Hiring An Electronic Assembly Service

Searching for a new electronic manufacturing partner can be for a variety of reasons. Some examples might include:

  • You have designs and a plan – now you need the next step.
  • You need to reverse engineer a legacy part you don’t have the files for 
  • You have an issue that your current electronic manufacturer can’t accommodate

Your next step is searching out the right manufacturer that has the certifications you need and the experience in your type of build. However, you should be searching not only for an electronic contract manufacturing service but a manufacturing partner.

Who is an OEM?

In the world of manufacturing, there are many acronyms you will familiarize yourself with. Everything begins with the OEM.

OEM SealThe OEM is the Original Equipment Manufacturer. An OEM focuses on product development and innovation in its industry. Their part design and production may be marketed or resold by another manufacturer, but the OEM will retain the rights to the part.

While some OEMs handle all aspects of electronic manufacturing, others outsource the manufacturing process to an electronics manufacturer.

An ECM (Electronic Contract Manufacturer) makes the electronic parts for the OEM. Though the parts are manufactured by the ECM, the OEM typically puts their name on the part when selling to customers.

When the OEM outsources their electronic manufacturing, they are partnering with an Electronic Manufacturing Service (EMS). AN EMS designs, manufactures, tests, ships, and repairs electronic parts and assemblies for OEMs. Some EMS partners offer product development, design assistance, supply chain management, and other valuable services.

The OEM and EMS form a true partnership through electronic component prototyping, testing, and manufacturing. This partnership adds efficiency to the product. Expert engineers are skilled in the best design and components to use. This helps streamline your material and labor costs, getting the product to market faster and at a lower cost.

Making sure your EMS manufacturer adheres to quality standards ensures that the electronic builds will meet regulatory requirements for any industry.

What is Electronic Manufacturing Services (EMS)?

An Electronic Manufacturing Services (EMS) provider is a company that designs, manufactures, tests, distributes, and provides services for the electronic components and assemblies for OEMs. Sometimes they are referred to as an ECM (Electronic Contract Manufacturer). While many EMS providers are located overseas, there are many benefits to partnering with a domestic electronic manufacturing services business. EMS manufacturers are able to offer electronic manufacturing services for high and low-volume clients, as well as components for a variety of industries.

Assembling Printed Circuit BoardSurface mount technology (SMT) on printed circuit boards (PCB) has allowed for more rapid assembly of electronics. Many OEMs found that outsourcing their PCB assembly greatly reduced their bottom line.

Previously, the electronic assembly had to be handled in-house by the electronic manufacturer. Partnering with an electronic manufacturing service allows these partners to specialize in electronic manufacturing and assembly. This frees the customer from needing to have the technology, machinery, component inventory, and expert electronic engineers.

In addition to the manufacturing, an EMS manufacturing partner can provide PCB design services, prototyping, testing, reverse engineering, and troubleshooting. Working with an electronic manufacturing partner can help ensure compliance with quality standards and regulatory requirements, as well as many additional benefits.

Why You Need On-Site Electronic Engineers at Your Electronic Manufacturer

Having on-site electronic engineers is not just an added benefit when you choose an EMS partner. An on-site engineer should be one of your main considerations when finding the right electronic manufacturing partner for your project. There are multiple benefits to choosing an outsourced EMS provider with engineering support available. An electronic device project outsourced to an EMS with on-site engineers has a much higher degree of success.

Electronic Engineer assembling productWhen an electronic engineer is involved in your project’s design and manufacturing, your turnaround time can be reduced with increased product reliability. The more expertise involved in your project, the higher the chance of success.

An on-site engineer involved in your project will look for ways to improve the quality and precision of your design. Engineers will choose components that will not add additional time and expense in the manufacturing phase.

If your project enters the manufacturing stage before potential problems are discovered, the cost of going back and troubleshooting can be expensive and add extensive time to the project.

When things go wrong, you want someone who understands your project and how to fix it before the project gets off track. Engineering support throughout the entire process means that your project has a much higher chance of success without expensive redesigns. On-site electronic engineers should be on your list of must-haves when you are choosing an electronic manufacturing partner.

Where Should You Outsource Your Electronic Manufacturing?

Choosing to outsource your electronic manufacturing is a smart decision for most OEMs. When you outsource your electronic manufacturing, you can expect expertise and efficiency with a high-functioning electronic product in return. When you are making the decision about the right electronic manufacturing partner for your product:

Delays – or worse, flawed products – can damage your reputation, but outsourcing means that you will meet all your requirements.

The benefits of outsourcing your electronic manufacturing are numerous and make a big impact on the overall scope of your project. When looking at it purely from a numbers point, outsourcing makes sense in nearly all electronic manufacturing.

Counterfeit Parts in Electronic Manufacturing

Using counterfeit parts can hurt the integrity of your electronic assemblyA counterfeit electronic component is an imitation, unauthorized, or modified electronic component that is sold and presented as a legitimate component. In some cases, it can also be a used component that has been altered to be misrepresented as new.

Counterfeit parts can be very difficult to distinguish from legitimate components, especially with those who are unfamiliar with electronic parts and components. Many suppliers who deal in counterfeit parts are able to mimic photos and packaging and have professional-looking websites. Using a counterfeit component puts your product at great risk.

Counterfeit parts are often subject to product malfunction and failure. In some circumstances, counterfeit parts can result in short circuits, electrical shocks, fires, and equipment failure. Counterfeit products can be detrimental to your company’s reputation, and they often will not work as designed.

Counterfeit parts should be avoided at all costs.

Because they can be difficult to distinguish from legitimate components, it is important to partner with an ECM that has a mitigation process, including vetted suppliers, already in place. A reliable ECM will understand how to avoid counterfeit components.

Counterfeit components have been known to slide through undetected when thorough testing is not in place. Working with an electronic manufacturer who performs thorough testing will ensure that counterfeit parts will be caught.

ECM manufacturers will know how to perform inspections and look for indents, thickness, edging, texture, and pins, which will all help in catching any potential counterfeit components.
