Key Insight: IEC 61188 is the international standard family governing the design and use of printed boards (PCBs) and printed board assemblies (PCBAs). Its core document, IEC 61188-5-1, is technically identical to IPC-7351B and defines a rigorous mathematical model for…
📅 Standard Series: IEC 61189 (Parts 1–6, Active) | 🏷️ Category: PCB & Electronics Assembly Test Methods | 📖 Reading Time: 12 min If you design, manufacture, or qualify printed circuit boards and electronic assemblies, IEC 61189 is the definitive…
Standard Overview IEC 61190 is the cornerstone materials standard for electronic assembly, comprising two parts: Part 1 (IEC 61190-1) specifies classification and requirements for soldering fluxes, while Part 2 (IEC 61190-2) defines technical specifications for solder pastes. Together, they provide…
Standard Overview: IEC 61191 is the definitive international standard governing quality and workmanship for soldered electronic assemblies. Published by the International Electrotechnical Commission, this multi-part standard establishes acceptance criteria for solder joints, component placement accuracy, assembly cleanliness, and inspection methodologies…
The transition from electronic design to manufacturing has long been fraught with data translation issues, format incompatibilities, and manual re-entry errors. IEC 61182 directly addresses this challenge by defining a standardized XML-based data format for transferring printed board assembly information…
Every sound level meter measures sound pressure — but the relationship between the pressure at the microphone diaphragm and the true sound pressure in the undisturbed field depends heavily on the type of acoustic environment in which the measurement takes…
