Abstract: Methods and apparatus are provided for designing and laying out multi-layer circuit substrates, such as multi-layer PCBs. Dynamic vias are provided on intermediate PCB layers. Each dynamic via has features that adjust based on the trace layout of the corresponding intermediate layer. In particular, each dynamic via has a second radius R2 if the via is not connected to any trace on the corresponding intermediate layer. If a trace is connected to a dynamic via, the via radius changes from the second radius R2 to a first radius R1, where R1 is greater than R2.

Abstract: A process for laser forming a blind via in at least one layer of a circuit substrate having a plurality of capture pads of varying geometry can include, for at least one blind via to be formed in at least one layer of a circuit substrate, evaluating a capture pad geometry value (such as area and/or volume) within a predetermined distance from a drilling location with respect to a blind via geometry value (such as area and/or volume) to be formed at the drilling location. The process can include setting at least one laser operating parameter based on the evaluation in order to obtain a desired capture pad appearance after blind via formation. The process can include imaging a capture pad area defined as an area within a predetermined distance from a blind via drilling location in at least one layer of a circuit substrate, quantifying at least one appearance value for the imaged capture pad area, and determining an acceptability of the imaged capture pad areas based on the quantified appearance value.

Abstract: A semiconductor device 100 has such a structure that a semiconductor chip 110 is flip-chip mounted on a wiring board 120. The wiring board 120 has a multilayer structure in which a plurality of wiring layers and a plurality of insulating layers are arranged, and a first electrode pad 130 is formed on a chip mounting side. A taper surface 132 of the first electrode pad 130 has a gradient in an orientation reduced in an upward direction toward a solder connecting side or a chip mounting side. Therefore, a holding force for a force applied to the solder connecting side or the chip mounting side is increased, and furthermore, the taper surface 132 adheres to a tapered internal wall of an insulating layer of a first layer so that a bonding strength to the insulating layer is increased.

Abstract: Method and apparatus are disclosed for flow control over Point-to-Point Protocol (PPP) data links. A method of negotiating such flow control between two PPP peers is disclosed, along with methods for operating flow control across a PPP link. In one embodiment, flow control frames carry an IEEE802.3x MAC control frame payload—the PPP implementation repackages such frames as MAC control frames and passes them to a MAC, which performs flow control. In another embodiment, flow control frames allow flow control commands to be applied differently to different service classes such that PPP flow can be controlled on a per-class basis.
