Automated Optical Inspection (AOI)
Our AOI systems examine every solder joint and component placement on every assembly, identifying defects including insufficient solder, bridging, tombstoning, missing components, and placement errors. Automated inspection provides consistent, thorough examination that would be impossible to achieve through visual inspection alone.
X-Ray Inspection
X-ray inspection reveals solder joint quality for connections hidden from visual or optical inspection, including BGAs, QFNs, and other bottom-terminated components. Our X-ray system enables examination of voiding, bridging, and insufficient solder in these critical hidden connections.
Electrical Testing
Our electrical testing capabilities include in-circuit testing (ICT) that verifies component values and circuit connectivity, and functional testing that confirms assemblies operate as designed. Test strategies are developed collaboratively with customers to provide appropriate verification for each product.

PROCESS
The Profab Quality Control Process
Quality control at Profab Electronics follows a structured process that begins before production starts and continues through final shipment. This process ensures that quality verification occurs at the stages where it provides the most value, catching potential issues at the earliest point where they can be detected and creating documentation that supports traceability throughout the product lifecycle.
Quality control begins with incoming inspection that verifies materials meet requirements before they are released for production. Components are verified against specifications, and materials are examined for damage or contamination that could affect assembly quality. This incoming verification prevents defective materials from entering the production process where they would consume manufacturing resources and potentially affect other assemblies.
During production, in-process quality controls monitor critical operations and verify results at key stages. Solder paste inspection following stencil printing verifies paste deposits before components are placed. Post-reflow inspection — both automated optical inspection and visual examination as appropriate — identifies any assembly defects before additional processing occurs. For assemblies requiring multiple process steps, inspection occurs at stages where defects can be identified and addressed most efficiently.
Final inspection and testing provide the ultimate verification that assemblies meet all requirements before shipment. The specific inspection and test content varies based on product requirements, customer specifications, and industry standards, but always provides appropriate verification that assemblies are ready for their intended application. Following successful inspection and test, assemblies are packaged appropriately for shipment, completing the quality control process.
QUALITY ASSURANCE
Our Commitment to Quality Excellence
Quality at Profab Electronics represents more than a department or a set of procedures — it is a fundamental commitment that drives our entire organization. This commitment begins with leadership that prioritizes quality in every decision and extends throughout our organization to every team member who understands their role in delivering quality products. Our quality commitment is demonstrated not through slogans but through the investments we make in capable processes, the training we provide to our team, and the results we deliver to our customers.
