  • Optically stimulated electron emission apparatus
    Patent number: 11218111
    Abstract: An apparatus for inspecting a surface includes a housing and a probe. The housing includes a light source to direct light along a longitudinal axis and a shutter to selectively allow light to pass through to the probe. The probe includes a body portion and a head portion. The head portion of the probe includes a collector to detect photoelectrons emitted from the surface in response to light from the light source impinging on the surface. A proximal portion of the head portion moves relative to a distal portion of the head portion to allow for variations in angle relative to the surface.

  • Misinsert sensing in pick and place tooling
    Patent number: 5953812
    Abstract: The head of a pick and place system for removing IC parts from a tray and inserting them into a burn-in board (BIB) includes one or more sensors which detect light reflected from a part picked up from a tray and outputs a signal which can be analyzed to determine if the part is improperly seated in the head (misprecised) or improperly inserted into the socket of a BIB (misinserted).
