Abstract:
The package structure of the PCB comprises a substrate and a frame. The frame is located at the top of the substrate, and the substrate and the frame define a receiving space. The electronic components are mounted on the substrate and distributed in the receiving space. Because of the protection of the frame, the electronic components are effectively protected from the collision of installation in the process or use in the process. The substrate can be a flexible circuit board or a rigid-flex PCB and the electronic components are directly embedded in the substrate. Therefore the thickness of the package structure is reduced.

A 3D circuit module which is highly reliable, easily layered and able to mount electronic components in high density is obtained by providing a support member having a frame in the periphery thereof and a recess; a coating layer for coating the frame and filling in the recess, the coating layer being made of resin material which is adhesive and has a softening temperature lower than the softening temperature of the support member; a wiring pattern formed on the coating layer, the wiring pattern including a first land on the frame, a second land on the recess, and a wiring part for connecting between the first land and the second land; and an electronic component having a projecting electrode formed on a side thereof, the electronic component being bonded to the coating layer and accommodated in the recess, with the projecting electrode connected to the second land.
Abstract:
A solid printed circuit board is manufactured by bonding upper and lower printed circuit boards having different shapes and provided with wirings formed on surfaces thereof. A bonding layer is made of insulating material containing thermosetting resin and inorganic filler dispersed therein, and has a via-conductor made of conductive paste filling a through-hole perforated in a predetermined position of the bonding layer. This circuit board provides a packaging configuration achieving small size and thickness and three-dimensional mounting suitable for semiconductors of high performance and multiple-pin structure.
