IEC 60749-22-1:2025 provides a means for determining the strength and failure mode of a wire bonded to, and the corresponding interconnects on, a die or package bonding surface and can be performed on unencapsulated or decapsulated devices. This test method can be performed on gold alloy, copper alloy, and silver alloy thermosonic (ball and stitch) bonds made of wire ranging in diameter from 15 µm to 76 µm (0,000 6" to 0,003"); and on gold alloy, copper alloy, and aluminium alloy ultrasonic (wedge) bonds made of wire ranging in diameter from 18 µm to 600 µm (0,000 7" to 0,024").
This wire bond pull test method is destructive. It is appropriate for use in process development, process control, or quality assurance.
This test method allows for two distinct methods of pulling wires:
a) One method incorporates the use of a hook that is placed under the wire and is then pulled.
b) One method requires that after the wire be cut, a clamp is placed on the wire connected to the bond to be tested, and this clamp is used to pull the wire.
This test method does not include bond strength testing using wire bond shear testing. Wire bond shear testing is described in IEC 60749-22-2.

IEC 60749-7:2025 specifies the testing and measurement of water vapour and other gas content of the atmosphere inside a metal or ceramic hermetically sealed device. The test is used as a measure of the quality of the sealing process and to provide information about the long-term chemical stability of the atmosphere inside the package. It is applicable to semiconductor devices sealed in such a manner but generally only used for high reliability applications such as military or aerospace.
Of particular interest is the measurement of the primary sealing gases (or lack thereof), the moisture content, the presence of bombing gases that are indicative of non-hermeticity (e.g. helium), oxygen to argon ratio indicative of room air ~ 20 to 1 (± 10 %), dissimilar concentration of internally sealed gases (e.g. nitrogen, helium) than originally sealed in the device package, the presence of leak test fluid (i.e. fluorocarbon, helium, air), and all other gases to determine if the device meets the specified moisture, hermeticity and other criteria. Also of interest is the measurement of all the other gases since they reflect upon the quality of the sealing process and provide information about the long-term chemical stability of the atmosphere inside the device. The presence of leak test fluorocarbon vapour in the internal gas analysis (IGA) is an indication of failure to meet leak test requirements of IEC 60749‑8.
This test is destructive.
