Aries Chip Scale Test Sockets: Spring Probes, Data Sheets, & Test Reports
Shows Spring Probes, top and bottom, typical of the Aries Clamshell type test socket family.
( Shown above: Test socket for 14mm to 27mm sq devices, Data sheet 23018)
The family of Aries Clamshell style test sockets consist of four standard sizes of sockets each accommodating a wide range of devices. The socket is screwed to the board with four screws. Electrical contact is by way of pressure spring probes. The sockets are designed to be modified to work with BGAs or LGAs or just about any other type of SMT device regardless of footprint, from 1mm sq up to as large as 55mm square. The exterior of the sockets are standard, and the interior interposer, and the pressure plate, and device guides, are modified to accommodate the users particular style of device.

For Any SMT device.
Now available .4mm pitch and up.
DATA SHEETS
Note: Please review the data sheets below. The drawing on the data sheet shows layout of the socket less the interior portion that is modified for your exact device. For your layout, the center datum point is a common dimension for both the IC and socket. Actual drawings with your device are generated for your approval after receipt of order.
