Residual Gas Analysis, also known as Internal Gas Analysis (IGA), is a destructive test which is performed to examine the atmosphere inside hermetically sealed devices. The test procedure is based on milling the component so that the gas content can be extracted and subsequently analyzed. The measurement of the moisture content is of particular interest as it allows to determine whether the moisture criteria are met. Also, the measurement of all the other gases might be of interest as the gas content reflects upon the quality of the sealing process and can cause long term reliability problems such as corrosion, fogging, leakage, etc.

Stress relaxation: decrease of the contact pressure held between the wires and at the wire-barrel interface, Improper crimping: neither damage the insulation of the wire strands nor to leave insulator residues over the stripped conductor. Diagnosis tools: improper degree of compression and related issues can be detected either

Microsection analysis is performed on an assembled through hole device as a part of a failure analysis. Cross-section through the plane of interest can provide helpfully information about solder defects, PCB inner layers and internal construction. As a part of a failure analysis, the plane of interest has to be selected taking into account PCB characteristic, observed failure and previous test results.
