摘要:
A printed circuit board (PCB) is disclosed. The PCB (200) includes a substrate (202) have a top surface (202a) and a bottom surface (202b). A first conductive layer (203) is disposed on the top surface of the substrate. The first conductive layer comprises a first signal net (203a) and a second signal net (203b). An outermost insulating layer (204) is disposed on the top surface of the substrate to cover the substrate and the first conductive layer. The outmost insulating layer comprises an opening (209) to expose a portion of the second signal net. And, a second conductive layer (207) is disposed on the outermost insulating layer and substantially covering at least a portion of the first signal net. The second conductive layer is filled into the opening to electrically connect to the second signal net which is able to provide one of a ground potential and a power potential. The thickness of outermost insulating layer (204) is less than 1 mm.

An electronic component housing package and the like capable of reducing time of infrared heating operation are provided. An electronic component housing package (10) includes an insulating substrate (1) including a plurality of insulating layers (11) stacked on top of each other, an upper surface of the insulating substrate (1) being provided with an electronic component (4) mounting section. The plurality of insulating layers (11) each containing a first metal oxide as a major constituent. The insulating substrate further includes a first metal layer (2) in frame-like form disposed on an upper surface of an uppermost one (11) of the plurality of insulating layers (11). The first metal layer (2) contains a second metal oxide which is higher in infrared absorptivity than the first metal oxide.

Multichannel RF Feedthroughs. In some examples, a multichannel RF feedthrough includes an internal portion and an external portion. The internal portion includes a top surface on which first and second sets of traces are formed. Each set of traces is configured as an electrical communication channel to carry electrical data signals. The external portion includes a bottom surface on which the first set of traces is formed and a top surface on which the second set of traces is formed. A set of vias connects the first set of traces between the top surface of the internal portion and the bottom surface of the external portion.

A semiconductor device is a resin package structure including a semiconductor element T1 molded with a first resin 6. The first resin 6 contains a filler 7 including an electrical insulating capsule enclosed with a phase-change-material that absorbs ambient heat and phase-changes so as to increase a dielectric-strength. The effect of the filler 7 achieves a structure with satisfactory heat dissipation and a high withstand voltage.

The disclosure discloses a wireless terminal with a reduced Specific Absorption Rate (SAR) peak. The wireless terminal comprises a Printed Circuit Board (PCB), wherein a fractal gap is formed at an edge of a metal ground on the PCB to disturb distribution of induced current at the edge of the metal ground. The disclosure also discloses a method for reducing an SAR peak. On the premise of the non-influence on the communication quality of the wireless terminal, the SAR and the production cost can be reduced and the structure space of wireless terminal can be saved by using the wireless terminal and the method.
