Every Electronic PCB Manufacturing Company that excels in the business usually starts by selecting the appropriate materials for a specific project. The objective is to always use the right raw materials for making the boards. At the same time, the company aims to meet the requirements associated with electricity and temperature.
Copper foil
So, what are the constituent materials of a printed circuit board? The first one worth mentioning is the copper foil. It’s present on the outermost layers and works as the conductor of electric signals and currents. It facilitates the flow of these two things between the components. Manufacturers produce copper traces on a PCB by etching the foil.
Prepreg
The prepreg is a form of reinforcement sheet on the RF Circuit made of woven glass combined with a resin. It’s a B-stage material that the manufacturers use before it cures fully. The tackiness of the material allows the bonding of the foils and laminates. The fabricators of prepreg add multiple epoxy combinations and glass weaves.
Copper clad laminates
The manufacturers of PCBs produce cores that constitute prepreg laminated and cured with copper foils on both sides. Manufacturers provide a massive variety of cores with varying thicknesses, epoxy properties, and glass weave types. The designers define the need for combinations suited perfectly for their exclusive applications.
