Flex & Rigid-Flex PCBs.. 1-5 Day Quick Turn


Superior & Trusted Flexible, Rigid-Flex & Rigid PCBs for Over 25 years

Multi Layers PCBs

Multi-layer PCBs are printed circuit boards, which comprise of more than two copper layers like 4L, 6L, 8L, etc. The multilayer PCBs are compact sized, and offer benefits of weight and space. Due to these benefits, the multilayer core PCBs are used in various aerospace, as well as mission-critical military applications. Rigiflex provides consistent quality multilayer, impedance controlled, and HDI PCBs in various specifications. We provide these circuit boards at fastest turnaround times, and assured low prices than others.

Advantages of Multilayer PCBs

The multilayer PCBs provide several advantages over single layer PCBs, which makes them popular across various industries. Few of the advantages are as follows:

  • High Assembly Density: Multilayer PCBs have high assembly density than single layer PCBs, which help us build compact PCB packages. These circuit boards reduce the need for interconnection wiring harnesses.
  • High Flexibility: These PCBs feature two or more layers, which are stacked together with a mutual connection between them. There are three conductive layers in any single multilayer PCB – with two layers on the outer side, and one layer in the board. This construction allows high flexibility. Also, this construction allows easier impedance control.
  • Low EMI Shielding: The EMI shielding in these circuits are lowered through the careful organization of ground, as well as power layers.

Applications of Multilayer PCBs

The following are a few applications that use multilayer PCBs:

  • File Servers
  • Weather Analysis Equipment
  • Atomic Accelerators
  • Space Probe Equipment
  • Nuclear Detection Systems
  • Heart Monitors
  • Fiber Optic Receptors
  • Satellite Systems
  • Signal Transmission Systems
  • Satellite Systems
