New Grypper test sockets handle any BGA devices including large array ASICs and the smallest I/O down to 0.35-mm pitch. The Grypper socket can be designed to any I/O count specific to custom BGA requirements.
The Ironwood Grypper G80 LIF socket, part number GR1005-XXXX, allows the testing of an 896-I/O, 31.0×31.0-pitch BGA package. This design also incorporates built-in alignment corners that simplify the positioning of the small BGA to the socket prior to insertion.
To connect a device, an operator simply inserts the chip into the socket by pressing on top of the device; no lid is required. The unique geometry of the contact grips onto the solder balls of the device. To remove the device a simple extraction tool can be used to pop the device back out of the socket, at which point the socket is ready to receive another device.
This Grypper socket has excellent electrical performance of -1 dB insertion loss to greater than 40.0 GHz. The force required to insert a device is 25 gm/contact. The socket is sold in three configurations; Sockets with a ROHS solder ball (SAC 305) replicates the device. The socket configured with SnPb solder balls allow easy reflow/attachment onto a PCB that already has components mounted. The lower melting temperature of the SnPb solder will not affect any adjacent components that might be close to the target area where the socket is to be placed. The socket can also be purchased with NO solder balls. The no-solder-ball version requires the use of a 0.2-mm-thick stencil for the correct amount of solder paste, allowing any type of solder paste for attachment.
Pricing for the 896 BGA- GR1005-0003 is $1,197.00 at qty 4-10 and the 12 BGA – 109092-0002 is $313.00 which includes the built-in alignment corners. Reduced pricing is available depending on quantity required.
