INITIAL TESTING

XRF – Analysis of termination finish

Equipment: Fischerscope XRF XDAL

Destructive?: No

Duration: PR9 10 mins – AS6081 30 mins

Description: XRF testing is primarily done to determine the RoHS status although we also confirm the exact termination finish in the process. During testing, an X-Ray beam passes through the component lead and a detector reports what elements that beam hits.

Note; For a device to be determined as RoHS it must contain less than 0.1% Lead (other elements such as Bromine and Mercury are also included in the standard). Anything greater than 0.1% is Non RoHS. As well as this, there are various lead finishes (see glossary) which can usually be confirmed against the Manufacturer’s data.
