ICT testing after assembly

Is there any efficient testing method for ICT testing after assembly? The surface finishing is OSP. Will this induce poor contact for the probes on the test point? What kind of test probes can we select to improve first pass yield?

Expert Panel Responses

For In-Circuit Test (ICT), an OSP finish on conventional test pads is a source of connectivity problems where test probes sometimes have trouble getting good contact. To avoid this, one consideration would be utilizing Bead Probe Technology as an alternative. More details on how bead probes can be of benefit can be found on our website.
