Multilayer PCBs

Multilayer PCBs


A multilayer PCB is made of minimum three copper foil layers and has umpteen applications across industries. Multilayered PCBs are smaller and lightweight than single- and double-sided ones. They are available in rigid, as well as flex types. The number of layers you require in your multilayer PCB depends upon the application area. As a leading multilayer PCB manufacturer, Sierra Assembly offers numerous variants of multilayer PCBs across sectors.

Construction of Multilayer PCBs

As one of the leading multilayer PCB manufacturer, Sierra has adopted the best manufacturing practices and most of our multilayer PCBs have four to twelve layers, normally in even numbers, depending upon the application. As mentioned before, these layers are of conductive copper and appear to be double sided. They are laminated with a heat protection material layer that insulates them. These layers are positioned on the outer surface to enable connection with the concerned device. The electrical connections are done through holes and blinds. The best part about this variant of PCBs is that it is designed to work as a single cohesive unit and hence require only a single connection point in the product into which it is fitted.

Benefits of Multilayer PCBs

The most obvious advantage of multilayer PCBs is that they are compact sized and lightweight. When compared with single sided PCBs and otherwise, multilayer PCBs have many benefits. Here are a few of the other advantages:
  • When compared to single-sided PCBs, multilayer PCBs have a much more advanced design functionality and features such as greater EMI shielding and controlled impedance features.
  • The design of these PCBs and their layer helps eliminate the old PCB issues such as noise, crosstalk, and stray capacitance.
  • These are extremely durable, as well as flexible enough to withstand all the heat and pressure that binds the layers.
  • Their single connection point ability is beneficial when designing final electronic product.
  • They have a high assembly density that helps improve their capacity and the overall functionality.

Applications of Multilayer PCBs

Multilayer PCBs have several application areas ranging from computers, medical equipment, and wearable devices to satellite systems, signal transmission, nuclear detection systems, and many more. They have a large application in these industries:
  • Defense
  • Aerospace
  • Electronics and Telecommunication
  • Satellite
  • LED & Electrical
  • Wireless
  • Manufacturing
