The nozzle makes direct contact with the solder joint and is the smallest component of the desoldering tool; however, selecting the wrong diameter directly affects the lifespan of the internal pump mechanism the most expensive part to repair or replace.

On September 10, 2026, EMIN participated in an in-depth technical training program at ZEISS to update its knowledge of measurement technologies, microscopy, and quality inspection solutions for various industries, including precision engineering, automotive, electronics, aerospace, healthcare, and materials manufacturing

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
