What Materials Are Used to Make Printed Circuit Boards?

Printed Circuit Boards are also called a PCB.They are inexpensive boards that are used to connect electronic components.

They are often made under high volume production through the electronics industry.Quality control of these boards are maintained through the IPC.

The materials that are used to comprise PCBs are usually made from a copper conduit layer that contains an overlay of laminate. The laminate that covers the board is usually made from an epoxy resin, which is somewhat like a hard plastic. Most of these products are green in color due to the resin that is used to cover the board, which is a green epoxy. However, there are other colors that are available through different types of laminating materials. These materials include cotton paper mixed with epoxy as well as woven glass with epoxy. The standard for creating PCBs, when it comes to materials, is using a thin layer of copper along with a green mask epoxy.

There are a process of electroplating steps that are then used in the board, depending upon how the board is going to be used. These include silk screen printing as well as photo engraving. These processes either etch out the unwanted copper or use a chemical etching process to remove the copper foil.

Some of the printed circuit boards are comprised of several thin boards put together, these are usually known as multi layer boards. Once the PCB is created, the PCBs are mounted with the various components that are needed in order to get them to work properly.

These boards are used in most aspects of the electronics industry and have been around for over 100 years.

Companies that create printed circuit boards can create them specifically for the intention of the customer as well as their needs. Those who have a business in the electronics field can hire a company to create a custom board for their company with the exact specifications that they need to operate their electronic equipment. The printed circuit board will be created from both the conduit and non-conduit materials, provided with the correct electronic components and then tested to make certain that it works properly. It will then be protected in packaging for delivery to the customer.

Businesses can easy find online companies that will be able to provide them with custom printed boards online. As most printed circuit boards are all created from the same type of materials, it often pays to get the boards from an online dealer rather than through a computer or electronics stores.
