Considerations of New Classes of Coatings for IPC-CC-830 Revision C
Englisch. 12 pages. Stand: Januar 2019.
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 how to add new classes of coatings to the IPC-CC-830 specification, without eliminating the historical relationship to MIL-I-46058. The new classes will be added to IPC-CC-830, Revision C.

IPC White Paper on Reliability and Washability of Smart Textile Structures – Readiness for the Market
Englisch. 20 pages. Stand: August 2018. Keine Druckberechtigung, DRM-geschützt, !!!ACHTUNG!!! NENNEN SIE BEI DER BESTELLUNG DEN USER (NAME+E-MAIL)
IPC-WP-024 is a white paper which discusses the issues associated with reliability of smart textiles (e-textiles structures) following multiple washing cycles and emphasizes efforts that industry and research laboratories must undertake to make e-textile structures more robust and able to be washed similarly to everyday textile products (e.g., underwear, clothing, home textiles and technical textiles).
The researchers provide initial reliability results of laboratory testing for e-textiles after multiple washing cycles in a commercially available washing machine and using common laundry detergents.

Guidance on Objective Evidence for Validating the Acceptability of Bubbles in Conformal Coatings
Englisch. 18 Seiten. Stand 2024.
Ion chromatography has been recognized as a method for which the data output is ion specific and very precise in the quantification of ionic residues. This paper is intended for those contemplating the setup of an ion chromatography lab and provides many of the practical considerations that should be addressed, including the core components of an ion chromatograph system such as carrier solutions, pumps, injection valves and detectors. Coverage is also given to support equipment, chemical considerations, consumables, waste streams and overall operating costs.

Guidance on Objective Evidence for Validating the Acceptability of Bubbles in Conformal Coatings
Englisch. 18 Seiten. Stand: Januar 2024
IPC-WP-028 white paper provides guidance on obtaining objective evidence for validating the acceptability of bubbles in conformal coatings. It focuses on a failure mode where bubbles in coatings could activate a microclimate involving condensation of humidity inside the bubbles resulting in an increase of the local humidity load to a critical level, thus generating electrochemical migration failures. IPC-WP-028 white paper is referenced in J-STD-001J.

IPC White Paper and Technical Report on Halogen-free Materials Uses for Printed Circuit Boards and Assemblies
Englisch. 33 pages. Stand: Sept. 2007. Keine Druckberechtigung, DRM-geschützt, !!!ACHTUNG!!! NENNEN SIE BEI DER BESTELLUNG DEN USER (NAME+E-MAIL)
In ihrem 'Weißbuch' des IPC zum Einsatz halogenfreier Materialien für Leiterplatten bekennt sich der IPC definitiv zum Einsatz der heutigen Halogenflammhemmer. In dem 29-seitigen Papier wird eine historische Bestandsaufnahme gemacht und der Status vo n Industrie- und Umweltprogrammen sowie der Gesetzeslage erstellt. Ebenso werden Informationen über Kosten, Leistungsfähigkeit, Produktzuverlässigkeit, Käufersicherheit und Lebensdauer üblicher als auch alternativer Flammhemmer, die in Leiterplatten Verwendung finden, vermittelt. Eine spezielle Arbeitsgruppe, bestehend aus unterschiedlichen Vertretern der gesamten Entstehungskette von Elektronik, erarbeitet diesen Report im Zeitraum von drei Jahren. Sie kam zu dem Ergebnis, dass sämtliche Betra chtungen und Analysen keinerlei hinweise dafür gaben, dass die jetzt eingesetzten Halogenflammhemmer irgendeine Gefahr für Umwelt und Gesundheit darstellen. Das IPC kam im Ergebnis der Untersuchungen zu dem Ergebnis, dass der Begriff Halogen-frei- le diglich ein reiner Marketing- bzw. Werbebegriff ist. Deshalb wird der IPC solange nicht von den jetzt als sicher bekannten Methoden der Realisierung der Entflammresistenz für Basismaterialien abgehen, bis irgendwann das Gegenteil, d.h. deren Schädlic hkeit genau und exakt nachgewiesen ist.

IPC/PERM-2901 (Hardcopy)
Pb-free Design and Assembly Implementation Guide
Englisch, 40 Seiten, Stand Februar 2018, Hardcopy
The European Union’s Restriction of Hazardous Substances (RoHS) legislation has had a profound impact on the electronics industry. One of the restricted substances, lead (Pb), is commonly used in alloys with tin for component finishes, printed board finishes and solders. Pb-free materials directly affect product performance, reliability and service life in many ways. There have been numerous, documented failures of electronics due to Pb-free materials in both commercial and Aerospace, Defense and High Performance (ADHP) products. Presently, there are no industry-accepted reliability models for Pb-free interconnections. The intent of IPC/PERM-2901 design guide is to assist design engineers in developing electronics that are completely Pb-free and meet the demanding requirements of ADHP systems and products. Coverage is given to Pb-free solders and solder joints, tin whiskers, printed board defects, product qualification, supply chain management, obsolescence mangement, and COTS assembly, selection and use.
