EMIN is pleasure to join Fluke at Booths F21 and F24 at the Vietnam International Industrial Fair (VIIF), taking place from September 9–11, 2026, at the Vietnam Exhibition Center (VEC), Dong Anh, Hanoi.

A plated through-hole (PTH) in a multilayer circuit board features a copper-plated barrel extending through the internal circuit layers; it is not merely an empty hole connecting the top and bottom layers

Through-beam sensors require two units positioned on opposite sides of the object, perfectly aligned. Many automated production lines feature mechanical gaps of only a few millimeters, leaving insufficient space for both units. In contrast, diffuse-reflective fiber-optic sensors integrate both the light emitter and receiver into a single sensing head, requiring access from only one side

A stereo microscope is suitable for visual inspection, 3D surfaces, and applications that require direct manipulation of the specimen. A metallurgical microscope is better suited to flat, prepared metal samples and applications that require high-magnification analysis of microstructures.
