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...
A discussion was held in the 5-33AWG (ad hoc working group), on things that conformal coat professionals (materials and processes) wish designers knew about conformal coating. The 5-33AWG group is comprised of individuals from OEMs, coating suppliers, and test lab personnel.
IPC-HDBK-840 supplements the solder mask requirements established in IPC specifications such as IPC-SM-840 and IPC-6012 by providing detailed information on solder mask types, application processes, pre- and post- assembly processes, characteristics and properties that are useful in the selection and use of the most appropriate mask type for a given application. Applicable to solder mask...
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...
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...

This original research was a cooperative effort between the EMPF and IPC, released as EMPF-RR-0013 in 1993 for better understanding of ionic cleanliness testing. The IPC Ionic Conductivity/Ion Chromatography Test Task Group has validated its continued importance and relevance to the cleaning community and IPC-TR-583 is the result. It includes how solvent temperature influences the final...
This single-sided (4 up) pattern is used for evaluating the interaction of solder flux and solder paste residues on printed boards. This board was used in the Phase 3 portion of the test program evaluating alternative technologies used to eliminate CFCs in printed board assembly operations. The board contains four comb patterns with 0.4 mm lines and 0.5 mm spaces. A stencil pattern is also...
