Printed Circuit Board Assembly and Test

Printed Circuit Board Assembly and Test Description:

Printed circuit board assembly (PCBA) is one of our core services Vexos. From multi-layered to flexible printed circuit boards, Vexos is your one-stop shop for printed circuit board assembly, testing, and commodity sourcing of boards and other material services. We provide our customers with PCB fabrication solutions and services worldwide, from design to delivery.

Our global manufacturing facilities are fully equipped with state-of-the-art testing and verification equipment. Finished PCB Assemblies are checked for proper component placement and functionality with a variety of methods including AOI Inspection, In-Circuit Testing, and X-Ray inspection.

ICT AND FUNCTIONAL PCBA TESTING ENSURE PCB ASSEMBLY QUALITY

Vexos is highly process-focused with adherence to J-STD-001 standards. All PCB assemblies are verified for part-placement accuracy; the use of critical checks such as signal integrity, functionality and performance to test specifications are fully incorporated into our PCBA testing procedures.  Comprehensive PCBA testing capabilities include functional PCBA testing equipment and in-circuit testing (ICT).

​​

PCBA TESTING WITH MULTI-STEP VERIFICATION

To ensure the highest quality, Vexos provides functional testing and in-circuit testing (ICT) services. Our test technicians and quality engineers are highly skilled, well-trained and will assemble and inspect to IPC-610 and J-STD-001 standards. Our manufacturing facilities and printed circuit board assembly processes have been audited and certified to these standards.​

Once a PCBA is fitted with all necessary components and passed through the SMT assembly line, it is verified for compliance with customer CAD data using an inline AOI machine. Boards with bottom terminated components will go through x-ray inspection to ensure part-placement accuracy. Each assembly may then be subjected to in-circuit testing and/or functionally tested to customer specifications by a dedicated staff of test technicians.​

The functional test stands used in the above process can be as simple as a set of electronic measuring devices on a workbench or as complex as a six-foot, rack-mounted, integrated testing system. While many customers choose to provide functional test equipment, Vexos engineering staff has full capabilities to design and build customized functional testing systems.
