The IPC-9701B standard establishes a thermal cycling test method to characterize the fatigue lifetimes of surface mount solder attachments of electronic assemblies. The surface mount devices may be solder-attached to rigid, flexible or rigid-flex printed boards. The characterization results can be used to predict the field lifetime of solder attachments for the use environments and conditions of...

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...

The IPC-9709A standard guideline document establishes an Acoustic Emission (AE) method to enhance evaluation of the performance and reliability of surface mount attachments of electronic assemblies during mechanical loading.

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...

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...
