STI Acquires Fischerscope X-ray XDAL 237

Estimated reading time: 1 minute

STI Electronics Inc. has acquired a new Fischerscope X-ray XDAL 237 energy dispersive X-ray fluorescence (EDXRF) system.

The Fischerscope EDXRF measuring instrument has a silicon drift detector, allowing a higher resolution for light elements, from aluminum Al (13) to uranium U (92). Not only can this system non-destructively measure various plating thicknesses on printed circuit boards and/or components, it also can measure and analyze very thin coatings (

The measurements of the plating thickness include but are not limited to the following plating stack-up combinations:

• Electroless Nickel / Immersion Gold (ENIG)
• Gold / Palladium / Nickel / Copper
• Immersion Tin / Copper
• Immersion Silver / Copper
• Tin-Lead / Copper

Mark McMeen, Vice President of Engineering Services, said, "This additional capability to perform non-destructive determination of the weight percentage of Pb (lead) and Sn (tin) in the plating accommodates the growing need for this type of testing. With both the SEM/EDS and the new EDXRF, STI’s Analytical Services Department can now better provide for customer demands."
