The IPC-WP-019B white paper was created to support the IPC-J-STD-001H standard and provides additional guidance, examples, and understanding of Section 8.0 Cleaning and Residue Requirements. The IPC-WP-019B has information on how to meet the requirements of IPC-J-STD-001H chapter 8. Recommentded for those looking to implement the requirements of IPC-J-STD-001H standard, chapter 8. 0..

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.

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...

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 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 document details the test procedures, test results and team conclusions for the IPC Cleaning and Cleanliness Testing Program, Phase 3, Low Solids Flux in Ambient Air. This effort has been part of a multi-stage program to investigate material and process alternatives to the use of chlorofluorocarbons (CFCs) in electronics manufacturing. This Phase 3 effort has been dedicated to characterizing...

This Technical Report details the investigations into identifying stress tests that distinguish between robust and non-robust surface finishes. A robust finish will pass a test for solderability whereas a non-robust finish will fail. The stress tests identified do not necessarily duplicate real world environment (fabrication of the bare printed board through assembly), but they must correlate to...

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...

A Technical Paper by Dr. Jack Brous discussing ionic cleanliness measurement, testing methods and cleanliness standards in relation to product reliability. Also includes a brief discussion of no-clean fluxes. 8 pages. Released 1994

Presenta también un resumen de la historia de la prueba de ROSE junto con explicaciones sobre las limitaciones de esta prueba.

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...

This document 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 technical report provides the documentation of a round robin testing effort that generated data used by the 4-14 Plating Processes Subcommittee in developing the maximum immersion silver plating thickness requirement in the revision A of IPC-4553. This compendium of data resulted from three information sets: a) Test vehicle assembly report by Celestica, b) Thermal cycle test report by...
