Chipscale
Package (CSP) Series
 |
Open
top, zero insertion force suitable for automated
load/un–load
|
|
|
Reliable
pinching action contact minimizes solder ball damage
|
|
|
Small
socket outline to maximize burn–in board density and
process through–put
|
|
|
Low
actuation force
|
|
|
Changeable adapter stage to allow a variety of
package sizes
|
The CSP
employs a "pinch" or dual–beam style contact that
interfaces the sides of each solder ball at multiple
points. Excessive disruption of the package solder
ball geometry, on the bottom surface, can lead to
assembly and reliability problems farther down the
line. By interfacing the non critical sides of each
solder ball and incorporating a superior contact
design, the socket ensures electrical continuity,
minimizes ball deformation, and eliminates potential
manufacturing and reliability problems in the end
package.
Since TI's burn–in test is cost–effective and
available in high volume, manufacturers no longer
have to rely on random testing to ensure quality.
Design Features
|
|
|
Open top
auto–load cover actuated socket
|
|
|
Mechanical contacts touch each solder ball
individually and independently
|
|
|
Contact
protrusions pierce oxide on solder ball and give
reliable contact
|
|
|
Contacts
touch the upper side of the solder balls to minimize
ball damage
|
|
|
Once the
IC package is properly seated in the socket, latches
clamp the IC package in position to prevent movement
caused by vibration
