  • Reusable die carrier for burn-in and burn-in process
    Patent number: 6025732
    Abstract: A reusable carrier 10 for temporarily holding an integrated circuit 12 during burn-in and electrical test includes a base 14 and a lid 16 attached to the base 14 by hinges 18. A flexible substrate 19 is attached to the base 14. Alignment posts 20 have tapered surfaces 22 that engage corners 24 of the integrated circuit 12 to position the integrated circuit 12 precisely on upper surface 26 of the substrate 19. A spring-loaded latch 28 engages projection 30 in aperture 32 of the base 14 to hold the lid 16 closed over the integrated circuit 12. Electrically conductive traces 34 on the surface 26 have contact bumps which engage contact pads on the underside of the integrated circuit 12 to connect the integrated circuit 12 to peripheral contact pads 38 around edges 40 of the substrate 19.
