WINGBACK AND SADDLE TYPE UNITS TEST SOCKET

FOR BURN-IN BOARD

by B. D. Kim BACKGROUND ADVANTAGES OF THE INVENTION

  There are many non-valued added steps in the The newly invented test socket design can be burn-in process of wingback/saddle products. To loaded and unloaded easily by operator and can be reduce these non-value added steps we should auto- automated. Device loading/unloading system into mate the burn-in test process as much as possible. burn-in test board.

PROBLEM DESCRIPTION This will result in productivity increase, quality

The major problem is that the current test socket

improvement and cost saving etc. Figures I and 2

show how to operate the moving contact bar by

using the hinge and spring. The operating theory is that the device can easily be loaded into the socket

while the socket entrance is being widend by push- ing the moving contact bar.

  By excluding the pushing force to moving con- tact bar with loaded device, the connection is made by spring tension and then the test is possible.

is very difficult to insert devices into the burn-in

sockets and many bent leads are created. Of course,

the current test socket is not easily converted to an
automated insertion system.
