This part of IEC 60749 provides a test method that is intended to evaluate and compare drop
performance of surface mount electronic components for handheld electronic product
applications in an accelerated test environment, where excessive flexure of a circuit board
causes product failure. The purpose is to standardize the test board and test methodology to
provide a reproducible assessment of the drop test performance of surface-mounted
components while producing the same failure modes normally observed during product level
test.
This document aims at prescribing a standardized test method and reporting procedure. This is
not a component qualification test and is not meant to replace any system level drop test that
is sometimes used to qualify a specific handheld electronic product. The standard is not meant
to cover the drop test required to simulate shipping and handling-related shock of electronic
components or PCB assemblies. These requirements are already addressed in test methods
such as IEC 60749-10. The method is applicable to both area array and perimeter-leaded
surface mounted packages.
This test method uses an accelerometer to measure the mechanical shock duration and
magnitude applied which is proportional to the stress on a given component mounted on a
standard board. The test method described in IEC 60749-40 uses strain gauge to measure the
strain and strain rate of a board in the vicinity of a component. The customer specification states
which test method is to be used.

This part of IEC 60749 establishes the procedure for testing, evaluating, and classifying devices and microcircuits according to their susceptibility (sensitivity) to damage or degradation by exposure to a defined field-induced charged device model (CDM) electrostatic discharge (ESD).
All packaged semiconductor devices, thin film circuits, surface acoustic wave (SAW) devices, opto-electronic devices, hybrid integrated circuits (HICs), and multi-chip modules (MCMs) containing any of these devices are to be evaluated according to this document. To perform the tests, the devices are assembled into a package similar to that expected in the final application.
This CDM document does not apply to socketed discharge model testers. This document describes the field-induced (FI) method. An alternative, the direct contact (DC) method, is described in Annex J.
The purpose of this document is to establish a test method that will replicate CDM failures and provide reliable, repeatable CDM ESD test results from tester to tester, regardless of device type. Repeatable data will allow accurate classifications and comparisons of CDM ESD sensitivity levels.

In general, dynamic ON-resistance testing is a measure of charge trapping phenomena in GaN power transistors. This publication describes the guidelines for testing dynamic ON-resistance of GaN lateral power transistor solutions. The test methods can be applied to the following:
a) GaN enhancement and depletion-mode discrete power devices [1]
b) GaN integrated power solutions
c) the above in wafer and package levels
Wafer level tests are recommended to minimize parasitic effects when performing high precision measurements. For package level tests, the impact of package thermal characteristics should be considered so as to minimize any device under test (DUT) self-heating implications.
The prescribed test methods may be used for device characterization, production testing, reliability evaluations and application assessments of GaN power conversion devices. This document is not intended to cover the underlying mechanisms of dynamic ON-resistance and its symbolic representation for product specifications.

IEC 60747-5-14:2022(E) specifies the measuring method of the surface temperature of single LED die or package, based on the thermoreflectance (TR) method. TR is the effect that the reflectance of light changes with the temperature of a substance. This part measures relative change in the reflectance of light from a metal film deposited nearby on the metallurgical pn junction as the relative change in the LED junction temperature. The surface temperature can be approximated as the junction temperature when the thermal resistance effect between the metal surface and the pn junction is negligibly small.
