There are three ways that major industries use to calculate Printed Board Assemblies Manufacturing Test Coverage. The problem with these methods is that they combine parameters that are either relative to inspection or testing to provide an overall Test Coverage. This may lead to misinformation and making wrong decisions such as removing inspection or test steps due to complacency with Test Coverage results. A survey was performed to understand better which method is being used and the needs the users have. To generate a new method of calculating the Printed Assemblies Board Manufacturing Test Coverage, the results were analyzed, requirements were established, and a new method was designed. A way to test this method needs to be generated using the Printed Board Assembly Complexity Index. Key Terms ⎯ Electrical Testing, Inspection, Printed Board Assemblies, Test Coverage.
