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...

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...

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...

IPC-2292 standard establishes specific requirements for the design of printed electronic applications and their forms of component mounting and interconnecting structures on flexible substrates. Flexible substrates, as pertaining to IPC-2292 standard, are materials or devices which have some amount of flexibility or bendability (not rigid) but are not considered to be stretchable (e.g., fabrics...

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...
