This guideline standard is intended to aid in interpretation of the requirements in IPC-9191, "General Guidelines for Implementation of Statistical process Control," specifically for printed board assembly (PBA) manufacture. This document and IPC-9191 should be used together; the standards are cross-referenced to each other in the Appendices of this guideline. This standard promotes process...

During mass soldering, it is important that all solder joints reach the minimum soldering (reflow) temperature to assure metallurgical bonding of the solder alloy and the base metals to be soldered. Metallurgical bonding requires that both surfaces to be soldered, as well as the solder, reach this minimum soldering temperature for a sufficient time to allow the wetting of the solder surfaces. This...

Implementing flip chip technology in a direct chip attach (DCA) assembly presents some unique challenges for design, assembly, inspection and repair personnel. IPC-7094 delivers useful and practical information to anyone who is currently using or contemplating developing products that employ the very complex and high density methods needed for the flip chip technology. The concepts have become...

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-HERMES-9852 an open industry standard, developed by The Hermes Standard Initiative and approved by IPC, provides a state-of-the-art communication protocol for machine-to-machine communication between equipment units in electronics assembly lines for surface-mount technology (SMT). Thus IPC-HERMES-9852 represents a next generation standard to the technology documented in IPC-SMEMA-9851...

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...
