Critical Factors in Selecting an EMS Company for Aerospace Products


By Mo Ohady, General Manager, Digicom Electronics


quality manufacturing processes. For aerospace applications, where re- quirements are stringent and device failure is not an option, choosing an EMS partner is critical. Knowledge of an EMS company’s certifications and processes, along with facilities, serv- ice and support, can lead to success when selecting an EMS company.

Certifications When manufacturing aerospace


products, the first thing to check is the EMS provider’s quality certifica- tions. Having received a quality cer- tification says a lot about a company. The certification required for aero- space quality manufacturing is AS9100. It has recently been revised to AS9100:2016 (Rev D). AS9100: 2016 (Rev D) standardizes quality management system requirements for organizations that design and manufacture products for the aero- space industry, including parts, com- ponents and assemblies. The standard is prepared by the


International Aerospace Quality Group (IAQG), with representatives from aviation, space and defense companies in the Americas, Europe and Asia. The Society of Aerospace

indicate that a company has a quali- ty management system. It involves much more. It involves top manage- ment’s commitment and leadership to define their strategic business vi- sion as it is influenced by the inter- ested party’s requirements,” says Douglas Sutherland, president and CEO of NeXsys Group, Inc., a profes- sional services company that assists others in achieving AS9100 and ISO certifications. “Achieving certification shows


that a company is dedicated to carry- ing out an efficient and productive business process management sys- tem. Especially for an EMS company, it demonstrates that they have a de- sign and development process for how to build something and a methodology to weed out and miti- gate potential problems or failures.”

the enre board, and this causes a new set of adverse consequences. Process engineers were forced to magnify one problem to solve the other and create a mess in the process.


InterFlux ICSF-Select is an Intelligent Fluxer. It gives process engineers the freedom to independently tailor the volume, pressure, and locaon of flux jeed at each joint. They can add more flux for increased acvity or more pressure for deeper penetraon. The flux is only applied where needed and does not migrate where it is unwanted. Improved quality and less mess – problems solved!
