SonoLab welcomes X-ray tool

12 th International Tube and Pipe Trade Fair for Southeast Asia

AS part of Nordson’s acquisition of Sonoscan, a Nordson DAGE X-ray tool was recently added to the C-SAM ® acoustic micro-imaging tools available at Nordson Sonoscan. Ultrasound penetrates most production materials, including dense metals, but not air or porous materials. X-ray penetrates air and porous materials in addition to most production materials, but may not penetrate some dense metal layers. X-ray images are created by transmitting X-rays through the sample and detecting the shadow image it casts. Higher density materials such as solder cast a darker shadow, while lower density regions such as voids cast a lighter shadow, making it easy to see features such as voiding. Scattering of X-rays is typically not observed. Ultrasound is partly reflected and partly transmitted at interfaces between most materials, but is almost entirely reflected by the air-to-solid interface at voids and other gaps, and there is no transmission, even if the void or gap is only a fraction of a micron thick. This property of ultrasound makes imaging thin delaminations easy, even in samples containing dense metals. The wires in devices scatter ultrasound and make imaging difficult, but X-ray’s higher resolution brings out the details. The ability to move samples between the two side-by-side and complementary non-destructive tools has already demonstrated superior results for SonoLab customers, the company reports.
