Thinking Beyond a Single Platform In Circuit Strategy
Big iron in circuit testers have been sold for years as a “does everything” platform: analog in circuit; digital vector (backdrive) test, vectorless test, ISP programming, boundary scan, instrumentation-based functional test, etc.
Unifying all these tasks promises to simplify and standardize the test group’s task, no matter what unexpected new technologies product designers may send their way. There’s no additional equipment to justify to management and to buy. The staff is already trained in using the system. The big iron tester vendor says, “Just add some optional hardware and software, and you’re ready to go.”
But reality is always more complicated.
The Two-Stage In Circuit Board Test Strategy
At first, it seems counterintuitive, but implementing new tests on a new, low cost platform can drastically simplify the overall task, speed throughput and cost far less than trying to integrate everything on your big iron tester. How?
