- Quality Assurance
AEI customer applications require microwave sub-assemblies and components to perform when called upon, be it in a defense, space, or commercial atmosphere. Since its inception, it has maintained a strict adherence to the exacting standards of quality and performance, leading to fielded system application reliability. Our customers continue to repose their trust in AEI as a proven, reliable supplier.
AEI's quality system is structured to conform to a demanding program of continuous process monitoring and improvement. While not solely a function of the quality assurance department, it is company-wide in nature, affecting all disciplines: engineering, manufacturing, sales/marketing, and administration.
AEI's quality assurance system is structured in accordance with MIL-I-45208, MIL-STD-883 (including “S”), and MIL-I-38510.
AEI manufactures and qualifies products that are intended for use in equipment, conforming to MIL-E-5400 Class 2.
AEI is working toward certification to ISO 9001.
Receiving Inspection is performed on all incoming material (Electrical and Mechanical) to ensure quality and reliability, in conformance with our controlling specification and Purchase Order. In receiving Inspection of Microelectronic devices, our goal is to identify obvious and latent defects that can contribute to early- and/or long-period failure in a customer’s application. For Mechanical items, we look for visual/surface anomalies, as well dimensional features.
In-process manufacturing inspections are performed to monitor so that established production techniques are being followed and the manufacturing process can flow smoothly toward meeting the customer’s product requirements and reliability. Early detection of a deficiency allows for correction, thus enabling the product to continue its flow through the manufacturing process. An approval to continue with manufacturing is given when the in-process inspection indicates that all internal and/or customer mandated requirements are met. AEI in-process inspection is performed at the following junctures:
housing/package assembly, pre-tune, pre-cap, final assembly and test
In an effort to further ensure quality, random spot-inspections are conducted on a daily basis. AEI quality assurance personnel work closely with the Engineering; Manufacturing, Documentation, Sales and Administrative departments to guarantee that customers’ needs, and contract requirements are met.
AEI has a fully instrumented environmental testing laboratory. MIL-STD-167, MIL-STD-202, MIL-STD-750, MIL-STD-810, and MIL-STD-883 are the basis of most tests. Following is a list of commonly performed testing at AEI:

High Rel and Space Rel Screening Options
While AEI's design and construction techniques are the standard for ruggedised construction geared toward long operating life, this capability allows us to participate in the space component and subsystem markets in accordance with MIL-S-883. AEI is capable of performing most of S-level testing and screening in-house, along with the required documentation control, process tracking, and program management.
AEI performs a final quality assurance inspection prior to shipping product, in order to confirm and assure customer-required Electrical and Mechanical specification conformance in accordance with the terms of the Purchase Order. At this time, a final QA Inspection report is generated for every item to be shipped, which includes functional electrical as well as mechanical data.
