Abstract:
A solder joint between a capacitive element and a ferrule of a filtered feedthrough assembly for an implantable medical device is formed from a solder pre-form mounted on a portion of an external surface of the capacitive element, which portion of the external surface may be overlaid with a layer including a noble metal. Another solder joint may be formed between the capacitive member and each feedthrough pin; and, for an assembly including a plurality of feedthrough pins, each of the other solder joints may be formed from a solder pre-form mounted onto the external surface of the capacitive element by inserting each pin through a corresponding ring of a plurality of rings connected together to form the solder pre-form.
Abstract:
Recently, there is a tendency to increase semiconductor device power. A material used for a heat sink substrate for semiconductor apparatus should have a small thermal expansion coefficient and a high thermal conductivity. A cladding material comprises a first material layer (10) and a second material layer (16), which are alternately stacked. The second material has a smaller thermal expansion coefficient than that of the first material and a lower thermal conductivity than that of the first material. At least five layers consisting of the first material layers and the second material layers are stacked.
Abstract:
In a case of stopping a motor (3) when welding is completed, the motor can be stopped, not depending on the length of a control line, by arranging a first motor stopping means (5a) or a second motor stopping means (5b) in a supplying means (2).
Abstract:
There is provided a bonding material and a bonding method which enable lead-free bonding that can replace high-temperature soldering. The bonding material of the present invention comprises a dispersion in an organic solvent of composite metallic nano-particles having such a structure that a metal core of a metal particle having an average particle diameter of not more than 100 nm. The bonding material can be advantageously used in a stepwise bonding process containing at least two bonding steps.
Abstract:
A laser beam is irradiated on a workpiece (W) to transform a portion of the inside of the workpiece, the portion being at a focal point of the laser beam, thus putting a dot in each predetermined area. A laser marking device has acquiring means (10, 20), coordinate setting means (30), and laser marking means (40). The acquiring means (10, 20) acquire, as information on a dot, at least two-dimensional position information of an exposed section of a workpiece (W) and density information of the dot. The coordinate setting means (30) calculates, for each dot according to the density information, dot depth information showing the distance from the surface of the workpiece (W) to the dot in the thickness direction of the workpiece (W), and the coordinate setting means (30) sets three-dimensional coordinates for each dot based on positions specified by the dot depth information and the two-dimensional position information. The laser marking means (40) performs marking with the three-dimensional coordinates as a laser beam focal point.
Abstract:
The invention relates to a method for producing an electrical connection between a first contact surface and a second contact surface, whereby a contact wire is arranged between the contact surfaces using a wire bonding device by contacting the contact wire to the first contact surface and then guiding it towards the second contact surface to contact the latter and subsequently separating it using the wire bonding device. According to the invention, after the contact wire (20) has been separated from the second contact surface (14) using the wire bonding device (28), the contact point (24) is fitted with an additional contact protection element (34') using the contact wire (20).
Abstract:
Die vorliegende Erfindung bezieht sich auf eine Anordnung (1) zur elektrischen Verbindung eines ersten Bauteils (3) einer Fahrzeugkarosserie aus einem ersten elektrisch leitenden Werkstoff und eines zweiten Bauteils (4) der Fahrzeugkarosserie aus einem zweiten, sich von dem ersten Werkstoff unterscheidenden elektrisch leitenden Werkstoff mit einem Verbindungselement (2), welches einen ersten Verbindungsabschnitt (17) aus dem ersten Werkstoff und einen zweiten Verbindungsabschnitt (18) aus dem zweiten Werkstoff aufweist, und welches derart verformbar ausgebildet ist, dass der erste Verbindungsabschnitt (17) für eine feste Anbindung an dem ersten Bauteil (3) mit demselben und der zweite Verbindungsabschnitt (18) für eine feste Anbindung an dem zweiten Bauteil (4) mit demselben in Anlage bringbar ist.
Abstract:
The invention relates to a first component which comprises a weld projection (8), especially for laser welding, having an indent (10) that is disposed in a first component (4) and that can be welded together with at least one second component (6). The invention is characterized in that the weld projection (8) has a projection (14) and can be brought into contact with the second component (6) via said projection. The invention also relates to a shielding housing (1) comprising such a weld projection (8) for a lamp base.
