Several layers of a substrate board and insulating material isolate the layer in the multi-layer PCBs. These PCBs are available into smaller size that serves the advantages of space and weight. These multi-layer PCBs are going to use in the laptop, smartphone, tablets, GPS trackers, PCs, and more.

Benefits of Multi-Layer PCB:

  • Robustness
  • Flexibility for higher level design
  • Having higher speed of circuit

Rigid PCB:

Rigid PCBs represent to those kinds of printed circuit boards whose are getting to use  base material fabricated from the solid material that are unable to twisted or folded. These PCBs get compose with multiple layers, which enable with copper layer, substrate layer, silk screen layer, and solder mask layer.

They are adhered together being heat and adhesive. But, few circuit board can single side3d, double sided, multi layered or rigid PCBs might be any of them based on the needs. Once designed, they are unable to update or modify. These types of PCBs are going to use in the tablets, mobile phones, X-rays, computer, laptops, GPS tracker, temperature sensors, control tower instrumentation, CAT scans, MRI systems, and so on.

Benefits of Rigid PCB:

  • Less making a noise
  • Capable to absorb vibrations
  • Compact size
  • Cost affordable
  • Easy to make repair and diagnostics
  • Having lightweight

Flex PCB:

Usually, the substrate is getting a flexible board as a flexible plastic. This primary material allows the board to install into forms that inflexible board unable and to turn or shift while using, without most dangerous the circuit on the PCB. Even, this PCB tend to charge more to intend and make as compare to rigid PCBs. Flex PCBs are also present in the market as single-sided, double-sided, and multilayer configurations. Thus, they help to elimination in the complexity of the unit assembly. These PCBs are going to use in the flex solar cell, automotive industries, cellular telephones, organic light emitting diode (OLED) fabrication, LCD fabrication, and more.

Benefits of Flex PCB:

  • Remove the connectors
  • Keep saving space
  • Enhanced repeatability and reliability
  • Offer the uniform electrical characteristic for higher speed circuitry

Rigid-Flex PCB:

Rigid-flex PCB combines technology of rigid and flexible circuit boards. Rigid flex board has a rigid circuit board that connects to a flex circuit board. These types of printed circuit board are able to compound, when design is getting to demand.

Hence, All different kinds of PCBs along with PCB prototyping and manufacturing enable with Sided PCBs, Double Sided PCBs, Multilayer PCBs, Rigid PCBs, Flex PCBs, Rigid-Flex PCBs, and so on. Rigid flex boards can easily design in a compact way, and its lightweight nature that makes them a better solution for the different range of application in the medical, and consumer electronics areas, and aerospace.

Benefits of Rigid-Flex PCB:

  • Enhance resistance
  • Lightweight
  • Eliminate the space requirement via 3D ability
  • 360 degree bendability
  • PCB assembly processes are most simplify

HDI (High Density Interconnect) PCB:

Today, HDI printed circuit boards are going to use in the frequency range of 500MHz – 2GHz. Hence, they can use in many frequency crucial apps such as microwave PCBs, micro strip PCBs, communication systems, and more.

Aluminium Backed PCB:

These types of printed circuit board are getting to use in higher power apps, and aluminium construction assists in the heat dissipation. These PCBs provide the higher degree of rigidity and less level of thermal expansion that makes them ideal for apps getting higher mechanical tolerance. They are going to use in power supplies and LED.

High Frequency PCB:

The major difference for manufacturing higher frequency printed circuit board that consist to design itself. These kinds of PCB are getting to design to facilitate signal over 1 gigahertz. Based on the application, higher frequency printed circuit boards might need apply of enhanced laminate material and controlled impedance.
