Abstract: A printed circuit board includes a group of pads suitable to be soldered to a respective group of solder-balls of a device. Each pad of the group has a crack initiation point on its perimeter at a location where cracks in a solder-ball are anticipated to start after that solder-ball is soldered to that pad. For a pad of that group having a microvia located therein, a center of that microvia is located farther than a center of that pad from its crack initiation point. For a pad of that group having a trace merging along a portion of its perimeter, that portion does not include a vicinity of that crack initiation point.

Abstract: A method of routing or laying out signal traces on printed wire or circuit board in order to improve signal transmission quality. The method includes routing a given signal trace such that it is electrically connected to a rectangular corner of a substantially wider component pin pad and forms an angle of approximately 135 degrees with the proximate sides of the pad, thereby minimizing the impedance discontinuity at the interface or junction of the signal trace and pad and hence minimizing the reflection of the digital signal at the interface or junction.

Abstract: A strengthened semiconductor die substrate and package are disclosed. The substrate may include contact fingers formed with nonlinear edges. Providing a nonlinear contour to the contact finger edges reduces the mechanical stress exerted on the semiconductor die which would otherwise occur with straight edges to the contact fingers. The substrate may additionally or alternatively include plating traces extending at an angle from the contact fingers. Extending at an angle, at least the ends of the plating traces at the edge of the substrate are covered beneath a lid in which the semiconductor package is encased. Thus, when in use with a host device, contact between the ends of the plating traces beneath the lid and contact pins of the host device is avoided.

Abstract: A circuit board has, in a first signal layer, a signal conductor having a relatively small width and a contact pad having a relatively large width. The relatively large width of the contact pad combined with the relatively narrow signal conductor creates an impedance mismatch between the contact pad and the signal conductor. The circuit board has, in a second signal layer, a ground plane separated from the first signal layer by a nonconductive layer. The circuit board defines an opening in the second signal layer underneath the contact pad. The presence of the ground plane underneath the contact pad typically affects the impedance of the contact pad. The opening in the second signal layer removes a portion the ground plane relative to the contact pad and, therefore, reduces the impedance mismatch between the contact pad and the signal conductor. Such reduction in the mismatch of the impedances between the contact pad and the signal conductor minimizes signal reflection of a signal transmitted through the signal conductor and across the contact pad.

Abstract translation: 电路板在第一信号层中具有相对较小宽度的信号导体和具有相对较大宽度的接触垫。 接触焊盘的相对较大的宽度与较窄的信号导体相结合，在接触焊盘和信号导体之间产生阻抗失配。 电路板在第二信号层中具有通过非导电层与第一信号层分离的接地层。 电路板在接触垫下面的第二信号层中限定开口。 接触焊盘下面的接地层的存在通常会影响接触焊盘的阻抗。 第二信号层中的开口相对于接触焊盘去除接地层的一部分，因此减小了接触焊盘和信号导体之间的阻抗失配。 接触焊盘和信号导体之间的阻抗失配的这种减少使通过信号导体传输的信号和接触焊盘的信号反射最小化。

Abstract: An injection-molded part (1) includes elevations (2) and/or depressions (12) arranged between integrated printed conductors (4). If the elevations (2) or depressions (12) are uncoated and thus electrically insulating, they increase the effective voltage clearances between the printed conductors (4) and the components (3) arranged next to the printed conductors (4). The geometric distances can then be reduced. Alternatively, by electroconductively coating the elevations (2), electric and magnetic shielding is achieved in a simple manner. A cover (6) is provided as a top of a box which uses elevations (2) as side walls. A tapering portion (5) connects coatings (7,7') of the cover (6) and elevations (2) via a printed conductor (8) running diagonally across the tapering portion (5).
