20150114572 | DEVICES AND METHODS OF OPERATION FOR SEPARATING SEMICONDUCTOR DIE FROM ADHESIVE TAPE - The embodiments described herein provide an apparatus and method for separating dies from adhesive tape. In general, these techniques use applied vacuum and one or more channels in an extractor base surface to progressively peel adhesive tape away from the die. When the adhesive tape has been peeled away from the entire die the die can be removed and packaged. Such a technique can reduce the strain the die and thus may reduce the probability of cracks occurring in the die, and is thus particularly applicable to removing adhesive tape from relatively thin dies. | 04-30-2015 |

20140093415 | METHOD FOR REPAIRING A COMPONENT FOR USE IN A TURBINE ENGINE - A removed damaged portion of a fully consolidated turbine engine component is replaced with a powder coupon that includes powder particles that are at most partially sintered or are bonded together with a binder. A bonding agent is applied to the component and/or the powder coupon. The powder coupon is then positioned over the component and heat is applied to fully sinter the powder particles, thus causing the powder coupon to shrink onto the component.

Application of such pressure increases the weld zone ductility and reduces likelihood of solidification cracking and strain age cracking, compared to weld zones formed at atmospheric pressure. In some embodiments an isostatic pressure chamber is used to apply isostatic pressure on the weld zone. In other embodiments the welding is performed by laser welding or cladding, TIG welding electron beam welding or autogenous welding. | 07-31-2014 |
