Calibration Standards for Lead Frames

XRF Standards

Bowman supplies reference standards for precisely calibrating any XRF coating thickness and elemental analysis system.

We provide single and multi-layer foils, as well as hard-plated standards in every common thickness, for aluminum, cadmium, chromium, cobalt, copper, gold, iron, indium, lead, nickel and electroless nickel, palladium, platinum, rhodium, silver, tantalum, tin, titanium, and zinc.

Bowman supplies single and multi-layer foils and hard-plated standards for all XRF equipment and applications.
