An Overview of PCB Production Quality Control Process: X-ray and Other Non-Destructive Testing Methods

In modern electronics manufacturing, quality is defined as much by what cannot be seen as by what can. As circuit boards become more compact, multilayered, and functionally dense, ensuring reliability requires more than surface-level checks. When it comes to PCB production, quality control processes are designed to verify that every layer, joint, and connection performs as intended, even when defects are hidden from view. In this article, we examine the key inspection methods used in PCB quality control. Read on to understand the role each process plays at different stages of production.
