Copper printed circuit boards have been around for some time. They are being used more all over the world. The main purpose of this board is to transfer current and signals in a safe manner. This board is also known as CTS or ribbon technology. The other main technology is using plastics as the insulator, but it does not compare at all with the performance offered by copper printed circuit boards.

When designing copper printed circuit boards the first parameter that needs to be considered is the thickness. The thickness of this board must be lower than 4 milimeters otherwise the thermal expansion resistance becomes an issue. The other general parameters to consider before and during the fabrication of any such board, but mainly focuses on boards containing copper traces with a thickness of 3 milimeters.

The other key parameter to consider is the mechanical strength of the board. This is measured in terms of its R-value. The higher the R-value, the higher the thermal conductivity of the board and the less conductive it becomes. So, the higher the R-value, the better conductor it is and the less the electrical resistance. Another important parameter to consider is the thermal expansion resistance and this is measured in inverse degrees. The higher the rating of the thermal expansion resistance, the thicker the board becomes which means it is more rigid.

When designing copper-based PCBs the top most parameter is the thermal resistance. It is achieved through anisotonic shaping of the boards with the help of special tools. After the shaping, the PC board is then placed in an oven. This heat treatment activates the formation of dipoles which have the ability to conduct and store electricity. Due to this property, the thickness of the board increases and the overall weight goes down as it is able to absorb electricity.

Another important parameter to consider is the mechanical rigidity of the board. PC materials are generally manufactured from polyester and dipole material. These materials are generally very rigid and do not change too much when exposed to different environmental conditions. The most important aspect about copper traces is that they are incorporated into the polymer material and are thus incorporated with the copper traces.

Finally, the surface tension of the material plays a vital role in determining the weight of the job. The copper traces are held tightly in the pcb due to the heat and pressure applied to them during the manufacturing process. So, they form the thin layer on the top most part of the PCB.
