The choice of the right Electronics Manufacturing Services (EMS) provider has a significant impact on the success of your product. While you have meticulously designed your device, you are responsible for the product’s functionality. The contract manufacturer ensures that the assembly of your equipment complies with your documentation and your requirements. For this reason, the verification process of a potential EMS provider is crucial and extends far beyond the mere financial aspects of the partnership. What aspects should you consider? Read this article to learn what should be assessed.
Infrastructure and expertise
It goes without saying that the production of your specific device requires particular infrastructure and expertise. Some projects may be less demanding, while others rely on technology that only a few contract manufacturers can provide. For example, not all EMS providers can manage high-mix, low-volume production, as is supported by Poland-based Assel.
Manufacturing capacity is just one of the criteria you should evaluate. The availability of technology and methods used for coating and potting, as well as quality control measures such as AOI, ICT, X-ray, and environmental testing, is also crucial.
Manufacturing many electronic devices also involves compliance with industry-specific requirements, which must be supported by the EMS provider you choose to work with. For instance, if your equipment is designed for medical use, your contract electronics manufacturer must align their production and management practices with regulatory requirements. One of the most effective ways to verify this is by assessing relevant certifications held by the contractor, such as ISO 13485 in the case of medical devices. In addition to industry-specific requirements, your contractor must be able to comply with general electronics manufacturing standards, such as IPC Class 2 & Class 3.
Efficiency in manufacturing and supply chain management
The technology and expertise provided by your EMS provider are only part of the equation for success. Additionally, manufacturing process management is critical to ensuring the quality and consistency of the final product, maintaining business continuity, and achieving cost-efficiency.
Without thorough sourcing and procurement processes implemented by an EMS provider, Original Equipment Manufacturers (OEMs) may face production disruptions, financial losses due to oversupply of materials and components, or even faulty products resulting from the use of low-quality materials. To avoid these issues, OEMs should carefully evaluate the supply chain management practices and technologies adopted by the contract manufacturers they intend to work with.
One crucial methodology that covers both production management and certain aspects of supply chain management is Lean Manufacturing, which focuses on reducing waste and eliminating non-value-adding operations.
To assess whether a company has effectively implemented Lean Manufacturing, examine the certifications it holds. Certifications such as the industry-specific ISO 13485 for medical devices mentioned earlier, or the more general ISO 9001 for quality management systems, require the implementation of efficient manufacturing, quality control, and risk management practices, which contribute to the adoption of Lean Manufacturing. Specific Lean Manufacturing tools that a contract electronics manufacturer might implement include Poka-Yoke, 5S, CTQ, the 8D Methodology, PFMEA, and Control Plan, among others.
Communication and customer service
Smooth communication with an EMS provider is essential for effective customer service and flawless project execution. Complex electronics manufacturing projects require dedicated support from a team of qualified experts, including a program manager to guide the OEM through the manufacturing process, product engineers who can assist with cost optimisation, supply planners responsible for timely procurement, and quality assurance specialists ensuring the quality of materials, components, and final products.
Bottom line
Every aspect of contract electronics manufacturing mentioned above contributes to the success of production and cannot be overlooked. While your budget plays a crucial role in the final decision, all these factors should be considered, as underestimating any of them can lead to unnecessary costs in the long run.
