  • Methods and systems for small parts inspection
    Patent number: 6879389
    Abstract: A method of automatically sorting and placing parts for inspection is described which includes orienting the parts within a feeder and delivering the oriented parts from the feeder to an escapement. Once the parts are delivered, they are advanced from the escapement, one at a time, down a ramp, and caught by a resilient material. The parts are then transferred ring from the resilient material to a parts fixture and positioned for inspection in the parts fixture within ±0.001 inch in a vertical direction and within 0.002 inches in x and y directions, x and y defining a horizontal plane.

  • Method of modifying tin to lead ratio in tin-lead bump
    Patent number: 6877653
    Abstract: A method of modifying the tin to lead ratio of a tin-lead bump forms a patterned solder mask over a substrate that comprises a first tin-lead bump formed thereon, the patterned solder mask having an opening that exposes the tin-lead bump. A solder material including tin and lead is filled in the opening of the solder mask over the first tin-lead bump. The solder material has a tin to lead ratio that differs from that of the first tin-lead bump. The solder material is reflowed to fuse with the first tin-lead bump, which forms a second tin-lead bump. The tin to lead ratio of the second tin-lead bump is thereby different from that of the first tin-lead bump.
