7 Summary

Some very good progress has been made during the past few years in developing fine pitch CSP packages sockets for CSP ball pitch. Sockets are now very common and proposed by most sockets manufacturers with open top or clam shell options.

Texas Instruments Interconnect Business Unit will provide you with a complete range of sockets technology for CSP package. For further information your local TI Field Sales representative can give you up-to-date information or please visit web site http://www.ti.com/snc/products/controls/burnin.htm
