STATEMENT OF PROBLEM: SOLUTION TO PROBLEM:

  Numerous Power life test trays were manufac- Surface mount socket adapter. Manufacture a cir- tured using a standard TO-220 sockets for insertion cuit board with snap out case outlines adapters of mount devices. The increased emphasis on Surface TO-220 and TO-247 type packages. Each snap out Mount Power Products devices dictate that the vari- will have standard semiconductor pad sizes with pin ous SMD be soldered to PC. Boards prior to life interconnects for both sense and power. The circuit test, electrical characterization, or high/low temper- board can then have individual devices mounted by ature electrical measurements. Replacing existing life standard pick and place soldering methodology in test trays is both expensive and a long lead time strip form. The individual socket adapter with the item. Mounting units on multiple circuit boards cre- test units soldered in place can then be scrapped ates problems in board rework when analysis is out of the PC. board and inserted in the already required. existing life test sockets as shown in the picture below

These "Snap Out Adapters" are now available and in use by Motorola Power Products Division, Phoe- nix. Arizona.
