What is a Printed Circuit Board?

In electronics, a Printed Circuit Board is a surface constructed by paths or tracks of conductive material on a non-conductive base.

These boards, today, are present in almost all electronic devices. Since its creation in 1936 by Paul Eister, the use of PCBs has been a major breakthrough for electronic devices, as it innovated the connection between elements by eliminating the need for wires.

The simplest printed circuit boards have one or two layers, but there are much more advanced ones that can have up to 28.

To connect each of the elements that make up the board, a series of very thin copper conductive tracks are used to create a conductor rail. The main support of these tracks is a glass fiber reinforced with ceramic materials, resins or other conductive elements.

Printed circuit boards can be made with different substances, but the most commonly used is FR-4, a composition of glass fibers and epoxy resin that has flame retardant capabilities suitable for use in the non-conductive part of printed circuit boards. A copper layer is also added between the FR-4 layers.

At Inelmatic, we design custom PCB's, our in-house electronics department uses the most advanced software to design the PCB with the latest components so that the product fits our customer's needs. We have experience from simple 2 and 4 layer boards upto 12 layers HDI (high density) with impedance control.
