Posted by Sheraton Veranda on June 20th, 2016

China is a worldwide business hub that most countries are doing business with. An extremely industrialized country, china manufactures all kinds of things. It seems that the country is ahead in every sector, including the electronic industry. One of the electronic products you could get from China is an express pcb. This is a Printed Circuit Board, called a printed wiring board as well. Pcb china companies are numerous and their products are available online.

Incase you think that the only way to have your pcb china delivery is to use the traditional importing methods, you can order them online. There are websites that send your product express as long as you have shared your contact details properly. So shipping will not be a big deal no matter where you live on earth. As you probably know, a pcb begins as a thin, sheet of material without electric work or conductors. It is usually made of fiberglass or the glass fiber epoxy laminate material.

Then, a careful and intelligent electrician makes connections all over the sheet with copper wires and other chemicals. The next step is printing, where a pre-made diagram with connection symbols is attached to the express pcb sheet. This diagram depicts the wiring system that has to be created to connect the components. Now the printing work entails shifting the diagram to the printed wiring board with an acid-proof material. This is because the pcb has to be placed in a lot of acid that is supposed to remove copper from the board.

While it removes copper, the acid will not affect areas that are protected with the acid-proof material. This is why the protected areas on the pcb appears printed. The next work that is done on the board is drilling of holes. Components are mounted to the board via these holes and the sheet itself is to the casing that is meant to safeguard the electronic device being manufactured. Before the process is completed, the board is coated with special coat to keep it free from rust that could arise from traces of copper.

The above process produces a double-sided or a two-layer printed circuit board.  However, pcb China companies are able to come up with any number of layer via the same process.  For instance, an item like a computer has a PCB with up to 12 layers. The minimum you can find has four layers. Since technology has grown a lot, some manufacturers are now skipping the step of drilling holes into the board. Instead, they are soldering components directly to the board to mount them.  By their approach they are finding it easy to attach more components on the surface mount pcb.

Found on nearly all electronic devices on the market, a pcb is such an important item. If you want to learn more about express pcb options from China, just use the internet. You will be able to find different pcb products that might suit your uses right now.   What’s more, you will get them cheaply compared to buying them in your area.
