The Quality Assurance in EEE parts is a major aspect to take care in the procurement for EEE parts. One family of EEE parts widely used are the Operational Amplifiers which are in much different equipment’s of satellites electronics
The manufacture and testing of EEE parts designed for the Space market are complex procedures that strict specification systems have ruled for years. These specifications depend on various factors such us, country of origin of the parts (USA, European, Japan…), use the parts were designed for (Space, Military) and the component’s family (resistors, capacitors, inductors, microcircuits…).
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.
The environmental conditions in the space are extreme, the combination of low pressure and the extreme temperatures can cause the failure of a component. That is why we test the components in similar conditions.
