Protel PCB: Basic Knowledge in Definition, Features, and Advantages

What is a PCB?

A printed circuit board (PCB) is a flat board made of insulating material, such as fiberglass or composite epoxy, with conductive copper tracks printed on its surface. These copper tracks connect various electronic components, such as resistors, capacitors, and integrated circuits (ICs), to create a functional electronic circuit. PCBs are essential in modern electronics, as they provide a compact, reliable, and cost-effective way to assemble and connect electronic components.

Types of PCBs

There are several types of PCBs, each with its specific features and applications:

1. Single-layer PCB: A single-layer PCB has conductive tracks on only one side of the board. These PCBs are the simplest and most cost-effective, making them suitable for basic electronic projects and low-density circuits.

2. Double-layer PCB: A double-layer PCB has conductive tracks on both sides of the board, allowing for more complex circuits and higher component density. The two layers are connected through vias, which are small holes drilled through the board and plated with conductive material.

3. Multi-layer PCB: A multi-layer PCB consists of three or more layers of conductive tracks, separated by insulating layers. These PCBs offer the highest component density and are used in complex electronic devices, such as smartphones, computers, and medical equipment.

4. Flexible PCB: A flexible PCB is made of a thin, flexible insulating material, such as polyimide, with conductive tracks printed on its surface. These PCBs are used in applications that require the circuit board to bend or flex, such as wearable electronics or compact devices.

5. Rigid-Flex PCB: A rigid-flex PCB combines the features of both rigid and flexible PCBs, consisting of rigid sections connected by flexible sections. This type of PCB is used in applications that require both the stability of a rigid board and the flexibility of a flexible board, such as aerospace and military equipment.

What is Protel PCB?

Protel PCB refers to the printed circuit board design software developed by the company Altium, formerly known as Protel. Altium Designer, the current version of the software, is a powerful and comprehensive tool for designing and manufacturing PCBs. It offers a wide range of features and capabilities, making it a popular choice among electronic engineers and PCB designers.

History of Protel PCB

Protel PCB design software has a rich history dating back to the 1980s. The company was founded in 1985 by Nicholas Martin in Tasmania, Australia, under the name Protel Systems Pty Ltd. The first version of the software, Protel PCB, was released in 1991 and quickly gained popularity among electronic engineers and PCB designers.

Over the years, the software has undergone several updates and name changes. In 2001, the company changed its name to Altium Limited, and the software was rebranded as Altium Designer. Since then, Altium has continued to improve and expand the capabilities of its PCB design software, making it one of the most comprehensive and widely used tools in the industry.
