摘要:
In some examples, a fluidic conductive trace based radio-frequency identification device may include a flexible substrate layer including a channel, and a trace formed of a conductive fluid that is disposed substantially within the channel. The fluidic conductive trace based radio-frequency identification device may further include a sealing layer disposed on the flexible substrate layer and the trace to seal the conductive fluid in a liquid state within the channel.

摘要:
Disclosed are a printed circuit board and a method of manufacturing the same. The printed circuit board includes a core insulating layer including an isotropic resin, a first circuit pattern filled in a circuit pattern groove at an upper portion or a lower portion of the core insulating layer, a first insulating layer provided in a top surface thereof with a circuit pattern groove and covering the first circuit pattern, and a second circuit pattern to fill the circuit pattern groove of the first insulating layer. A material, such as polyimide, having an isotropic structure is employed for the core insulating layer, thereby preventing the substrate from being bent without glass fiber. Since the glass fiber is not included, the buried pattern is formed at the upper portion or the lower portion of the core insulating layer, so that the thin substrate is fabricated.

Provided is a printed circuit board, including: a core substrate including an internal circuit pattern on an upper surface or a lower surface; electronic devices which are formed to pass through the core substrate; an external insulating layer which covers the internal circuit pattern and the electronic devices; and an external circuit pattern which is formed on an upper surface of the external insulating layer, wherein a lower surface of the electronic devices protrudes from the lower surface of the core substrate to a lower part. Accordingly, in the embedded printed circuit board in which the electronic devices are embedded, when the electronic devices are mounted, because the insulating layer is formed regardless of a thickness of the electronic devices, the printed circuit board having a desired thickness regardless of the thickness of the electronic devices can be formed.

The invention relates to a carrier (1) for electrically connecting a plurality of contacts of at least one chip (70-1) applied to the carrier (1) of a plurality of chips (7, 70) to each other, comprising holes (2) closed on one side by metal contacts (5) and/or metal contacts of chips, so that blind holes open toward the top side of the carrier are produced. The carrier (1) is immersed in a fluid bath having electrically conductive solder or metal under vacuum. In the immersed state, the environment of the carrier (1) is placed under negative pressure so that the holes (2) of the carrier (1) including the lower surface of the carrier are completely filled with metal conductive material after cooling and solidification of the solder (10), whereby the complete wiring of the carrier (1) is completed by the solder (10).
摘要:
The embodiment relates to a printed circuit board. The printed circuit board includes an insulating substrate having a plurality of circuit pattern grooves, a conductive absorption layer including conductive particles absorbed into inner walls of the circuit pattern grooves and circuit patterns formed on the conductive absorption layer such that the circuit pattern grooves are filled with the circuit patterns. Since the electroplating process is selectively performed with respect to inner portions of the pattern grooves by using the conductive absorption layer as a seed layer, the plating layer is not formed on the insulating layer except for the pattern grooves, so that the etching process for the electroplating layer is not necessary and the patterns are stably formed.
