The cost of manufacturing printed circuit board assemblies (PCBAs) has always been a concern for original equipment manufacturers (OEM) and contract manufacturers (CM). This is one of the reasons why ...

Boundary scan offers clear advantages over technologies that require physical contact with a unit under test. It is also useful for ferreting out faults among the expensive, advanced semiconductor ...

Boundary scan, based on IEEE Standard 1149.1 and related specifications, has become widely used to solve difficult test problems on complex PCBs. The difficulties arise due to lack of access needed by ...

Despite its standardization as IEEE 1149.1 in 1990 and wide use in the industry, many test engineers and developers still do not fully understand the benefits of boundary scan test. The misconceptions ...
