Abstract: A lead frame for an integrated electronic device includes a die pad made of a first metallic material. A top coating layer formed by a second metallic material is arranged on a top surface of the die pad. The second metallic material has an oxidation rate lower than the first metallic material. The top coating layer leaves exposed a number of corner portions of the top surface of the die pad. A subsequent heating operation, for example occurring in connection with wirebonding, causes an oxidized layer to form on the corner portions of the top surface of the die pad at a position in contact with the top coating layer.

Abstract: The invention relates to a polymer film obtainable from the crosslinking reaction between pectin and carboxymethylcellulose in the presence of an organic calcium salt and a plasticiser. The film can comprise zeolite, loaded or not loaded with silver ions. The organic calcium salt is selected from: calcium propionate, calcium acetate, calcium lactate, calcium sorbate, calcium glutamate, calcium oleate, calcium palmitate, calcium laurate, calcium stearate and calcium myristate. The plasticising agent is a saturated or unsaturated fatty acid selected from: oleic acid and palmitic, stearic, lauric, myristic, myristoleic, palmitoleic and linoleic acid; polyethylene glycol; glycerol; glycerol derivatives; and citric acid salts, preferably sodium citrate. The polymer film can be laminated to at least one film/layer of plastic material, possibly biodegradable, or to a layer of paper and used for packaging foods, in particular baked products, with the aim of preserving them and extending their shelf life.

Abstract: Sheet placing apparatus, configured to lay a protective cover sheet over a palletized load, includes movement means that support and/or move the palletized load, a picking up and positioning device for the cover sheet and a feeding device having a reel assembly configured to rotatably support a reel of film from which a plurality of the sheets can be obtained, by unwinding and cutting the film of the reel. The reel assembly is configured to be positioned in an operating position below the palletized load along the advancement line of the palletized load by making available an edge of the film which comes out of the movement means to be grasped by the picking and positioning device which lifts the film from below to the top of the palletized load.
