IPC-WP-017 - White Paper: What Conformal Coaters Wish Designers Knew About Coatings

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, method 2.6.3.4. DWV testing was done per a modified method of IPC-TM-650, method 2.5.7.1. This paper presents the results of this blind study in coded format.
