Common Types of Printed Circuit Boards

Printed circuit boards (PCBs) are the heart of all electronic products, but not all are created equal.  There are many different types of printed circuit boards made from different materials and manufacturing specifications for a broad range of applications.  Since the early 1900’s PCB have evolved considerably and today manufacturers like Advanced Circuits offer a broad range of circuit board fabrication capabilities, laminate materials, and certifications to meet the quality, precision, and performance demands for the latest technology requirements.

Below is a list of the common types of printed circuit boards.  For a complete list of Advanced Circuits’ PCB manufacturing capabilities, click here.

Single Layer PCB

Single layer printed circuit boards are among some of the simplest to design and manufacture.  These boards have a single layer of conductive material (such as copper) on only one side of a non-conductive substrate.

Double Layer PCB

Double layer PCBs have one conductive layer on top of a non-conductive substrate and another conductive layer on the reverse side (top and bottom layers).  The two conductive sides can be connected using plated holes in the substrate that connect to pads on both sides of the circuit board; these are called vias.

Multi-Layer PCB

This term refers to a circuit board that has three or more conductive layers.  The conductive layers are at the top and bottom, as well as at least one conductive layer sandwiched between non-conductive substrate.  Advanced Circuits has the capability to fabricate up to 40 layer boards, but the most commonly used have lower layer counts such as 4, 6, or 8 layer boards.

High Density Interconnect (HDI) PCB

HDI PCBs take advantage of precision based manufacturing technology to pack as much functionality into a small space.  This is done by using many conductive layers, laser drilled microvias, fine lines and tolerances, and advanced laminate materials.  HDI PCBs can accommodate the complex routing of high pin count chips and other high-tech miniaturized components.

High Frequency PCB

The main difference in manufacturing high frequency printed circuit boards pertains to the design itself.  These PCB are designed to facilitate signals over 1 gigahertz.  Depending on the application, high frequency printed circuit boards may require the use of advanced laminate materials and controlled impedance.

Advanced Circuits’ PCB manufacturing capabilities range from the simplest of designs to the most complex builds with rigorous design requirements.  Our capabilities include laser-drilled microvias, cavity boards, heavy copper up to 20 oz., via-in-pad, microwave & RF boards, up to 40 layers and others.  We are your one-stop solution to all of your printed circuit board manufacturing.  For more information about our PCB capabilities and services, contact your Sales Representative or call 1-800-979-4722.
