A new inspection technique helps improve the surface finish of hydraulic cylinder rods, leading to dramatically longer seal life. • Cylinder rod finish can dramatically affect seal life. • Traditional ...

Electron-beam inspection is proving to be indispensable for finding critical defects at sub-5nm dimensions. The challenge now is how to speed up the process to make it economically palatable to fabs.

In order to detect defects in the surfaces of dry fabric and composite prepreg, this new vision-based tactile sensor roller prototype, TacRoller, is a three-colour reflective membrane roller-shape ...
