Finding high-quality and available components can be challenging, but an EMS provider helps. These companies can select and work with reliable suppliers to ensure that the components used in your product meet your specifications. They can also negotiate better prices for parts on your behalf. Before using components in your product, EMS providers can do Component testing and validation. With some companies, it is possible to opt for inventory management and obsolescence management, to maximize the lifecycle of your components.

Testing and Quality Control

Once the assembly process is complete, an EMS provider can perform various types of testing to ensure that the product is up to par. This can include:

  • Functional testing
  • Environmental testing
  • Reliability testing

With their rigorous testing protocols and quality control processes, your provider should be able to reduce unnecessary costs.

Packaging and Shipping

Finished products must be delivered to the customer promptly and securely. To do this, the EMS may use Customized packaging. This includes options such as anti-static packaging for electronic components, foam inserts for protection during transit, and customized labeling. The provider can also offer a range of shipping options to meet your needs.

For example, they can offer standard, expedited, and even international shipping options. The providers additionally may help with customs clearance and documentation. With large providers, tracking and delivery confirmation and help with item returns and/or repair are customary.
