Here, we are going to know why we design a Multi Layer PCB or why Multi Layer PCB design is required?
Here are some of the points (reasons) based on we can understand why it is required to have a multi player PCB design?
- If weight and volume savings in interconnections are the overriding considerations
- When the complexity of interconnection in sub-systems requires complicated and expensive wiring or harnessing
- If frequency requirements call for careful control and uniformity of conductor wave impedance with minimum distortions and signal propagation, and where the uniformity of these characteristics from board-to-board is important.
- When coupling or shielding of a large number of connections is necessary with multi-layer, all interconnections can be placed on internal layers, and a heat sink of thick solid copper should be placed on the outer surfaces.
