Product Detail

Multilayer PCBs are built by joining all the number of layers and materials at high temperature and pressure so as to remove any trapped air between the layers. Resin and adhesive material is used to stick the components and different layers together. You can choose from a number of materials such as exotic ceramic, epoxy glass, or Teflon etc. to build your PCB. The different prepreg and core layers are combined and go through the lamination process taking place at high temperature and pressure that helps to melt the layers together. After that the PCB is cooled down to form a hard and solid board.

What is a multi-layer PCB board?

The biggest difference between PCB multilayer boards and single-sided and double-sided boards is the addition of internal power and ground planes. Power and ground nets are primarily routed on the power plane. Each substrate layer on a PCB multilayer board has conductive metal on both sides, and a special adhesive is used to connect the boards together, and there is an insulating material between each board. However, PCB multilayer wiring is mainly based on the top and bottom layers, supplemented by intermediate wiring layers.

Therefore, the design of multi-layer PCB boards is basically the same as that of double-sided boards. The key is how to optimize the routing of the internal electrical layers to make the routing of the circuit board more reasonable. The inevitable product of multifunctional development, large capacity and small volume.

Benefits of Multilayer PCBs (compared to single or double-sided PCBs)

● Higher assembly density 

● Smaller size (considerable savings on space)

● Increased flexibility

● Easier incorporation controlled impedance features.

● EMI shielding through careful placement of power and ground layers.

● Reduces the need for interconnection wiring harnesses (reduces overall weight)
