ABSTRACT:
A hand-held surface mount pick having a handle and a bellows. The handle includes a vacuum passageway with an evacuation opening at a first end and a plurality of closely spaced vents along an intermediate region. At an end opposite to the evacuation opening is a fitting for attachment to a source of vacuum. The bellows is connected to the first end and is in fluid communication with the vacuum source via the fitting and in fluid communication with the ambient atmosphere via the vents. A protective shield is coupled to the handle at the first end. The bellows has a relaxed condition in which a portion of the bellows extends beyond the protective shield to contact an electronic component. Upon contact with the component, the vents are covered by the finger of a user, thereby creating a vacuum within the bellows to draw the component into the protective shield. In a second embodiment, the pressure differential within the bellows is created by compressing the bellows against a component, whereafter one or more vent is covered.
