Abstract: A sintering press for sintering electronic components on a substrate is provided. The sintering press includes a pressing unit having a plurality of controllable presser rods to apply sintering pressure to the electronic components to be sintered, reaction elements forming a support plane for a respective substrate, an element plate slidably supporting the reaction elements, and a heating circuit with heating elements embedded in a heating body placed around the element plate to bring the element plate to a sintering temperature. A heat diffusion plate is placed in contact with the heating body and extends onto the element plate between the reaction elements, the diffusion plate being made of a material having a higher thermal conductivity than the element plate.

Abstract: A sintering press to sinter electronic components on a substrate comprises a pressing unit comprising a multi-rod cylinder having a front head and a rear head which jointly delimit a compression chamber. In the front head, presser rods parallel and independent of each other are slidingly supported. Each presser rod is coaxial and barycentric to a respective electronic component to be sintered and has a thrust section proportional to the force to be applied to the respective electronic component. In the compression chamber a sealing membrane extends, which is deformed so as to abut against the presser rods for transferring the sintering pressure on each presser rod.

Abstract: A sintering press for sintering electronic components on a substrate includes at least one reaction element extending along an element axis parallel to a pressing axis of the sintering press between a first element end and a second element end, the first element end forming a support plane for a respective substrate, at least one load cell operatively connected to the second element end, and an element plate slidably supporting the at least one reaction element and equipped with a heating circuit. The reaction element has a heating portion passing through the element plate and transmitting by conduction heat of the element plate to the substrate. The reaction element has a cooling portion ending with the second element end and shaped to dissipate the heat transmitted from the element plate to the heating portion.

Abstract: A pressing group for a sintering press to carry out sintering of electronic components on a substrate has a multi-stem cylinder having a front head and a rear head together delimiting a compression chamber. In the front head pressing stems are slidingly supported, parallel and independent from each other, the rear ends of the pressing stems protruding into the compression chamber. In the compression chamber, an actuating flat gasket extends over the rear ends of the pressing stems. The actuating flat gasket is fixed to the front head by an anchoring frame engaging a peripheral portion of the actuating flat gasket, the anchoring frame being completely housed in the compression chamber so that the pressurized fluid also acts on the anchoring frame.

Abstract: A piston for a die-casting machine, in particular with a cold chamber, comprises a stem which extends from a proximal end to a distal end along a piston axis and a piston head which extends from the distal end of the stem and which has a side wall with at least one sealing area suitable to form a seal on the wall of said container of the press. A lubrication circuit suitable for favoring the sliding of the piston comprises first lubrication ducts made in the stem and ending at the distal end of said stem, and second ducts made in the piston head, fluidically communicating with said first ducts and coming out in the lateral wall at least in correspondence with said sealed area.
