This standard on spherical transient bend testing is intended to characterize the maximum allowable strain that a surface mount component's board level interconnects can withstand in flexural loading. Whereas four-point monotonic bend test methods only address simple planar bending, spherical bend tests establish strain limits of board level interconnects under worst-case flexure conditions that...

The IPC-WP-021 white paper considers conformal coatings, like many high-performance materials, have evolved considerably since the 1990s. New coatings, such as fluoropolymers or hybrid coatings, have come on the market, many of which offer superior protection characteristics, but do not fit into the existing classifications of either MIL-I-46058 or IPC-CC-830. The IPC-WP-021 white paper discusses...

IPC-9631 addresses concerns and considerations related to IPC-TM-650, Method 2.6.27, Thermal Stress, Convection Reflow Assembly Simulation. This document describes how the test method is intended for use and the rationale behind some of the protocols and requirements. This document was developed with the understanding that the test method will require special equipment and the proper set-up and...

Establishes mechanical drop and shock and test guidelines for assessing solder joint reliability of printed board assemblies from system to component level. This document addresses methods to define mechanical shock use-conditions, methods to define system level, system printed board level and component test board level testing that correlate to such use conditions and guidance on the use of...

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...

IPC/WHMA-A-620E-RL is a redline document showing the difference from IPC/WHMA-A-620D to IPC/WHMA-A-620E. IPC/WHMA-A-620E-RL provides a side-by-side comparison of the two documents and includes the figures and tables. The document shows deleted/changed text in the IPC/WHMA-A-620D pages and new/revised text in the IPC/WHMA-A-620E pages. Due to the complexity of this document, it is only available in...

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...
