Multi Layer PCB

Multilayer PCB is made up of more than two layers using conductive copper foils and prepreg material, pressed and bonded together. Multilayer is most complex printed circuit board by design and by manufacturing. Nowadays, up to 40 layers of multilayer PCB is possible to manufacture using advanced machinery. CircuitWala has capabilities to make multilayer PCB up to 6 layers.

Multilayer PCBs are complex to manufacturer but high speed by functionally. Multilayer PCB are mainly used professional electronic equipment like computer, mobile, medical devices, aerospace and defense application devices.

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

  • Higher Assemblage Density
  • Reduced Size (considerable savings on space)
  • Enhanced Flexibility
  • Easier Incorporation Controlled Impedance Features
  • EMI Protecting through Careful Placement of Power and Ground Layers
  • Reduced need for Interconnection (Wiring Joints reducing the overall weight)
