As most of the world converts to lead-free manufacturing, the concern over tin whiskers as a reliability hazard has grown due to the emergence of pure tin as a dominate component surface finish. A significant amount of research on tin whisker formation and tin whisker mitigating strategies has been performed in both commercial and defense industries. This working paper is a summary of the...

This handbook is a companion reference to J-STD-001, Requirements for Soldered Electrical and Electronic Assemblies. The intent of the Handbook is to provide supporting information for the Standard, explain the "how-to" and "why" behind the criteria and provide the fundamentals for the processes to make acceptable soldered connections.

This handbook is a companion reference to J-STD-001, Requirements for Soldered Electrical and Electronic Assemblies. It describes materials, methods, and verification criteria that, when applied as recommended or required, will produce quality soldered electrical and electronic assemblies. The intent of the Handbook is to explain the ‘‘how-to,’’ the ‘‘why,’’ and fundamentals for these processes...

IPC-A-610 Revision E to Revision F Redline Comparison Document. This document is free to Task Group members participating in development of the standard and to Certification Centers with current training licenses for the associated Training and Certification program. CITs who are not members of the Task Group are encouraged to contact his or her MIT for a copy of the redline document.

This document provides tests that record changes in surface insulation resistance (SIR) on a representative sample of a printed circuit assembly. 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 electrochemical reactions that grossly affect reliability. It uses test vehicles that...

Surface mount pad cratering typically initiates prior to detection by existing electrical monitoring test methods. There are limited instrumentation techniques that are currently available that can identify non-electrical damage and its location to a high degree of accuracy. This guideline document establishes an acoustic emission (AE) method to evaluate the performance and reliability of surface...

While there are a variety of industry test vehicles for the examination of materials compatibility, most available test boards leave something to be desired as there is often a dramatic difference in materials between such test boards and produced assemblies. A test vehicle was needed which could be used for both ion chromatography and SIR testing that would be more representative of mainstream...

Cleaning of stencils and misprinted PCBs has taken an increasingly important role in surface mount technology. Fine and ultra-fine pitch lands, together with other advanced packages, place new demands on stencil cleaning. Paste volume is a critical issue for fine, ultra-fine, chip-scale, BGA and flip-chip components. Insufficient solder due to clogging of stencil apertures is a primary cause of...

This standard describes the design and assembly challenges for implementing Bottom Termination surface mount Components (BTCs) whose external connections consist of metallized terminals that are an integral part of the component body. The BTCs in this document include all types and forms of bottom-only termination components intended for surface mounting. This includes such industry descriptive...

The IPC-7091 intends to provide useful and practical information to those who are designing, developing or using 3D-packaged semiconductor components or those who are considering 3D package implementation. The 3D semiconductor package may include multiple die elements—some homogeneous and some heterogeneous. The package may also include several discrete passive SMT devices, some of which are...

This peer assessment provides a baseline understanding of e-textile process techniques, requirements and resources within this emerging sector.

Manufacturers of high reliability electronics have been working for many years to mitigate the deleterious effects of tin whisker formation. One highly effective means to suppress the growth of tin whiskers is to replace the pure tin plating with reflowed tin-lead solder. One approach is to fully consume the tin plating by tin-lead solder during the SMT reflow process. This phenomenon of tin...
