In addition to the above considerations, the thickness of the PCB board also involves some details in the PCB manufacturing process.
1. Selection of PCB materials
Choosing different PCB materials can affect the standard and range of PCB board thickness. For example, the thickness range of PCB boards made of FR-4 material is generally between 0.4mm and 6.0mm.
2. Thickness of Laminate (Multi Layer PCB)
For multi-layer PCBs, the board thickness is generally the sum of the thicknesses of each laminate. For example, for a 4-layer PCB, if the thickness of each laminate is 0.2mm, then the thickness of the entire PCB is 0.8mm.
3. Special needs
In some special application scenarios, very thin or very thick PCB board thickness may be required. For example, some flexible PCBs (FlexPCBs) can have a board thickness of less than 0.1mm, while some high-power electronic devices may require a thicker board thickness to ensure heat dissipation.
