Functional Testing Strategies for Complex PCB Assemblies

As PCB assemblies increase in complexity, electrical continuity alone is not sufficient to ensure performance in real-world operation. While in circuit and flying probe testing verify connectivity and component-level integrity, they do not fully confirm that a board functions correctly within its intended application. Functional...

In Circuit Testing vs Flying Probe Testing in PCB Assembly

As PCB assemblies grow more complex, inspection alone is no longer enough to ensure functional integrity. While automated optical inspection (AOI) excels at identifying visual and placement defects, electrical testing is required to verify that circuits are built correctly and perform as intended. Two of...

AOI in PCB Assembly: Improving Yield and Catching Defects Early

As PCB assemblies become denser and more complex, inspection plays a critical role in maintaining quality and controlling cost. Automated optical inspection, commonly referred to as AOI, has become a foundational tool in modern PCB assembly by enabling early defect detection and supporting process stability....

Hand Soldering Standards and Best Practices in EMS

In modern electronics manufacturing, through-hole assembly and hand soldering are closely linked. While automation handles the majority of SMT processes, hand soldering remains essential for connectors, mechanical components, selective operations, rework, and low-volume builds. As discussed in last week’s blog on through-hole assembly, many of...

Through Hole Assembly Still Matters in Modern Electronics

Surface mount technology dominates most PCB assemblies today, but through hole assembly continues to play a critical role in modern electronics manufacturing. For many OEMs, through hole components are essential for mechanical strength, electrical performance, and long term reliability. Understanding when and why through hole...
