MANUFACTURING METHOD FOR PCB WITH THERMAL CONDUCTOR EMBEDDED THEREIN, AND PCB
A method for manufacturing a PCB with an embedded thermal conductor and a PCB are provided. A sheet of copper-clad ceramic serves as a thermal conductor. A sheet of copper foil having no opening serves as an outer layer of a laminate. A part of the sheet of copper foil covering the thermal conductor is removed after a lamination process, to expose a conductive layer as the outer layer of the thermal conductor. Finally, the outer layer pattern is formed. The sheet of copper foil has no opening before the lamination process, so that the sheet of copper foil has good flatness during the lamination process, thereby avoiding wrinkles. Moreover, the sheet of copper-clad ceramic serves as the thermal conductor, so that a pattern is manufactured on the outer layer of the thermal conductor based on the exposed conductive layer.
Antenna in package structure and manufacturing method therefor
In an antenna in package structure, a plurality of supporting blocks spaced apart from each other are disposed between a first substrate and a second substrate, and an antenna cavity is formed between every two adjacent supporting blocks. Therefore, a height of the supporting block determines a height of the antenna cavity. The supporting blocks spaced apart from each other are located between the first substrate and the second substrate, and at least one of the first substrate or the second substrate adheres to the supporting blocks spaced apart from each other using an adhesive layer.
Method for forming channels in printed circuit boards by stacking slotted layers
A process of fabricating an electromagnetic circuit includes providing three laminate sheets, forming a first feature in a first laminate sheet of the three laminate sheets, and forming a second feature in a second laminate sheet of the three laminate sheets. The second feature is aligned with the first feature when aligning the second laminate sheet with the first laminate sheet. The process further includes stacking the three laminate sheets so that the first laminate sheet is positioned above and aligned with the second laminate sheet and the second laminate sheet is positioned above and aligned with the third laminate sheet. The first feature and the second feature define a contiguous element. The process further includes filling the contiguous element with an electrically conductive material to form an electrically continuous conductor.

Methods may include creating a circuit board by metallizing at least part of a first surface on a first side of a substrate to define at least one metallized area on the first surface, wherein the substrate comprises a ceramic material and includes: the first side, including at least (i) the first surface, and (ii) an elevated surface elevated from the first surface, and a second side opposite the first side; flattening at least partially the elevated surface to a predefined first flatness to create a mounting portion by removing material from the elevated surface; attaching an electronics component to the first surface; and mounting the circuit board on an electronics carrier by adhering at least part of the mounting portion to a mounting surface on the electronics carrier. Flattening at least partially the elevated surface to the predefined first flatness may be carried out by removing the material by areal grinding.

Multilayer resin substrate, and method of manufacturing multilayer resin substrate
A multilayer resin substrate includes resin substrates laminated together, an overlapping portion in which a signal line as a conductor pattern and another conductor pattern overlap each other in a laminating direction of the resin substrates, and a non-overlapping portion in which the signal line and the other conductor pattern do no overlap each other in the laminating direction. A thin portion is provided at a position in the non-overlapping portion near the overlapping portion. The thin portion is a portion of the multilayer resin substrate which has a thickness smaller than the thickness in the overlapping portion in the laminating direction of the resin substrates.
