What's happening at ST&S Group

S T and S is delighted to announce one of our two latest acquisitions – a Fischer Technology XDV XRF.

This is in addition to our existing Fischer technology XDAL-SDD XRF. The new XDV unit has a 50 mm² SDD detector compared to the 20 mm² detector on the XDAL unit. This increase in detector size will allow for direct measurement of Phosphorus [%P] in ENIG, ENEPIG and other electroless nickel plating’s. The %P, while not overly impacting the actual performance of the nickel plating, has become an issue with some large OEMs relative to procurement requirements and the acceptable range of phosphorus present in a sample. Additionally, XRF measurements for ENIG and ENEPIG traditionally use a fixed nominal %P value in the calibration and product file. This can lead to erroneous measurement of the thickness of the nickel by understating over overstating the results based on the %P used for calibration versus the actual %P in the deposit.

Some of the additional features of the XDV:

* Premium universal XRF analyzer for automated measurements of very thin coatings (< 0.05 μm) and for fine material analysis in the sub per mil range according to ISO 3497 and ASTM B 568

* 6x changeable primary filter and 4x changeable collimators to optimize the measuring conditions

* Analysis of light elements like aluminum, silicon and phosphorus

* Sample heights up to 14 cm

* High precision, programmable XY stage with positioning accuracy of < 5 µm for automated measurements on small structures

* Detection of Pb in plastics approx. 2ppm!
