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...

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...

IPC-D-620 provides design and critical process requirements for the three product classes of cable and wire harness assemblies as well as military/space applications. It is the design requirements companion to IPC/WHMA-A-620, "Requirements and Acceptance for Cable and Wire Harness Assemblies," and its associated Space Addendum Three white papers are included to provide guidance on key topics...

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...

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.

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...
