This standard establishes the requirements for timely customer notification of changes to electronic products and associated processes.

This standard is applicable to suppliers of, and affected customers for, electronic products and their constituent components. The goal of this notification standard is to better enable customers to manage and mitigate the disruption caused by the discontinuation of a product and to ensure continuity of supply. This standard establishes the requirements for timely customer notification of planned...

While there are a variety of industry test vehicles for the examination of material compatibility, the IPC-B-52 test board was created to meet the needs for testing both ion chromatograph and surface insulation resistance (SIR) which would be more representative of the manufacturing materials and processes. IPC-9203A standard addresses the IPC-B-52 test vehicle, which can be used to evaluate a...

The IPC-9202A, Material and Process Characterization/Qualification Test Protocol that records changes in Surface Insulation Resistance (SIR) on a representative sample of a printed circuit assembly (PCA). It quantifies any deleterious effects that might arise from solder flux or other process residues left on external surfaces after soldering, which can cause unwanted electro-chemical reactions...

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...
