduce costs during shipping while avoiding the use of high cost components by utilizing component replacement services in turnkey services to reduce the overall cost of the project.
  • Superior quality: Avoids the potential failure rate issues of boards in transit thus improving PCBA manufacturing quality.
  • Versatility: Professional one stop PCB assembly services cater to a wide range of requirements, whether it involves prototypes, SMT, THT, BGA, or other assembly techniques.

Disadvantages

  • Cost implications: Engaging a PCB assembly company to handle component sourcing naturally incurs additional costs, leading to higher service fees.
  • Dependency concerns: Relying heavily on turnkey services can result in dependence on manufacturers, potentially limiting the diversification of the supply chain and hindering the company’s ability to innovate.
  • Control dynamics: Entrusting the project to a manufacturer in a turnkey arrangement means relinquishing some control.
  • Confidentiality risks: Utilizing turnkey services entails sharing comprehensive design files and technical details with the manufacturer, which may pose a risk if dealing with unscrupulous manufacturers who could potentially compromise the confidentiality of sensitive information.

When to use PCB turnkey solutions

In the realm of PCBA, it is crucial to acknowledge that nothing is absolute, and every approach has its pros and cons. Therefore, it is wise to develop a cooperative strategy based on the company’s development. The question then arises: When should turnkey PCB services be utilized? TechSparks offers the following insights:

Understanding your business is paramount. What is the nature of your business? What are its core strengths? What are your goals and objectives?

For startups, turnkey can be a suitable choice. These companies often face financial constraints and seek to avoid storage fees. Moreover, startups often struggle with limited manpower. Opting for a turnkey project enables them to leverage the expertise of external professionals, such as designers, who can provide invaluable support.

Every company has its strengths and weaknesses. Some organizations excel in research and development, while others thrive in marketing. Turnkey services can greatly benefit marketing-oriented companies. By delegating design and R&D tasks to specialized professionals, companies can focus on maximizing their strengths in marketing.

Brokers are strongly advised to collaborate with turnkey PCBA companies. The PCBA industry contains a mix of players, and online brokers claiming to be manufacturers are prevalent. However, when asked for a quote, these brokers often scramble to find the actual manufacturer. To navigate this landscape effectively, brokers are wise to partner with reputable turnkey service providers, ensuring a streamlined and reliable supply chain.
