Multi-layer PCBs

Multilayer PCB Manufacture

Multi-layer PCBs further increase the complexity and density of PCB designs by adding additional layers beyond the top and bottom layers seen in a double-sided configuration. They can be regarded as expansion of double-layer PCBs. With the availability of over thirty layers in multilayer PCBs configurations, The designers of MOKO to produce very dense and highly complex designs. Quite often the extra layers in these designs are used as power planes, which supply the circuit with power also reduce the electromagnetic interference levels emitted by MOKO’s designs. Lower EMI levels are achieved by placing signal levels in between power planes. It’s also of note that increasing the number of power planes in a PCB design with increase the level of thermal dissipation a PCB can provide, which is important in high power designs. Similar to double-layer PCBs, components on multi-layer PCBs are interconnected with each other through holes or vias as well.

Advantages of multi-layer PCBs include:

  • Capable of implementing multiple functions;
  • Reduction of board size and weight;
  • Higher level of density and flexibility;
  • Better at dealing with interference.

Manufacturing multilayer circuit boards is a straightforward process but does require a high level of attention to detail. Care must be taken to ensure all layers are correctly registered to the required drilled holes despite the deformation stresses produced by the heat and pressure. The buildup requires the operator ensures correct materials are chosen, the build sequence is followed and the orientation of each sheet is correct. At MOKO, we have the capacity to manufacture and design up to 18 layers’ PCB.

MOKO’S software features have helped customers get consistently PCBs as they want and you can expect even better results of your multilayer PCB production.
