Abstract
A sheet for manufacturing a component carrier includes a first structure having first filler particles in a resin matrix, and a second structure stacked with the first structure and having second filler particles in a resin matrix, wherein a hollow volume in a respective one of the second filler particles is larger than in a respective one of the first filler particles.
Claims20
A sheet for manufacturing a component carrier, the sheet comprising:
- a first structure comprising first filler particles in a resin matrix;
- and
- a second structure stacked with the first structure and comprising second filler particles in a resin matrix;
- wherein a hollow volume in a respective one of the second filler particles is larger than in a respective one of the first filler particles.
1 more element
A component carrier, comprising:
- a stack comprising at least one electrically conductive layer structure and at least one electrically insulating layer structure;
- wherein the at least one electrically insulating layer structure comprises hollow filler particles having a larger hollow volume next to the at least one electrically conductive layer structure than in a surface region of the stack.
A manufacturing method, comprising:
- forming a first structure with first filler particles in a resin matrix;
- forming a second structure with second filler particles in a resin matrix;
- stacking the first structure with the second structure to thereby form a sheet;
- and
- configuring the first filler particles and the second filler particles so that a hollow volume in a respective one of the second filler particles is larger than in a respective one of the first filler particles.
