摘要:
An opening is formed in resin 20 by a laser beam so that a via hole is formed. At this time, copper foil 22, the thickness of which is reduced (to 3 μm) by performing etching to lower the thermal conductivity is used as a conformal mask. Therefore, an opening 20a can be formed in the resin 20 if the number of irradiation of pulse-shape laser beam is reduced. Therefore, occurrence of undercut of the resin 20 which forms an interlayer insulating resin layer can be prevented. Thus, the reliability of the connection of the via holes can be improved.

摘要:
A filet F is added to a portion constituting a corner portion C equal to or smaller than 90° in a crossing portion X of wiring patterns 58b, 58c and 58d, and a wiring pattern 58 is formed. Since the filet F is added, the wiring patterns are not made thin and are not disconnected in the crossing portion X. Further, since there is no stress concentrated to the crossing portion X, disconnection is not caused in the wiring patterns and no air bubbles are left between the crossing portion X of the wiring patterns and an interlayer resin insulating layer so that reliability of a printed wiring board is improved.
摘要:
A multi-layer printed wiring board includes a board covered with a conductor layer, an interlayer insulating resin layer, an etched metal film on the interlayer insulating resin layer, and a via hole. The interlayer insulating resin layer has a fibrous substrate. The via hole has an electrolytic plated film and an electrolessly plated film and connects the conductor layer of the board and the etched metal film.
