According to Wikipedia
Flying probe test systems are often used for only testing basic production, prototypes, and boards that present accessibility problems. Flying probe testing uses elector-mechanically controlled probes to access components on printed circuit assemblies (PCAs). Commonly used for test of analog components, analog signature analysis, and short/open circuits. They can be classified as in-circuit test (ICT) systems or as Manufacturing Defects Analyzers (MDAs). They provide an alternative to the bed-of-nails technique for contacting the components on printed circuit boards. The precision movement can probe points on PLCCs, SOICs, PGAs, SSOPs, QFPs and others, without any expensive fixturing or programming required.
While the technical definition and usage is true, the definition omits one very powerful component to using the Flying Probe test . . . that is the expertise of the test engineer conducting the test.
The Flying Probe test is the shiny object on the engineering and testing frontier. Before you engage with a company to conduct the test be sure they have the expertise to interpret results, make recommendations and use the test to create solutions.
We have all heard the phrase, “knowledge is power” yet the reality is “the proper application of knowledge is power.” The Flying Probe test is complex and requires a high level of expertise to gain results that lead to solutions. The proper application is everything . . .
