The IPC-5262 prescribes the minimum design, critical process and acceptance requirements for the application of polymeric materials to electrical/electronic components, modules, printed wiring assemblies and other elements thereof. The intent of IPC-5262 is to establish a baseline of requirements, procedures, practices and process attributes based on lessons learned and best practices that have...

Every electronics manufacturer, whether an original equipment manufacturer (OEM) or electronics manufacturing services (EMS) company, must determine if the unpopulated printed boards entering the assembly process have an adequate level of cleanliness. The question of “how clean is clean enough?” is one that has no definitive answer, as there is no "golden number" for board cleanliness. The issue...

Tackling PCB cleanliness is a tough job; residues on printed circuit boards are directly related to the reliability of the produced hardware and can result in serious failures if not known or monitored. But how do you measure "cleanliness"? How clean is "clean"? The IPC-5701 provides guidance into how these issues should be approached and specified in purchasing documents, addressing levels of...

This standard is intended as a guideline in the proper preparation of a metallographic sample (microsection) of a printed board. The finished microsection is used for evaluating the quality of the laminate system and plated structures (e.g. PTHs and vias). Microsection sample preparation is regarded by many as a highly developed skill. The guidelines in this standard discuss the many variables and...

The European Union’s Restriction of Hazardous Substances (RoHS) legislation has had a profound impact on the electronics industry.
