A template for developing a Foreign Object Debris (FOD) Control...

This technical paper covers the testing and evaluation of polymeric conformal coatings for moisture and insulation resistance (MIR) and dielectric withstanding voltage (DWV). This effort was initiated by the IPC Conformal Coating Task Group to support technical decisions for IPC coating specification CC-830 as part of the Revision C process. MIR testing was done per a modified method of IPC-TM-650...

Lead-free electronics continues to be a concern of the aerospace, defense, and high performance products (ADHP) industries. This is primarily due to the lack of data and knowledge to: thoroughly categorize performance under harsh service conditions and provide a level of confidence in reliability assessments of Pb-free electronics equal to those for traditional tin-lead electronics. To help close...

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...

Due to a concern in the electronic packaging industry about solderability problems, Foster Gray, PC Interconnects, developed this document for the Surface Mount Council. Areas covered are: design for the soldering process; solderable PWBs; solderable components and soldering process. Five different industry perspectives provide analysis of these issues. 35 pages. Released August 1991.

Status of the technology discussion on the various methodologies for mounting and interconnecting active devices to a variety of substrate materials is summarized in this document. Reviews mounting techniques of tape automated bonding (TAB), chip on board (COB) and flip chip. Examinations of the most commonly used substrate options of laminate, ceramic and silicon are also reviewed. Editor: John...

The IPC-WP-026 white paper explores blockchain as an emerging technology that has a core strength in providing an immutable, auditable, transparent and secure environment for data exchanges. These advantages make it a prime candidate for implementation in the electronics industry. The IPC-WP-026 white paper explores blockchain and its limitations and challenges. It also provides a few directions...

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...

The PERM Lead-Free Manhattan Project (LFMP) was established to identify the technology and knowledge gaps relevant to the implementation of commercially available Pb-free product in Aerospace & Defense Systems. These knowledge gaps threaten to affect the safety, performance and reliability of Aerospace & Defense systems, which cannot be compromised. Investment is required to close these knowledge...

The problem of counterfeit components continues to escalate. It is no longer limited to high value items like semiconductors. It can include connectors, resistors, passive components or anything that is in demand. What more could you be doing to ensure that the components you purchase are genuine? What can you do about component traceability? Jack Stradley, Manager, Business Development &...

The IPC Solder Products Value Council’s Technical Subcommittee Report “Take Action Limits (TAL) for SAC305 Lead Free Soldering Processes Utilizing Solder Baths/Pots” reports on research on take action limits of solder pot contamination for SAC305 lead-free solder. As opposed to one maximum contamination level, the IPC SPVC opted to identify three action levels: Normal operation defined as the...

IPC-WP-019A a revised white paper provides an overview of ionic cleanliness requirements, providing examples of tests and requirements for acceptability from a residue/cleanliness standpoint. The history of ROSE testing is also provided, with explanations of the shortcomings of that testing.

This addendum to J-STD-001, originally developed for Revision B but also applicable to Revision C, proposes solutions for cost-effective testing and increased implementation. Also covers other assembly test methods that are not addressed in J-STD-001. 12 pages. Released October 1996. Now available in electronic format.

Details the results of a two-year study to determine the effect of steam aging exposure on components. A variety of solderable finishes were used. A small production simulation utilized preconditioned and as-received samples and tested a total of 2,000 joints. 15 pages. Released July 1996.

IPC-TR-587 technical report delivers results of a major study on conformal coating. In most manufacturing specifications, conformal coating thickness is defined as the thickness of the final polymer film on a flat, unencumbered surface of the assembly, however conformal coating thickness on other assembly and component surfaces is not characterized. IPC-TR-587 is a report outlining an IPC study of...
