1 Scope
This part of IEC 60749 establishes a standard procedure for determining the solderability of device package
terminations that are intended to be joined to another surface using tin-lead (SnPb)
or lead-free (Pb-free) solder for the attachment.
This test method provides a procedure for ‘dip and look’ solderability testing of
through hole, axial and surface mount devices (SMDs) as well as an optional procedure
for a board mounting solderability test for SMDs for the purpose of allowing simulation
of the soldering process to be used in the device application. The test method also
provides optional conditions for ageing.
This test is considered destructive unless otherwise detailed in the relevant specification.
NOTE 1 This test method is in general accord with IEC 60068, but due to specific requirements of semiconductors, the following text is applied.
NOTE 2 This test method does not assess the effect of thermal stresses which may occur during
the soldering process. Reference should be made IEC 60749‑15 or IEC 60749‑20.
