FR-4 is a common material for printed circuit boards (PCBs). A thin layer of copper foil is typically laminated to one or both sides of an FR-4 glass epoxy panel. These are commonly referred to as copper clad laminates. The copper thickness or copper weight can vary and so is specified separately.
[1] [2] They are typically used in printed circuit boards. [3] There are different types of CEMs: CEM-1 is low-cost, flame-retardant, cellulose-paper-based laminate with only one layer of woven glass fabric. [4] CEM-2 has cellulose paper core and woven glass fabric surface. CEM-3 is very similar to the most commonly used PCB material, FR-4. Its ...
This is done through various substrates, both rigid and flexible, most commonly FR4 for rigid, and polyimide for flexible. [1] Silicon and glass are also evaluated as an integration method. [ 6 ] [ 7 ] Interposer stacks are also a widely accepted, cost-effective alternative to 3D ICs .

In March 2020 Rogers filed a complaint against ElastaPro for trade secret violations, claiming that this company had unlawfully obtained Rogers' technical formulations and manufacturing knowhow. [20]
The role of the substrate in power electronics is to provide the interconnections to form an electric circuit (like a printed circuit board), and to cool the components.. Compared to materials and techniques used in lower power microelectronics, these substrates must carry higher currents and provide a higher voltage isolation (up to several thousand vo
The 3 inch upper limit for typical thickness must me a typo, I have never seen a PCB thicker than 0.2 inch. Even those thicknesses are usually pressed from thinner laminates. Copper thicknesses of half ounce is much more common than 2 or 3 ounce, due to multilayer and fine pitch this seems to be the dominant thickness today.
