IEC 60068-2-69:2017

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 60068-2-54:2006 outlines Test Ta, solder bath wetting balance method applicable for any shape of component terminations to determine the solderability. It is especially suitable for reference testing and for components that cannot be quantitatively tested by other methods. For surface mounting devices (SMD), IEC 60068-2-69 should be applied if it is suitable. 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 1985 and constitutes a technical revision. The major technical changes with regard to the previous edition concern: - the addition of lead free solder alloy (see Clause 7, Materials); - reversal of force-time curves to align with IEC 60068-2-69 (see Figure 2 and Figure B.1); - modification to the test requirement for progress of wetting (see Clause 9).
