WHAT IS THE DIFFERENCE BETWEEN AN EMS COMPANY AND ORIGINAL EQUIPMENT MANUFACTURERS?

 

 

EMS ODM OEM CEM EXPLAINED

 

 

The manufacturing industry consists of various terms being used to describe their services. EMS company, OEM, CEM, electronics contract manufacturing ECM, and ODM.

Electronic Manufacturing Services (EMS company) these are companies that offer services to design, test, manufacture for OEMs (Apple is an OEM) and offer them aftermarket service.

 

Occasionally the term electronics contract manufacturing (ECM) is also used.

 

An original equipment manufacturer or an OEM is the brand owner, and you will generally see their logo on the products. Examples would be LG, Huawei, Apple, Samsung, etc.

 

The mentioned companies all design their products ( They don’t manufacture) independently and might be outsourcing their production elsewhere to EMS companies and ODM’s. OEM’s own the rights to the product, whereas EMS companies do not.

 

Taiwan is known for ODM companies like Pegatron and Wistron, which also provide electronics manufacturing services (EMS Company).

 

A typical ODM specializes in a category of products, such as tablets, for which it offers its own designs, any are ready to manufacture it for any brand interested to put its name on. 

WHAT DOES AN ELECTRONIC MANUFACTURING SERVICES EMS COMPANY DO?

 

It varies

 

An electronic manufacturing service company (EMS company) provides different kinds of services. They bring high expertise, whether you’re in the design phase or ready to manufacture.

 

They have the individual components, the molds , the knowledge to manufacture according to your specifications in small quantities, large quantities or a high mix low volume.

 

Electronic manufacturing services also have a dedicated team for product introduction or test only operations.

 

EMS providers may have a turnkey operation or focus on PCB assembly (printed circuit board assembly) only.

 

Electronics manufacturers are often located in a different country than your company and are working with many other customers, their services are commonly divided as follows.

 

Printed Circuit Boards Assembly

 

The assembly of printed circuit boards uses either through-hole-technology (THT) or surface mount technology (SMT) to solder different parts.

 

EMS Service PCB Assembly

 

Cable Assembly

 

Custom-created cables are valuable for OEMs in many different sectors. To get the best out of this service, the electronic manufacturing services EMS provider should take care of engineering, testing, and manufacturing the product in addition to cable assemblies.

Testing 

 

  • There are different ways to test your Printed Circuit Board depending on the provider. Some of the test methods are
  •  Integrated circuits testing (ICT)
  •  Automated optical inspection (AOT)

 

Their testing capabilities might extend to different physical devices, environmental tests.

 

 

Prototyping

 

Numerous prototyping solutions depend  on the company. Some of the services are

 

  • PCB Prototyping (PCBA)
  •  Design for Procurement (cost effective)
  • 3D Printing
  • Soft tooling

WHAT SHOULD YOU LOOK FOR IN AN ELECTRONIC MANUFACTURING SERVICE COMPANY?

 

Experience

 

 Make sure to set up meetings with candidates and measure them by their manufacturing experience and how well their former projects align with what you want. Don’t be afraid to ask critical questions, and do your research about the company to determine its capabilities. 

 

How to Find The Right Partner for Your Project?

FIND OUT

 

Design Proficiency

 

Some EMS companies are very design-proficient, and others may be just electronics assembly companies, or they could be highly design-proficient in certain areas, but those areas may not be what you need for your product. 

 

International Presence

 

Having an electronics manufacturing service company with worldwide experience is vital since they understand a market’s possibilities outside of local markets.

How Technologically Advanced They Are

 

Many technologies develop rapidly. Suppose you’re trying to sell something and your electronics manufacturing services ems use older technology than your competitors. In that case, your products won’t be a match.

 

Regulatory Compliance 

 

The industry naturally has laws and regulations all electronics manufacturing services ems must comply with; making sure your ems provider complies will give you peace of mind.

 

Focused on Quality Assurance and Quality Control 

 

Having good quality assurance but not reasonable quality control means that your product is assured but not tested. 

 

If your product has reasonable quality control but no assurance, it’s tested, but the quality isn’t maintained over manufacturing and selling. 

 

A Supply Chain Management System

 

This ensures that your electronics manufacturing services ems company knows precisely how and where to find your products’ components and their lead times.

IS THE COMPANY A GOOD MATCH FOR YOU?

 

When looking for an ems partner, an easy way to eliminate possible candidates is by comparing your company’s sizes.

 

A small company compared to yours is most likely unable to meet your desired volume. Looking at how intricate their products are will also give you indications of whether they have the capabilities to become your partner.

You shouldn’t be afraid to ask critical questions regarding their production, components they use, how they integrate circuits onto a bare board engineering, supply chain, systems integration etc. talking to people in their organization will indicate what to expect and how they perceive customers.

 

TO WHAT EXTENT DO YOU WANT KNOWLEDGE OF YOUR PRODUCT’S EVERY STEP?

Some services like to reach an agreement and then let you know when they’ve completed their side of things.

 

Other services like to have more of a relationship with their clients and let you have a more significant say in areas that the services are responsible for.

 

WHAT FINANCES CAN YOU COMMIT TO THE PROCEDURE?

 

If your company is a startup and wants to keep a backup of income, it might be an idea to choose a cheaper service compared to an expensive one if any unforeseen expenses come up.

 

However, if you can’t compromise with quality, choosing the budget option might not be in your best interests. 

 

How to choose the right electronics manufacturing service

 

The services’ actual cost is not something that will be clarified at the first meeting due to many details that must be investigated.

 

However, cooperating with a capable EMS company will mean you can save money from your supply chain since you have to spend less of your resource managing them.
