The idea of operating in-circuit test as part of the surface mount technology line is not new. Options available to volume manufacturers include modifying ICT systems with bridge handlers to receive printed circuit board assemblies from the input line to the tester. Others link test units to increase throughput.
Conventional automotive electrical test methods only test each output from the electronics one by one and sequentially. This leaves a gap in the test coverage where faults, or outliers that occur simultaneously due to unexpected outputs from the electronics, are not tested or checked.
Boundary scan has been widely adopted to maintain test coverage and board quality.
The world of light-emitting diodes has seen a plethora of new applications in various devices, with vast improvements in energy efficiency, a wide range of color, longer lifecycles and so on.
Having covered the Asian test and inspection markets for over a decade, I recently made my maiden voyage to Latin America to visit in-circuit test customers for a series of users group meetings.
