Test handler head having reverse funnel design

A test head for a semiconductor device handler includes a plunger; and a funnel insert attached to the plunger via a funnel insert spring, the funnel insert having a channel extending axially therethrough, and the funnel insert including a plurality of sloped inner walls that are sloped outwardly in a distal direction of the funnel insert and configured to contact upper edges of a semiconductor device to center the semiconductor device in the funnel insert. The plunger includes a projecting portion that extends through the channel of the funnel insert. ... Delta Design Inc

Light line imager-based ic tray pocket detection system

A system for detecting a status of a pocket of a tray includes a tray having a plurality of pockets that hold an integrated circuit device, a vision mechanism, a light line generator, a reflective device, and a controller. The vision mechanism images the tray along a first optical axis. ... Delta Design Inc

Ic test site vision alignment system

A vision alignment system for a test handler system includes a transfer mechanism that transfers a device from an input side to a test side, a contactor array positioned at the test side, and a pick-and-place device that moves the device from the transfer mechanism to the contactor array. An engagement mechanism on the pick-and-place device engages with alignment devices on the transfer mechanism and contactor array. ... Delta Design Inc

Alignment mechanism

An alignment mechanism is disclosed which includes a mount, a beam having a first end affixed to the mount and a second end. The beam is an order of magnitude more rigid along its longitudinal axis than along an axis orthogonal to its longitudinal axis. ... Delta Design Inc

Ic device-in-pocket detection with angular mounted lasers and a camera

An apparatus includes a device holder including a device placement area configured to hold an electronic device, and a shoulder extending peripherally around the device placement area; a laser line generator configured to generate a laser line that includes (i) a device placement area laser line portion, and (ii) a shoulder area laser line portion; a camera configured to obtain an image of at least the laser line; and a processor configured to: receive the image from the camera, determine (i) an angle of the device placement area laser line portion, and/or (ii) an offset between the location of the device placement area laser line portion and the location of the shoulder area laser line portion, and determine whether an electronic device is positioned in the device placement area or positioned incorrectly in the device holder.. . ...
