1. A 6-layer PCB, also known as a “multi-layer board,” is typically comprised of three copper-clad laminates.
2. Initially, the metal sheet is cut, and then the inner layers with drilled holes are sequentially sent to the press.
3. After the initial pressing of the 6-layer circuit board, it usually undergoes a second pressing.
4. Subsequently, the board undergoes drilling once more, followed by processes such as copper electroplating for further processing and production.
5. 6-layer printed circuit boards are commonly used in the communications industry.

The 6-layer PCB can accommodate various thickness requirements such as 1.2mm, 1.6mm, 2.0mm, and 3.0mm. Typically, each layer may have different thicknesses, with 1.6mm being the most common for a 6-layer PCB. During the pressing process, the PP and copper foil are subjected to high temperature, causing the resin in the substrate to melt and redistribute. Thus, the press is set to achieve an overall thickness of 1.6mm, with individual layer thicknesses averaged accordingly.
Numerical calculation for a 6-layer board is as follows: Core board = 0.3mm * 2 = 0.6mm, PP = (7628 + 1080) * 4 = 0.96mm, pressed copper foil = 1OZ * 2 = 0.07mm. The theoretical total thickness sums up to 0.6 + 0.96 + 0.07 = 1.63mm.
Additionally, the required thickness can vary based on the PCB’s application:
1. For power boards, thicker copper layers are preferred to ensure operational reliability.
2. For standard precision products, copper foil requirements are generally standard.
Core board = 0.3mm * 2 = 0.6mm, PP = (7628 + 1080) * 4 = 0.96mm, pressed copper foil = 1OZ * 2 = 0.07mm.
