IEC 60068-2-69:2007 outlines test Te, solder bath wetting balance method and solder globule wetting balance method, applicable for surface mounting devices. These methods determine quantitatively the solderability of terminations on surface mounting devices. IEC 60068-2-54 is also available for surface mounting devices and should be consulted if applicable. The procedures describe the solder bath wetting balance method and the solder globule wetting balance method and are both applicable to components with metallic terminations and metallized solder pads. This standard provides the standard procedures for solder alloys containing lead (Pb) and for lead-free solder alloys. This second edition cancels and replaces the first edition published in 1995 and constitutes a technical revision. The main changes from the previous edition are as follows: - Inclusion of lead-free alloy test conditions;- Inclusion of new fluxes for testing, reflecting development of fluxes that have happened in the industry in the past 20 years;- Inclusion of new component types, and updating test parameters for the whole component list.
IEC 60068-2-69:2017 outlines test Te/Tc, the solder bath wetting balance method and the solder globule wetting balance method to determine, quantitatively, the solderability of the terminations. Data obtained by these methods are not intended to be used as absolute quantitative data for pass–fail purposes. The procedures describe the solder bath wetting balance method and the solder globule wetting balance method. They are applicable to components and printed boards with metallic terminations and metallized solder pads. This document provides the measurement procedures for solder alloys both with and without lead (Pb). This edition includes the following significant technical changes with respect to the previous edition: - integration of IEC 60068-2-54; - inclusion of tests of printed boards; - inclusion of new component types, and updating test parameters for the whole component list; - inclusion of a new gauge R & R test protocol to ensure that the respective wetting balance equipment is correctly calibrated. The contents of the corrigendum of January 2018 have been included in this copy.
