The present invention refers to a circuit for current and voltage control in a switching power supply controlled on the primary side, comprising a transformer with a primary-sided and a secondary-sided main winding, wherein energy pulses are transmitted from the primary side to the secondary side. Furthermore, a primary-sided switch switches on an off a primary current through the primary-sided main winding. A primary current comparator determines a switch-off time of the switch depending on the primary current. In order to reduce the load dependency of the output voltage, the control variable is variably amplified by a feedback network and additionally the control variable is reduced depending on the output load through a correction network. To reduce noise generated by the energy-rich pulse transmissions at low frequencies and the waviness of the output voltage, the control variable is fed back to the primary current comparator so that the duration during which the primary current flows through the primary-sided main winding is reduced differently. To reduce the susceptance to failure when determining the switch-on time, a comparator voltage depending on the control variable is generated as reference.

The formation of improved reliability conductive traces in touch sensor panels that are less prone to failures due to environmental effects is disclosed. Conductive traces, which can be formed from a stackup of metal layers or a single metal layer, can be protected with an additional photoimageable passivation layer of a material such as an organic polymer. This photoimageable coating can be patterned so that it does not appear in the visible area of the touch sensor panel, with much finer tolerances than conventional passivation layers to help keep product dimensions to a minimum.

A method of forming non-spherically shaped solder interconnects, preferably conical, for attachment of electronic components in an electronic module. Preferably, the solder interconnects of the present invention are cone shaped and comprise of depositing a first solder followed by a second solder having a lower reflow temperature than the first solder. Warm placement of the electronic component at a somewhat elevated temperature than room temperature but less than the solder reflow temperature reduces the force required during placement of a semiconductor chip to a substrate. After warm placement, reflow of the module occurs at the lower reflow temperature of the second solder. The conical shape of the solder interconnects are formed by a heated coining die which may also coin a portion of the interconnects with flat surfaces for stand-offs. The ability of the cone shaped solder interconnects to meet the opposing surface of a chip or substrate at different heights accommodates the camber typically associated with chip and substrate surfaces.

A welded pipe joint having reduced internal stresses comprises a pipe, a socket fitting, and an annular weld. The end surface of the fitting is chamfered in a concave profile, so that the weld profile subtends an angle of from about 100 degrees to about 120 degrees, rather than the customary 90 degrees. The fitting and the pipe are welded together by applying, from outside the pipe, an annulus of added bead metal to the chamfered end surface of the fitting so as to surround the chamfered end surface, and fusing the base metal of the annular wall and pipe. The pipe has no dam or other protuberance to confine the bead of added metal. Prior to welding, the fitting may have an annular lip immediately surrounding the surface of the pipe and may also have a ring spaced from the lip. The ring may be integral with the fitting and spaced from the lip by thin, radially spaced metal bars or may be separate from the fitting.
