In semiconductor device final probe operation, either blade or epoxy ring probe cards are used to make electrical connection between the tester instruments and the die. In high pins count and high frequency application, epoxy ring probe card is usu- ally used. Because of the existing problems with the conventional epoxy build block, the Slotted Well Epoxy Build Block is designed to improve probe card quality and reduce production cycle time.
